1.0 EXECUTIVE SUMMARY The Central Valley Regional Water Quality Control Board’s (Central Valley Water Board) San Joaquin River Surface Water Ambient Monitoring Program (SWAMP) was implemented in October 2000 as part of the statewide effort to assess and monitor California’s surface water quality. The San Joaquin River (SJR) Basin covers 17,720 square miles (CVRWQCB, 1998) with fresh water flows originating from the Sierra Nevada along the east side and ephemeral streams providing seasonal flows along the west side and within the foothill regions. The hydrology of the basin has been highly modified and regulated since the advent of the Central Valley Project in the late 1940’s, and the valley floor is dominated by irrigated agriculture (approximately 2.0 million acres (DWR, 2001)). The SWAMP within the SJR Basin was designed with a 3-tiered monitoring framework: 1) long-term monitoring in the main stem of the river; 2) long-term monitoring in selected tributaries draining major sub-basins; and 3) more intensive monitoring on a 5-year rotation within the sub-basins themselves. This report focuses on the results for the first two tiers of the SWAMP effort, the main stem of the San Joaquin River and the major inflows from sub-watersheds, between October 2000 and September 2005. Results for the third tier, the Intensive Basin Monitoring Program (IBP), can be found on the fol-lowing website:

http://www.waterboards.ca.gov/centralvalley/water_issues/water_quality_studies/surface_water_ambient_monitoring/sjr_swamp.shtml The final sampling design for the first two tiers included eight SJR main stem sites and 30 drainage ba-sin sites, which were sampled monthly or weekly depending on the site, with a total of 39 separate con-stituents sampled over the course of the sampling period. At a minimum, each site was analyzed for standard field measurements (specific conductance, pH, temperature, turbidity, and dissolved oxygen) as well as total coliform and E. coli. Monthly photo documentation was taken at each site. Sampling expanded to include total organic carbon, total suspended sediments, trace elements (arsenic, copper, chromium, lead, nickel, zinc, and mercury), biochemical oxygen demand, mineral data (chloride, sul-fate, calcium, magnesium, total dissolved solids, carbonate, bicarbonate, total alkalinity and sodium) and water column toxicity when additional funding was available. The purpose of this report is to summarize the data gathered over the five year sampling period and attempt to address the SJR SWAMP’s main questions within the SJR valley, which include evaluating spatial and temporal trends and providing a preliminary assessment of potential beneficial use con-cerns. Constituents monitored displayed distinct spatial and temporal trends within the SJR watershed and some areas were identified for further review of potential impacts to beneficial uses. Spatial Trend Findings: Within the river, the majority of constituents, i.e. specific conductance, TSS, turbidity, and most miner-als and metals demonstrated increasing concentrations from Sack Dam (essentially the headwaters of the lower SJR) to Hills Ferry (a main stem site just upstream of the first freshwater flow from the Sierra Nevada). Many of the increases corresponded with inflows from the Grassland sub-basin. A pattern of decreasing concentrations from Hills Ferry to Vernalis (the boundary of the Sacramento-San Joaquin Delta) corresponded to dilution from the high volume fresh water flows from the east-side rivers that drain the Sierras. Most constituent concentrations decreased to roughly the same concentrations at Sack Dam after the 110-mile journey to Vernalis.

Comparing tributary sub-basin inflows, those from the western side of the SJR Basin had higher con-centrations of most constituents than those on the eastern side. The distribution may in part be due to minimal natural run off from the Coastal Range and replacement supply water from the Delta along the west side and more continuous fresh water flows and captured snowmelt as supply water for the east side. Temporal Trend Findings: Strong seasonal trends were found for temperature i.e., temperatures increase in the summer and de-crease during the winter. Dissolved oxygen (DO) had the opposite seasonal trend of temperature with a decrease in DO in the summer months and an increase in the winter months. Specific conductivity (SC), total organic carbon (TOC), turbidity, and total suspended solids (TSS) were influenced both by storm events, especially SC during the first storm runoff, and the irrigation season. Concentrations tended to spike during storm events, but remain at a lower but still elevated level during the irrigation season. Preliminary Assessment of Potential Beneficial Use Concerns: Potential impacts to key beneficial uses were evaluated by using selected indicators and comparing results against published water quality goals, targets and/or guidelines as follows:

• Drinking Water (SC, TOC, Nitrate, trace elements (arsenic, cadmium, copper, mercury, nickel, lead and zinc) and E. coli)

• Aquatic Life (pH, temperature, DO, turbidity, trace elements (cadmium, copper, nickel, arsenic, lead, zinc, and mercury), chloride and water column toxicity)

• Irrigation water supply (SC, and minerals (chloride, sodium and total dissolved solids)) • Recreation (E. coli)

In summary: Drinking Water/Municipal Supply: Total organic carbon was found to be elevated throughout the SJR Basin when compared to the 3.0 mg/L Bay Delta Authority’s guideline for water quality in the Sacra-mento-San Joaquin Delta (Delta). The entire SJR Basin drains into the southern portion of the Delta. Aquatic Life: Elevated temperatures during the spring and fall were a concern for fish passage along the SJR when compared to the Bay-Delta Authority target for the San Joaquin River at Vernalis of 20ºC from April 1–June 30 and from September 1–November 30. Higher levels of turbidity in the Westside basin were a concern but the current Basin Plan objective is based on background concentrations so it was difficult to evaluate for the existing ephemeral streams. Various levels of water column toxicity were reported sporadically on multiple occasions around the basin. A higher percentage of chronic tox-icity was reported as compared to acute toxicity. Samples for acute algae toxicity were collected less frequently but had a higher percentage (50 percent excluding Fremont Ford) of reduction and an in-crease in growth toxic events. For information on sediment toxicity around the basin see Sediment Toxicity Testing in the San Joaquin River Basin, October 2001 through September 2005 (http://www.waterboards.ca.gov/centralvalley/water_issues/water_quality_studies/surface_water_ambient_monitoring/swamp_water_quality_reports/index.shtml). Irrigation Water Supply: Specific conductance was found elevated above optimal irrigation water sup-ply concentrations throughout most of the SJR Basin when compared to the Water Quality Goal for Ag-riculture of 700 umhos/cm. In addition, individual samples were at times elevated above the Basin Plan objective for Vernalis of 700 umhos/cm April through August and 1000 umhos/cm September through March, although it should be noted that the objective is to be applied as a 30-day maximum running

average and was not intended to determine impairment using a single grab sample. The highest SC concentrations were measured within the Grasslands and Westside Basin. High salt concentrations can be attributed to a variety of components not limited to local geology/hydrology, importation and de-portation of water from and to different basins, waste products from urban, industrial, and agricultural practices—and is being evaluated separately under the Central Valley Salinity Alternatives for Long-Term Sustainability (CV-SALTS) project. Recreation: Occasional spikes of E. coli above the USEPA guideline of 235 MPN/100 ml (full contact recreation) were detected sporadically throughout the year, but the summer months were of particular concern due to the potential for recreational use increases for most of the waterways. Future Activities By the end of this study (2005), other Central Valley Water Board surface water monitoring efforts had expanded—notably the Irrigated Lands Regulatory Program (ILRP) and monitoring conducted under various grant efforts. The Central Valley Water Board SWAMP efforts became more focused on inter-nal and external monitoring coordination rather than continuing to maintain a separate monitoring strat-egy with shrinking resources. Some of these efforts are listed below.

• Development of the Central Valley Regional Board SWAMP website that documents monitoring activities supported by SWAMP and provides links to final reports and selected water quality data (http://www.waterboards.ca.gov/centralvalley/water_issues/water_quality_studies/surface_water_ambient_monitoring/index.shtml)

• Continued water quality monitoring support for the multi-agency Grassland Bypass Project (se-lenium control program)

• Leveraging funds with a separate USEPA project to continue development of a web-based monitoring directory designed to display active monitoring within the entire Central Valley (http://www.centralvalleymonitoring.org)

• Providing resources (staff and contract dollars) to facilitate development of a Regional Monitor-ing Program for the Sacramento-San Joaquin Delta

• Supporting Department of Water Resources staff to continue long-term trend monitoring at 41-sites in the northern Sacramento River Basin in exchange for the addition of selected constitu-ents of concern identified through Central Valley Regional Board efforts (TOC, nutrients, and toxicity) and realignment of 11-sites to correspond with sites utilized by the state-wide SWAMP sediment toxicity study

• Providing resources to insure ILRP water quality information is captured in the state-wide SWAMP master data base

• Developing a region-wide, long-term trend monitoring framework based on the 30-sites within the Central Valley that are part of the state-wide SWAMP contaminant trend monitoring effort.

• Providing assistance to other monitoring efforts to facilitate SWAMP comparability (e.g. review-ing quality assurance project plans)

Efforts related specifically to the elevated E. coli concentrations found within the SJR Basin as well as in other areas of the Central Valley as part of ILRP monitoring, are as follows:

• A survey of E. coli concentrations in local swimming holes before during and after a holiday weekend (coordinated with Central Valley watershed groups during both 2007 and 2008)

• A pilot bacteria source identification project with the University of California, Davis, in selected streams demonstrating elevated E. coli concentrations

• Continued, seasonal E. coli monitoring at 30-major integrator sites throughout the Central Val-ley.

3.0 INTRODUCTION The San Joaquin River Watershed Unit of the Central Valley Regional Water Quality Control Board (Central Valley Water Board) initiated a water quality monitoring program in October of 2000 as part of California Assembly Bill AB 982 (Chapter 495, Statutes of 1999). AB 982 focuses State Water Re-sources Control Board (State Water Board) efforts on developing a comprehensive ambient surface water quality monitoring program known as the Surface Water Ambient Monitoring Program (SWAMP). At the Central Valley Water Board, SWAMP is attempting to answer the following overarching question and related sub-questions.

What is/are the status and trends of ambient water quality in streams and rivers in the Sacramento River, San Joaquin River, and Tulare Lake Basins? --Are there spatial and temporal trends in water quality? --What is the location and extent of various levels of water quality? --Is there evidence of beneficial use impairment? (and over the long-term) --Is water quality getting better or worse? --Are Board programs (regulatory/non-regulatory) and management actions effective?

The SWAMP for the San Joaquin River (SJR) Basin (Figure 1) is built upon a monitoring framework developed as part of the agricultural subsurface drainage management program that focuses on sele-nium, salt and boron and has evolved since 1985 (discussed in more detail in section 4.0). The current SWAMP program contains 3 tiers. The first tier is a selection of sites along the main stem of the river, downstream of major inflows. The second tier is a series of sites representing inflows from specific sub-watersheds into the main stem of the river (drainage basin inflows component). These first two tiers consist of long term trend sites where monitoring is conducted weekly to monthly, depending on site and constituent. The final tier, the Intensive Basin Monitoring Program (IBP), is a more detailed, yearlong survey of the water quality within each of six sub-watersheds once every 5-years. Each of these sub-basins included water bodies with similar hydrologies, geologies, management issues, land use and land cover. The sixth basin, the southern Sacramento – San Joaquin Delta (South Delta), has not been included as part of the rotation due to the extensive monitoring and modeling already conducted by other agencies. A detailed discussion of the design of the 3-tier monitoring program is presented in section 6.2. This study focuses on the results for the first two tiers of the effort, the main stem San Joaquin River and inflows from sub-watersheds, between October 2000 and September 2005. Prior to initial water quality sampling, state, federal, and local agencies as well as known watershed groups were surveyed to identify current monitoring efforts and local concerns. These contacts included but were not limited to the Department of Water Resources, Department of Fish and Game, University of California, US Geological Survey, US Environmental Protection Agency, US Fish and Wildlife Service, Natural Re-sources Conservation Service, CalFed, San Luis Delta-Mendota Water Authority, Grassland Area Far-mers, local Resource Conservation Districts, and groups receiving water quality improvement bond grants.

Concerns were varied, but most consistently included potential impacts to aquatic life and recreation, in particular concerns with temperature, sedimentation, selenium, off-site movement of pesticides, and pathogens, with additional concerns of irrigation supply (elevated salt) and drinking water (elevated to-tal organic carbon). The final sampling design incorporated the survey findings as funding permitted. At a minimum, each site was analyzed for standard field measurements (SC, pH, temperature, turbidity, and DO) as well as total coliform and E. coli. Monthly photo documentation was taken at each site. Sampling expanded to include total organic carbon, total suspended sediments, trace elements (arse-nic, copper, chromium, lead, nickel, zinc, selenium, molybdenum, and mercury), biochemical oxygen demand, mineral data (chloride, sulfate, calcium, magnesium, total dissolved solids, carbonate, bicar-bonate, total alkalinity and sodium) and water column toxicity when additional funding was available. Data gathered over the five year period provides information on the spatial and temporal trends in water quality and preliminary indications on potential beneficial use impairments. Key beneficial uses evalu-ated and the indicators utilized are listed below.

• Drinking Water (Salt/Specific Conductance, Total Organic Carbon, Trace Elements, Nu-

trients, E. coli) • Aquatic Life (Toxicity, Temperature, Dissolved Oxygen, Trace Elements, Ammonia, pH) • Recreation (E. coli) • Irrigation Supply (Salt/Specific Conductance)

Details for overall SWAMP monitoring objectives and indicators, as well as data for expanded sub-basin monitoring and the selenium control program, can be found on the Central Valley Regional Water Quality Control Board SWAMP website at: http://www.swrcb.ca.gov/centralvalley/water_issues/water_quality_studies/surface_water_ambient_monitoring/sjr_swamp.shtml Since 2003, all data collected as part of the San Joaquin River SWAMP effort that met quality assur-ance requirements, has been posted annually at the above website.

Figure 1: San Joaquin River Basin 4.0 BACKGROUND

In 1985, an extensive water quality survey to evaluate the impacts of agricultural drainage on the lower San Joaquin River (SJR) was initiated. Although a number of issues of concern were identified, salt, boron and selenium impacts were the priority and a resulting multi-agency water quality monitoring pro-gram was created focusing its limited resources on evaluating these constituents. The area has since been the focus of the Region’s subsurface agricultural drainage program and considerable staff effort and resources have been directed to the effort of developing a comprehensive monitoring program, en-suring stakeholder involvement, and adopting Basin Plan Amendments and Waste Discharge Require-ments in order to develop a workable and comprehensive selenium control program. The compliance monitoring portion of this effort is the responsibility of the Data Collection and Report-ing Team (DCRT) whose members include representatives from the US EPA, US Geological Survey, US Bureau of Reclamation, US Fish and Wildlife Service, CA Department of Fish and Game, Central Valley Water Board, and Grassland Area Farmers. The DCRT monitoring program evaluates selenium concentrations, loading, and potential impacts in water, sediment, and biota. Water quality analyses for selenium salt and boron are conducted at nine sites within the Grassland Watershed and seven sites along the main stem of the SJR. Grab samples are collected weekly, with daily composites also col-lected at two key sites: the consolidated agricultural subsurface drainage discharge point on the San

Luis Drain; and at Crows Landing on the SJR. (See Grassland Bypass Program on the Central Valley Regional Board SWAMP website for more detailed information.) The SJR SWAMP program was built upon this established framework. Basin priorities include maintaining the Grassland Bypass Program and expanding it to facilitate real-time monitoring activities. Other issues of concern include: aquatic toxicity from waterborne pesticides; aquatic life impacts from pesticides in bed sediment; habitat impacts from sedimentation; elevated nu-trient and BOD levels; pathogens; elevated temperatures; impacts from abandoned mines, timber har-vesting and grazing; and establishing baseline condition in rural Coastal Range streams in areas slated for future urban development. 5.0 STUDY AREA 5.1 San Joaquin River Hydrology The San Joaquin River (SJR) is the principal drainage artery of the San Joaquin Valley. The basin covers 17,720 square miles (CVRWQCB, 1998) and yields an average annual surface runoff of about 1.6 million acre-feet. The SJR basin drains the portion of the Central Valley south of the Sacramento-San Joaquin Delta and north of the Tulare Lake Basin. The lower Basin (below Millerton Reservoir) has had a highly managed hydrology since implementation of the Central Valley Project (CVP) in 1951. From the Sierra Nevada, the river channel drains west-ward to the Mendota Pool near the town of Mendota. As the river channel continues past the Mendota Pool it turns northward to narrow by the constrictions of the Merced River and Orestimba Creek alluvial fans. From there, the river channel makes its way north to the Sacramento-San Joaquin Delta and out to the Suisun Bay. Most of the flow released from Friant Dam is diverted into the Friant-Kern Canal, leaving the river chan-nel upstream of the Mendota Pool dry except during periods of wet weather flow and major snow melt, which was the case in early 2005. The majority of the water in the Mendota Pool has been transported from the Delta via the Delta Mendota Canal (DMC) for irrigation use and to replace water lost thru di-version of the upper SJR flows. The majority of that poorer quality (higher salinity) water is then dis-charged to irrigation supply channels along the west side of the river, while some flows are released to the main river channel and continue to Sack Dam. Remaining flows not diverted for agricultural use out of the main channel are then diverted at Sack Dam leaving flows in the lower San Joaquin River (below Sack Dam) mainly dependent on releases from upstream reservoirs, agricultural return flows, and groundwater seepage, although wetland releases and storm water run-off can have considerable im-pacts on the flows as well. During the irrigation season, the flows in the river between Sack Dam and Salt Slough consist largely of groundwater accretions. Salt Slough and Mud Slough (north) are the principal drainage arteries for the Grassland Sub-Basin and add significantly to the flows and waste loads in the SJR upstream of its confluence with the Merced River. Eastside discharges dominate flows in the SJR, as higher quality (lower salinity) water is released from reservoirs on the Merced, Tuolumne, and Stanislaus Rivers. Flows from the west side of the river basin are dominated by agricultural return flows since west side streams are ephemeral and their downstream channels are used to transport agricultural return flows to the main river channel (Steenson, et al., 1998)

The principal streams in the basin are the San Joaquin River and its larger tributaries: the Cosumnes, Mokelumne, Calaveras, Stanislaus, Tuolumne, Merced, Chowchilla, and Fresno Rivers which all drain the east side of the basin. Major land use along the San Joaquin Valley floor is agricultural, occupying approximately 2.0 million acres, representing approximately 23% of the irrigated acreage in California (DWR, 2001). Urban growth along the I-5 corridor between Fresno and Stockton is rapidly converting historical agricultural lands to urban areas. As more and more people choose to commute from the Central Valley to the Bay Area, the rapid conversion of land is leading to increasing potential for storm water and urban impacts to local waterways. Timber activities, grazing, abandoned mines, rural com-munities, and recreation can impact upper watershed areas (Graham, 2009). 5.2 San Joaquin River Sub-Basins To help characterize the SJR watershed and develop a monitoring program targeting specific problems affecting water quality, the watershed was broken into six smaller sub-basins bound by the Sierra Ne-vada Mountains or the Coastal Range and comprised of similar land use and drainage patterns (Figure 2). All of the agricultural-dominated and constructed water bodies within each of the sub-basins have been identified (Chilcott, 1992), as well as the potential water quality concerns and major representa-tive discharges to the lower SJR. These sub-basins are similar to and based on, Total Maximum Daily Load (TMDL) efforts for salinity and boron in the lower SJR.

1. The Northeast Basin consists of the Cosumnes, Mokelumne, and Calaveras River Water-sheds, providing a combined drainage of 4,360 square miles.

2. The Eastside Basin contains the three largest SJR tributaries, in terms of flow: the Merced,

Stanislaus, and Tuolumne River Watersheds, along with the Farmington Drainage Basin and the lower Valley Floor Drainage Area, which drain directly to the SJR. The Eastside Basin is approximately 6,091 square miles.

3. The Southeast Basin is approximately 4,338 square miles and reaches from the headwaters of

the SJR north to the watershed divide between Bear Creek and the Merced River in Merced County.

4. The Westside Basin encompasses the watersheds of the creeks draining the eastern slope of

the Coast Range from the Orestimba watershed in the south to the Lone Tree Creek in the north. The Westside Basin is approximately 670 square miles.

5. The Grasslands Basin is a valley floor sub-basin of the SJR Basin, south of the Orestimba wa-

tershed, covering approximately 1,360 square miles. This basin lies on the west side of the SJR in portions of Merced, San Benito, and Madera Counties.

6. The South Delta Basin covers approximately 677 square miles and includes creeks on the

northwest side of the SJR, as well as the southern portion of the Sacramento-San Joaquin Delta waterways down toward the confluence of the SJR and the Sacramento River. Waters inside the Delta boundaries are tidally influenced and typically higher in salinity than other surface wa-ter throughout the SJR Basin.

Figure 2: San Joaquin River Sub-Basins 6.0 SAMPLING PROGRAM 6.1 Program Objectives In keeping with the overall Central Valley Regional Board SWAMP goals of being able to answer water quality questions related to spatial and temporal trends as well as whether or not there is evidence of beneficial use impairment, the following objectives were adopted for this effort:

1. Spatial and Temporal Trends a. Spatial includes the evaluation of the SJR moving progressively downstream as well as

comparisons between sub-basins b. Temporal includes seasonal variations and annual variations (by water year type)

2. Evaluation of Beneficial Use Protection a. Using selected indicators to determine whether there is evidence of impairment

3. Utilizing information gathered from the long-term trend sites within each sub-basin to help direct future monitoring program design within that sub-basin.

6.2 Design The SJR SWAMP program was designed as a trend-monitoring program that used a tiered approach. By using a tiered approach the SJR SWAMP program was able to adjust sampling constituents and monitoring frequencies to coincide with the year-to-year fluctuations in funding, as well as adjust for time delays associated with contracting to analytical laboratories. The use of available funds was then prioritized based on these tiers and the objectives of the program. This design resulted in less interrup-tion to monitoring activities that were considered higher priority for the program. Creating a tiered moni-toring design and selecting long-term sites and constituents also allows for the monitoring data to be evaluated over different water year types and facilitates assessment of implementation efforts going on throughout the valley. Monitoring sites for this program were selected from information gathered through existing monitoring efforts, historic data sets, the Inland Surface Waters Plan (Chilcott, J.,1992), the report Water Diversion and Discharge Points Along the San Joaquin River (James, E. W., et al.,1989), and reconnaissance done by Regional Board staff prior to initiation of any monitoring ef-forts. The first tier of the program is the Main Stem Program. In that program, eight sites were selected along the lower section of the SJR and monitored on a daily, weekly, monthly, or quarterly basis, depending on the constituent. Those sites were selected as long-term sites and are located downstream of major influences to the river. Those sites were the most important to the program since they represent the “bottom” of the system and could show potential changes to the river over time. Many of the sites se-lected were already being monitored as part of the Grassland Bypass Program (multi-agency selenium control effort), so coordination with those monitoring and data management efforts was incorporated. The second tier of the program is the Sub-Basin Program. The Sub-Basin Program moved the monitor-ing away from the main stem of the SJR and up into lower sections of the valley floor. In this program, 29 sites were selected as long-term trend sites representing the main inflows to the SJR from each of six sub-basins. The third tier, the Intensive Basin Program, was not directly part of the trend monitoring, but rather fo-cused on a 5-year rotational approach. This program contained approximately 20 sites per sub-basin, in addition to sites already part of the Sub-Basin Program, and focused solely on one sub-basin at a time. Sites selected within a sub-basin were monitored for one year, with the intent to rotate through the sub-basins once every 5 years.

To evaluate potential impact to beneficial uses, indicators were chosen for five broad beneficial uses: drinking water; recreation (swimming); aquatic life; irrigation; and waterfowl. The choice of indicators came from an evaluation of USEPA EPIC indicators (USEPA, 2003), water quality objectives and goals, and the fact that many of the indicators monitored as part of the SJR SWAMP efforts support high prior-ity region-wide program assessments as listed in the 2005 Triennial Review of the Water Quality Con-trol Plan for the Sacramento River and San Joaquin River Basins. Regional programs utilizing SJR SWAMP monitoring data include: Drinking Water Policy, Water Quality Objectives for Bacteria Indica-tors, Salinity and Boron TMDL, Central Valley Salinity Policy Development, Erosion/Sediment guide-lines, and SJR Dissolved Oxygen TMDL. In general, the first five years of the program were set-up to continually monitor sites on the SJR as part of the main stem program on a weekly basis, monthly for certain constituents, with the Sub-Basin sites being monitored on a monthly basis. The remaining funding was utilized in the Intensive Basin Pro-

gram. At the end of Water Year 2002 (i.e., 30 September 2002), a preliminary evaluation of the data collected as part of the first two years of the program was done and showed that the monthly monitor-ing frequency for nutrients, trace metals, minerals and TSS was not sufficient to develop useful trend information due to insufficient funding. Those analyses were then dropped from the program for a ma-jority of the sites (mainly the Sub-Basin sites). Table 1 lists the monitoring sites and sampling frequen-cies associated with the constituents monitored for each site. As funding permitted, samples were collected for: total suspended solids (TSS); total organic carbon (TOC); total coliform; E. coli; nutrients, including nitrate, nitrate-N, total kjeldahl nitrogen (TKN), ammo-nia, phosphorus, ortho-phosphate, and potassium; biochemical oxygen demand (5 and 10 day); chlo-ride; sulfate; calcium; magnesium; total dissolved solids (TDS); carbonate; bicarbonate; total alkalinity; sodium; water column toxicity [Pimephales promelas (P. promelas), Ceriodaphnia dubia (C. dubia), Se-lenastrum capriconutum (algae)]; hardness; arsenic; cadmium; chromium; copper; lead; nickel; zinc; and mercury. Figure 3 displays the distribution of the sites within the SJR Basin.

6.3 Sampling Procedures All samples were measured and collected in compliance with the Agricultural Subsurface Drainage Program Procedures Manual (Chilcott, et al., 1996) and the Quality Assurance Program Plan for the State of California’s Surface Water Ambient Monitoring Program “SWAMP” (SWRCB, 2002). Field measurements for temperature, specific conductance, pH, dissolved oxygen and turbidity were taken using one of three meters; Myron 6P Ultra Meter II (temp, SC, and pH only, Oct 2000- July 2001) Yellow Springs Instrument (YSI) 600 XLM Sonde (no turbidity), or a YSI 6600 Sonde (turbidity). All YSI readings were read from YSI 650 data logger. Clean sample containers were rinsed three times with ambient water prior to grab sample collection, except for sample containers that were pre-acidified (ammonia and TOC) or contained other neutraliz-ing agents (sodium thiosulfate for total coliform and E. coli). Water for pre-acidified samples was col-lected in a stainless steel cup or a sample bottle that was being collected for a separate constituent at the same site and poured into the sample container. All samples were kept at 4 degrees Celsius by storing them on ice after collection and during transport and in a refrigerator while in-house. Appendix H lists the laboratories, detection levels, holding times and acceptable recoveries for the pa-rameters monitored. 7.0 QUALITY ASSURANCE AND QUALITY CONTROL All quality assurance (QA) and quality control (QC) log-books for the constituents analyzed by outside laboratories were maintained by the Regional Board contract manager or their designee. QA/QC re-cords for bacteria analysis and equipment maintenance are recorded in the respective QA/QC log-books, found in the Central Valley Water Board laboratory where samples were analyzed. At a minimum, field sampling equipment was calibrated as per manufacturer’s instructions at the start and end of each sampling event and/or after 10-15 sites. If it was found that calibrations were off, the instruments were recalibrated and if needed, measurements re-taken. Field and handling contamination was evaluated by submitting blind travel blanks on a monthly basis, and on each run for bacteria monitoring. Travel blank samples traveled through the sampling run, and were processed with the sample set. For most constituents, the travel blank consisted of a sample of de-ionized (DI) water that was produced at the Central Valley Water Board laboratory. For bacteria monitoring, the travel blanks were prepared by the Department of Plant Sciences, University of Califor-nia Davis (UC Davis). After thorough discussion with UC Davis, the travel blanks were initially prepara-tions of boiled deionized water and NaCl, which was then switched to Type II water in July 2002, and ultimately, phosphate buffered saline was added to the Type II water travel blanks at the end of WY 2005. For toxicity monitoring, Sierra Foothill Labs, Inc provided de-mineralized water (DMW) to be used for travel blanks. All data sets used for this report had travel blank results that fell below the ana-lytical detection limits for the elements of concern. Consistency in sample collection and analysis was evaluated by collecting replicate samples for all samples needing laboratory analysis. The Central Valley Water Board San Joaquin River Watershed Unit uses a SWAMP compliant standard quality assurance procedure that includes 10% replicate sam-ples.

Precision and accuracy were evaluated using blind split and spiked samples. Blind split samples were collected at a 10% frequency for each sampling event by collecting the sample in a container double the normal sample volume and splitting that sample into two equal amounts for submittal to the analyz-ing laboratory. On a monthly basis, and when appropriate, half of the blind split samples were spiked with known concentrations of constituents to be analyzed. Comparing the spiked split to the back-ground split provided information on analytical accuracy. Comparing data from non-spiked splits pro-vided information on analytical precision. Potential contamination from the reagent grade nitric acid used to control pH was evaluated by submit-ting a deionized water matrix preserved with 1 mL of acid per 500 mL of sample, to the contract labora-tories at monthly intervals to be analyzed for the trace elements of concern. All reported recoveries for these acid check samples were below the analytical detection limit. Only data from sample sets whose blind QA/QC met specifications outlined in Appendix H have been included in this report. These specifications are consistent with the QAPP for this program. 8.0 PRECIPITATION AND FLOW: WATER YEARS 2000-2005 The San Joaquin River is the principal drainage artery of the San Joaquin Valley, draining the area south of the Sacramento-San Joaquin Delta and north of the Tulare Lake Basin, approximately 13,500 square miles (Graham, 2009; Steensen, et al., 1998). Precipitation varies throughout the SJR Water-shed and occurs as both rainfall and snow. Mean annual precipitation on the valley floor ranges from less than 5 inches in the south to 15 inches in the north. Average annual precipitation in the Sierra Ne-vada, mostly in the form of snow, ranges from about 20 inches in the lower foothills to more than 80 inches at some higher altitude sites. Precipitation in the Coast Ranges varies from less than 10 inches to more than 20 inches. As in the valley, precipitation in the Sierra Nevada and Coast Ranges in-creases from south to north (Dubrovsky, et al., 1998).

The San Joaquin River Index, as described in the Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Estuary is used to classify the water year type in the river basin based on runoff. The 60-20-20 Index includes five classifications: wet, above normal, be-low normal, dry, and critical, based on millions of acre-feet of calculated unimpaired flow. (SWRCB, 1995)

A Water Year begins 1 October and ends 30 September of the following year. Because of the timing of this study, October 2000 through September 2005, five full water years are represented. Table 2 lists the Water Year Classifications based on rainfall and snow totals in the SJR Watershed during the pro-ject.

Figure 7 displays the San Joaquin River Watershed Monthly Rainfall Data during the project. These sites represent precipitation throughout the basin and were chosen for their extensive reliable record. Figure 7: San Joaquin River Watershed Monthly Rainfall Data Water Year 2001-2005

(Data Source, DWR-California Data Exchange Center (CDEC)) 9.0 BENEFICIAL USES AND APPLICABLE WATER QUALITY OBJECTIVES AND GOALS One component of the Central Valley Water Boards SWAMP efforts is to evaluate ambient water quality to determine whether there is any indication that beneficial uses are being impacted. Information gath-ered during this study allowed analysis of a broad spectrum of water bodies at key integrator sites in order to determine existing quality at the site itself and allow some inference of the water quality within identified sub-basins. Potential beneficial uses applicable to each site monitored were identified using the designated listing from the Sacramento/San Joaquin Water Quality Control Plan (Basin Plan) (CVRWQCB, 1998). To evaluate potential impact, indicators were chosen for five broad beneficial uses: drinking water (salt, TOC, trace elements, nutrients, bacteria); aquatic life (pH, temperature, dis-solved oxygen, turbidity, and water column toxicity); irrigation water supply (salt); recreation (bacteria); and waterfowl (selenium). Selenium was not assessed in this report due to the in-depth analysis of the same data through the Grassland Bypass Project. Not all of the indicators could be monitored at each site, due to funding limitations, but at least one indicator for each beneficial use evaluated was included at each site for the study.

29

The following two sections highlight: 1) the beneficial uses that apply to each of the water bodies sam-pled; and 2) the objectives and goals that were utilized when evaluating results to determine whether there was any indication that water quality was not supporting a specific beneficial use.

9.1 Applicable Beneficial Uses In the SJR Basin, all natural water bodies have potential municipal and industrial supply designated through the statewide Sources of Drinking Water Policy (State Water Resources Control Board Resolu-tion No. 88-63). Other specific beneficial uses have been designated to individual water bodies as well as the San Joaquin River/Sacramento-San Joaquin Delta—to which the entire SJR Basin drains. The beneficial uses of any specifically identified water body generally apply to its tributary streams. The applicable beneficial uses for each sampling site have been summarized in Table 4, under the general headings of Drinking Water, Recreation Use, Irrigation Supply and Aquatic Life. Table 4 indi-cates whether the use has been specifically designated or is being applied as a tributary. Appendix Q3 provides more detail on the subcategories of use that have been specifically designated in the Sacra-mento-San Joaquin Basin Plan. 9.2 Applicable Water Quality Objectives and Goals Water quality information collected during this study was evaluated using water quality objectives adopted in the Sacramento River and San Joaquin River Basin Plan (CVRWQCB, 1998), a compilation of water quality goals identified by state and federal agencies (Marshack, 2003) and targets developed by the Bay-Delta Authority (CFBDP, 2000). The Basin Plan objectives are enforceable criteria that are linked to protecting designated beneficial uses such as domestic, municipal, agricultural and industrial supply, recreation, and preservation and enhancement of fish, wildlife and other aquatic resources. These objectives are both numeric and narrative and may be specific to certain reaches of various wa-ter bodies or apply to entire basins. The water quality goals are scientifically defensible numeric criteria developed by diverse agencies to protect specific uses; primarily aquatic life, drinking water, and irrigation supply. In many cases, the goals are national guidelines. These goals may be used to determine compliance with some of the nar-rative Basin Plan objectives (e.g. toxicity). Both the objectives and the goals apply to the indicators used to evaluate beneficial use protection. A summary of the general groups of indicators that can be utilized to evaluate a beneficial use and the most limiting use (e.g. if the objective/goal is met for that use than it would be met for the remaining uses) is listed in Table 3. Appendix Q1 lists the applicable Basin Plan objectives for this study. For turbidity, pH, temperature, and total suspended sediment, the listed objectives refer to changes impacting “normal” and “natural” conditions. For this study, natural conditions have been assumed to be conditions at the furthest up-stream sampling location or upstream of a specific discharge. Appendix Q1 also includes targets iden-tified by the Bay-Delta Authority (a joint State and Federal agency) to protect fish passage (temperatures not to exceed 20-degrees Celsius) and drinking water (total organic carbon to remain below 3.0-mg/L). Appendix Q2 shows the applicable goals sorted by generalized beneficial uses.

10.0 RESULTS 10.1 Result Summaries All data collected is presented in Appendices A-G. Summary tables of the information were created using the appendices and indicate the number of samples taken, minimum and maximum values ob-served, mean, geo mean, median, quartile 1 and quartile 3 for all of the sites sampled. These summary tables also include sub-basin summaries. These sub-basin summaries do not include the San Luis Drain and New Jerusalem Drain—two sites unique to the basin since they represent shallow groundwa-ter/sub-surface drainage and not typical surface flows. Table 5a provides a summary of the field tem-perature, specific conductance (SC) and pH. Table 5b lists summary results for dissolved oxygen (DO), turbidity and total suspended solids (TSS). Table 5c lists total organic carbon (TOC), total coli-form and E. coli. Table 5d summarizes nitrate, nitrate-N, and total kjeldahl nitrogen. Table 5e lists ammonia as N, phosphorus and ortho-phosphate as P. Table 5f summarizes potassium, biochemical oxygen demand (5-day and 10-day). Table 5g summarizes chloride, sulfate, and calcium. Table 5h provides summaries of magnesium, total dissolved solids (TDS), and carbonate. Table 5i lists bicar-bonate, total alkalinity and sodium. Sample collection for metals and toxicity were limited, so results have been provided in the appendices and are evaluated in the discussion section of the report. A toxic event summary table (Table 6) of the toxicity data collected was created by defining a toxic event as statistically significant and at least a 20% difference from the control. Table 6 shows toxic events for acute fathead minnows, acute Ceriodaphnia dubia, acute algae, chronic fathead minnow and chronic Ceriodaphnia dubia.

12.0 DISCUSSION The main stem river and sub-basin tiers of the SJR SWAMP effort have two main objectives: evaluate overall water quality, both temporally and spatially, and assess whether there is any indication that beneficial uses are not being protected. A third adaptive objective is to utilize the information gathered at the long-term sites for the sub-basins to help design future monitoring efforts within that sub-basin. This section discusses the results in the context of those objectives. This five-year study covered: three dry water years, one below normal water year, and one wet year. The final year of this study was one of the wettest years on record. The overall water year effects as well as seasonal effects between storm, snowmelt, irrigation and dry seasons are depicted in a series of paired line graphs for each constituent specifically evaluated: one graph for the SJR sites and one for the Northeast Basin sites (representing temporal trends within sub-basins). If trends within one of the other sub-basins differed greatly from the Northeast Basin, a separate figure was included within the discussion. Similarly, spatial trends were depicted using paired box and whisker figures: one figure showing sum-mary information for SJR sites moving downstream; and the second figure showing summary informa-tion for each sub-basin, also moving downstream, as well as summary information for the San Luis Drain and New Jerusalem Drain which represent shallow groundwater within the Grassland and Delta sub-basins, respectively. Drainage basin sites were selected as being representative of the major flows to the SJR from each basin. While graphical summary information for each sub-basin was not included within this section of the report, the figures are available in Appendix R. Wherever possible, water quality objectives, guidelines and/or targets have been noted on the figures to help put the results in context. Evaluation of the constituents and their potential impacts on the beneficial uses is evaluated in section 12.2. The data collected was utilized in combination with other available data sets during the development of the draft 2009 Clean Water Act Section 305(b) and 303(d) Integrated Report for the Central Valley Region that identifies specific beneficial use impair-ments for water body segments throughout the Central Valley. A summary of potential concerns for each sub-basin that may aid future monitoring design is included in the summary/conclusion of this re-port. All the sites are located relatively close together in the lower reaches of the individual sub-basin prior to discharge into the SJR, therefore have similar localized land use influences, the most notable being dominance by agricultural return flows during the irrigation season. Source water does vary widely, from Sierra snow melt to imports from the Sacramento-San Joaquin Delta and may also include storm water, wetland drainage, operational spill, and ground water discharge. 12.1 Temporal and Spatial Trends 12.1.1 TEMPERATURE Temperature was measured in degrees Celsius and ranged from 1.9 – 32.8 throughout the Basin dur-ing the 5-year study. A very consistent seasonal oscillation was seen at all the sites and tracked those within the Northeast Basin. The lowest temperatures were seen in January around 5ºC with a gradual climb to its peak in July around 25ºC (Figures 8 and 9). The majority of the South Delta Basin sites showed the same seasonal oscillation as the Northeast Ba-sin except New Jerusalem Drain. The New Jerusalem Tile Drain had relatively higher temperatures and shorter amplitude oscillations then the rest of the South Delta Basin sites. Through dry and wet years the temperature showed no significant differences.

No significant spatial differences were observed either moving upstream to downstream along the main stem of the SJR, nor between sub-basins. Figures 10 and 11 show the relatively consistent ranges in temperature within the basins and SJR, respectively. Figure 8: San Joaquin River Northeast Basin Temperature WY01-WY05

12.1.2 SPECIFIC CONDUCTANCE Specific conductance (SC) values ranged from 8.0 - 5,960 µmhos/cm across the SJR Basin. Seasonal patterns in SC were not as clearly defined as for temperature. In general, SC tended to decrease dur-ing the dry season (September through November), sometimes showing a peak during the first storm runoff and then decreasing until the irrigation season began in May/June with the highest concentra-tions recorded during the irrigation season. Exceptions to this rule include water bodies that receive wetland releases in early spring (Grasslands sub-Basin and SJR), where additional spikes are evident (Steenson, et al., 1998). This pattern is depicted in Figures 12 and 13, the NE Basin and SJR sites, respectively. In addition, overall SC values appeared to decrease during wet WY 2005, although the seasonal trend patterns remained similar. Temporal anomalies within each sub-basin are discussed below. Northeast Basin: The Northeast basin was managed from April through October by diverting water into different channels to supply agricultural use. Each growing season, Bear Creek, which naturally would be dry for the summer months like the Cosumnes River, was dominated by agricultural supply that was diverted from the Mokelumne River. This change in water type was observed each year when the Bear Creek SC dropped to about 50 µmhos/cm, the approximate year round SC of the Mokelumne River. Pixley Slough is also dominated by agricultural supply during the growing season and seemed to follow the same trend, but it wasn’t as dramatic as Bear Creek. The one notable difference between the dif-ferent water year types was that Bear Creek was about 100 µmhos/cm higher during winter months of a wet year than during the dry years. Eastside Basin: French Camp Slough and Lone Tree Creek followed the Northeast Basin’s Bear Creek trend with having lower concentrations of SC in the growing season and higher concentrations during the winter. The Harding Drain also followed this same trend of higher levels during the winter months and lower levels during the agricultural season but the levels of SC are much higher than any of the other agricultural influenced sites in this basin (e.g. Turner Slough). The Eastside river sites were fairly consistent throughout the 5 years with Stanislaus River demonstrating little seasonal variability. The Tuolumne River is a little more sporadic, but always seemed to drop in April. The Merced River had the opposite trend when compared to Bear Creek in the Northeast Basin. Specific conductance levels on the Merced River went up during the growing season and down in the winter months. Southeast Basin: Bear Creek in the Southeast Basin, like the Eastside rivers, didn’t fluctuate drastically and showed sporadic levels similar to the Tuolumne River although no seasonal trends seemed to be evident in Bear Creek. Dramatic changes were identified in Deep Slough, similar to the Harding Drain, but seemed to drop drastically in the 2005 wet year when compared to the previous consecutive dry years. South Delta Basin: The South Delta Basin’s SC levels were mostly above 500 µmhos/cm unlike the Northeast basin where all the samples were below 500 µmhos/cm. The New Jerusalem Drain (dis-charging shallow groundwater from the basin) reported consistently high SC levels all year long fluctu-ating around 2500 µmhos/cm with no noticeable consistent trend. Mountain House Creek, an ephemeral stream which historically received agricultural tail water, was dry for about half of the sampling period through 2003. In 2004, the site was removed from the sampling program due to the rapid community development with about 43,500 residents settling on the land ad-jacent to and surrounding the creek (Weston, 2009). The change in localized land use included rerout-ing storm water runoff into a collection system and resulted in continuous dry conditions for the original creek bed. During sampling conducted prior to the development (from December 2000 through Febru-ary 2001), Mountain House Creek had seasonally stable SC values (typically below 1000 umhos/cm), similar to New Jerusalem Drain.

Old River is dominated by estuary flow characteristics. Old River followed the same SC characteristics of the Tuolumne River on the Eastside Basin fluctuating throughout the year with lower SC levels measured during the 2005 wet year, but overall Old River fluctuated at a higher SC level. Tom Payne Slough fluctuated like the Harding Drain with drastic fluctuations between summer and win-ter months. Like the Harding Drain, Tom Payne Slough has influences other than agricultural which include NPDES discharges and tidal influences. However, similar to the rest of the Delta Basin sites, Tom Payne Slough generally reported higher SC concentrations than the Harding Drain. Westside Basin: Like the Delta Basin, the Westside Basin had higher SC levels than the Northeast Ba-sin. Westside sites Del Puerto Creek, Grayson Drain, Ingram Creek, Hospital Creek and Orestimba Creek are ephemeral streams dominated by irrigation return flows. Ingram Creek had the largest SC fluctuations during the irrigation season and was the only creek to have very high distinct SC values during the winter months. Orestimba Creek receives operational spill from the CCID (Central California Irrigation District) Main Canal which could result in dilution and may have contributed to the narrower range of fluctuation in SC levels when compared to the other Westside sites. Grassland Basin: The Grassland Sites had higher values of SC than most of the other basin sites. The San Luis Drain represents shallow groundwater discharge from approximately 97,000-acres (Bureau of Reclamation, 1995) of irrigated agriculture and affects SC values observed in Mud Slough (Figure 14). All the Grassland sites had an oscillating trend that peaked in March or April, which corresponds to both wetland releases and pre-irrigation runoff (Figure 14). The Grassland Basin is highly managed and does not demonstrate a significant difference between water year types aside from slightly lower SC values during the 2005 wet year. Spatially, the Northeast, Eastside and Southeast Basins had considerably lower levels of SC as com-pared to the South Delta, Westside, and Grassland Basins (Figure 15). The eastern basins draining the Sierra watershed begin with less saline water than those dependent on imports from the Delta. Al-though each basin had unique seasonal and temporal trends, during the 2005 wet water year there was a slight decrease in the SC values at most sites. Inflows from the various sub-basins appear to have a dramatic overall effect on the SJR as the inflows progressively reach the river (Figures 15 and 16). As we travel downstream, Southeast Basin flows tend to be trapped at Sack Dam and diverted. The SJR at Lander Avenue is dominated by ground wa-ter accretion for much of the year and provides a background elevated SC in the river. High SC levels in Salt Slough and Mud Slough, resulting from wetland as well as surface and subsurface agricultural drainage, increase the already elevated river levels. Starting immediately downstream of the Hills Ferry site, the Eastside tributaries (Merced, Tuolumne and Stanislaus Rivers) begin to influence SC levels along the SJR and gradually lower them resulting in levels observed at Vernalis that are just slightly higher than at Sack Dam.

12.1.3 MEASURED pH The pH values ranged from 5.4 – 10.1 across the basin. Mean values in the SJR ranged from 7.6 to 7.9 units. Few levels dropped below 6.5 pH units, though several appeared to seasonally exceed 7.5 units—during the irrigation season in the SJR and during the storm season in the Northeast Basin. Seasonal variability appeared reduced during wet WY 2005. Occasional spikes, both high and low, were seen throughout the sampling season (Figures 17 and 18). Most of the basins appeared to follow the general trend of the Northeast Basin, with the majority of pH values falling between 7 and 8 units. The Cosumnes River had a wider range of variability compared to the Mokelumne River and the other sites. The variability seen in the Cosumnes River seemed to be most pronounced following its natural annual dry period. The Westside Basin showed similar occa-sional fluctuations as the Northeast Basin but reported slightly higher concentrations ranging most fre-quently from 7.7 to 8.4 pH units. The Grassland Basin and the SJR sites were sampled more frequently (weekly) and demonstrated clear seasonal fluctuations with the exception of Salt Slough. The pH values found in the river and Grasslands would peak in July and drop around January, following the same trend seen in temperature results. During the 2005 wet water year, there was no peak in July which can probably be attributed to the greater flows seen during this time when compared to the previous dry years. Spatially, the Northeast, Eastside and Southeast basins reported slightly lower pH than the Westside and Grassland Basin’s (Figure 19). Those differences did not appear to impact the SJR, as there does not appear to be any distinct difference in pH moving downstream (Figure 20). All of the river sites are approximately the same range and like the basin sites show occasional fluctuations, with the smallest minimums and greatest maximums recorded at the furthest upstream (SJR at Sack Dam) and down-stream (SJR at Airport) sites.

12.1.4 DISSOLVED OXYGEN Dissolved oxygen is well known to have clear diurnal patterns which make grab sampling for trend ana-lyses challenging, even if collecting at the same time each day. It was interesting to note that during this sampling effort, the variability in collecting weekly samples (Figure 21—the San Joaquin River sites) almost masked the seasonal pattern that was more evident with monthly sample collection (Fig-ure 22—the Northeast Basin). In general, dissolved oxygen (DO) had a defined seasonal oscillation that is opposite of temperature. Dissolved oxygen concentrations tended to increase from October through April and decrease from May through September. The same pattern was evident during wet WY 2005, but the range in concentrations was much less. Only discharge from the San Luis and New Jerusalem Drains (both carrying shallow groundwater from their respective basins) did not appear to have significant seasonal patterns with concentrations remaining near 10 mg/L at both sites. Spatially, the Grassland and Westside Basins had consistently higher DO levels than the Northeast Basin and non-river Eastside Basin sites, with the non-river sites of French Camp Slough and Lone Tree Creek reporting the lowest recorded DO concentration (0.4 mg/L) in May 2002 and October 2004, respectively. The highest values were observed in the San Luis Drain which had a mean of 12.5 mg/L. The river itself did not demonstrate much spatial variability with the majority of the reported values tracking near 10 mg/L DO. The greatest overall site variability was noted at Lander Avenue, with high and low spikes that did not tend to track the remaining sites. The two lowest overall DO concentrations of 0.6-mg/L and 1.3-mg/L were recorded at Sack Dam and at Airport Way, the most upstream and most downstream sites, respectively

12.1.5 TURBIDITY Turbidity findings are based on samples taken from July 2002 through June 2004, which encompasses portions of three water years: WY2001 (dry); WY2002 (dry); and WY2003 (below normal). The limited data set does not appear to demonstrate specific seasonal trends reporting spikes and dips throughout the year with individual sites both in the Northeast Basin and along the SJR. However, most sites did demonstrate a spike in turbidity that corresponded to a winter storm in December 2002 (Figures 23 and 24). Most of the sites appeared to show the greatest fluctuation in concentrations during the WY2003 irrigation season (April through August 2003), with a number of high values recorded. Mud Slough (north) and Salt Slough within the Grassland Sub-Basin also demonstrated increases during wetland flood-up (September) and wetland releases (April). Both these water bodies receive drainage from wet-land habitat. These spikes were echoed in data for the San Joaquin River at Hills Ferry and at Fremont Ford—sites downstream of the Grasslands’ inflows but upstream of the first Eastside river inflow (the Merced River). Spatially, the Westside and Grassland Basins reported higher overall turbidity than basins draining the Sierra or the Delta. The exception was the Southeast Basin which had overall turbidity concentrations similar to the Grassland Basin. Both basins receive wetland drainage. The Westside basin consists of ephemeral streams dominated by agricultural discharges and reported greater and more frequent fluctuations in turbidity then the rest of the Basins (Figure 25). Storm water inflows and run-off were the most evident in Salado Creek during the 2002 storm event resulting in a turbidity value of 1990 NTU. The differences in the Basins are clearly shown by how they affect the SJR (Figure 26). Figure 27 pro-vides an example of the impact that sub-basin inflow can have on the SJR during a pre-irrigation and wetland drainage period (23 – 27 March 2003). The dashed pink line representing a 5% increase over “background” Lander Avenue concentrations, helps visualize Westside inflows to the river increasing turbidity until the main Eastside rivers provide fresh water and bring the turbidity back down to slightly above SJR at Lander levels. Figure 28 is an example during the winter storm event (18 – 19 December 2002). The Westside influences again raise the turbidity above “background” Lander Avenue concen-trations until after Hills Ferry when the Eastside Rivers enter the system. Figure 28 shows that during a winter storm event, turbidity in the SJR at Lander is greater than the turbidity downstream at Vernalis—opposite the finding during early spring.

12.1.6 TOTAL SUSPENDED SOLIDS Total suspended solids (TSS) samples were generally collected weekly at the SJR main stem sites (ex-cept during WY04 where no TSS samples were collected due to funding shortfalls) and monthly during WY01 at all the drainage basin sites. TSS was also collected monthly during the irrigation season (June thru August) in WY05 at the Westside Basin sites. Elevated levels in both the SJR and Basins between January and April 2001 correspond to a series of significant (greater than 1-inch) rainfall events. The TSS begins to climb again at the beginning of the irrigation season (June) and remain ele-vated, but concentrations remained lower than the spikes seen during storm events. For the SJR sites, there was no obvious difference in concentrations during wet WY 2005, except for an increased fre-quency of spikes during winter rainfall events (Figure 29). Figure 30 displays the TSS data available during the irrigation season (March thru September) during both WY01 and WY05 for the Westside Basin sites. The incomplete data sets indicate increasing con-centrations, particularly in Ingram and Hospital Creeks and Grayson Drain which show a number of spikes above 3,000 mg/L TSS. The variability in findings indicates the need for more continuous data sets during the irrigation season. Spatially, similar to turbidity, the Westside and Grassland Basins had higher concentrations of TSS when compared to the other Basins (Figure 31). Most of the larger waterways seemed to track consis-tently with the river sites downstream of their inflows. In particular, the highest overall levels of TSS in the SJR were recorded at Fremont Ford and Hills Ferry (Figure 32)—downstream of Grassland Basin and some Westside Basin inflows, but upstream of the Merced River and other Eastside Basin influ-ences. Overall concentrations in the SJR remained below 100-mg/L TSS with a median near 50-mg/L, as did all the sub-basins except the Westside. Although median Westside Basin TSS concentrations remained near 75-mg/L, 50% of the concentrations ranged between 40 mg/L and 345 mg/L. Some unique findings within selected sub-basins are noted below. Northeast Basin: Although similar in land use and size, the Cosumnes River TSS concentrations ap-peared to more directly track storm events when compared to the Mokelumne River (Figure 33). The one major difference between the basins is that flow from the Mokelumne River is regulated by Caman-che Reservoir. Reservoirs on other major rivers in the SJR Basin likely have similar buffering effects. Eastside Basin: Similar to turbidity, Turner Slough and Harding Drain had larger and more fluctuating TSS values than that of the rivers sites. Grassland Basin: The Discharge from SLD was monitored for TSS weekly through the Grassland By-pass Program. Flow in the drain is specifically regulated to minimize potential for bed sediment sus-pension and storm event influences. The TSS concentrations in the drain remained relatively constant just below 50-mg/L and did not reflect patterns noted in other Grassland waterbodies.

12.1.7 TOTAL ORGANIC CARBON Total organic carbon (TOC) samples were to be collected weekly at the SJR main stem sites and monthly at the drainage basin sites. Unfortunately, major gaps exist in the data due to both limited funding and sample quality control. Key gaps exist for the river sites during the winter storm periods (January thru March) of 2002, 2003 and 2004. Data for sites collected in the basin demonstrate the same gaps with the addition of no data between May 2003 and October 2004. The distinct data gaps make trend analyses difficult. In general, the major river sites appear less susceptible to random spikes in concentration and demon-strate elevated levels during winter storm events and the irrigation season. Using the Eastside Basin as an example (Figure 34) the river sites (Merced and Tuolumne Rivers) do not fluctuate as drastically as Turner Slough and Lone Tree Creek. Some of the spikes in TOC concentrations correspond to storm events, such as the spike seen in Lone Tree Creek in the winter of WY2005. Other spikes (Turner Slough in Dec 2000 and French Camp Slough in May 2002) don’t correspond to a large or first-flush storm event. The Cosumnes River was an exception to the other major river sites in that it did show a dramatic spike in June of 2001, which corresponds to a small rain event just before this ephemeral stretch of the river dried (Figure 35). At no other time did TOC concentrations rise as dras-tically at this site before the seasonal dry periods. Sites moving downstream along the SJR that receive wetland discharge (Lander Avenue, Fremont Ford and Hills Ferry) also show elevated concentrations during wetland releases in early spring. During wet WY05, TOC concentrations in the SJR tended to decrease after the final storms in April and did not show the same magnitude of increase during the irrigation season as was evident during previous dry years (Figure 36). Overall, total organic carbon values ranged from <1.0 mg/L at many of the sites to a maximum of 67 mg/L at Lone Tree Creek. Between the basins, the Grassland basin has a higher median TOC than all the other basins (Figure 37). The Northeast and Eastside river sites have the lowest concentration of TOC. The non-river sites for the rest of the basins have higher concentrations, fluctuations and high spikes of TOC. These spikes could be influenced by storm events, agricultural and wetland manage-ment practices. Some unique characteristics for selected basins are discussed below: South Delta Basin: The South Delta Basin on average had lower concentrations of TOC than the East-side Basin non-river sites. The New Jerusalem Drain had the lowest concentration of TOC throughout the sampling period. There was one large TOC spike found in the New Jerusalem Drain, Tom Payne Slough, and Old River between the end of August and October of 2001. No rainfall was measured dur-ing August 2001, with the first rains starting in September 2001. The early spike measured in TOC could have been attributed to agricultural influence with the later part being a combination of agricul-tural influence and storm flows. Westside Basin: Westside Basin TOC concentrations fluctuated like the Eastside Basin non-river sites, but without as large of spikes. In addition to spikes in June of 2001, the same distinct spike noted in the South Delta in October of 2001 also occurred in Westside water bodies—. The October 2001 spike corresponded to the first rains after a very dry summer. Grassland Basin: The Grassland Basin’s fluctuations looked very similar to the Westside Basin’s, with major spikes in the fall of 2001. Levels of TOC were typically higher early in the fall, when local flows also increase due to spill from the seasonal flooding of surrounding wetland habitat. Levels typically dropped after the initial week of wetland flood-up and prior to the first storm event. Concentrations of TOC during wet WY of 2005 for the Grassland basin were noticeably more stable than those measured during the dry WY of 2001.

Moving down the main stem of the SJR (Figure 38), Sack Dam had a median background concentra-tion of 3-mg/L TOC. The median TOC concentrations then peaks to 8-mg/L at the next downstream site (SJR at Lander) and progressively decreases until reaching the boundary of the Delta (Airport Way) with a median TOC back near 3-mg/L. The Lander Avenue site had the highest concentrations and most dramatic fluctuations of TOC along the SJR. Inflows from the sub-basins seem to contribute to the drop in concentration of TOC moving toward the Delta. Figure 34: San Joaquin River Eastside Basin Total Organic Carbon WY01-WY05

The analytical method used for bacteria analyses during this study (IDEXX) has a maximum detection limit of 2419.6 MPN/100ml and a minimum detection limit of 1 MPN/100ml, numbers which were used as the upper and lower boundaries for median concentration calculations and graphs. Results ranged from 52 MPN to >2419.6 MPN for total coliform and1.0 MPN to >2419.6 MPN for E.coli. Total coliform concentrations tended to exceed the maximum detection limits at most sites except dur-ing storm events—when the concentrations decreased rapidly. Figure 39 demonstrates the trend for the Northeast Basin. In contrast, the majority of E. coli concentrations (a subset of total coliform) were reported within the detectable ranges and showed sporadic spikes in concentration, some related to storm events and oth-ers related to dry periods. Figures 40 and 41 demonstrate the variability seen in the results for the Northeast Basin and SJR sites, respectively. A number of the E. coli spikes during the winter season occurred when the sample was collected during the first flush of a major storm series—at a time when the total coliform was still above reporting limits, with subsequent samples showing much lower con-centrations. Of particular note is that during WY02, sampling frequency at the Northeast Basin sites increased to twice a month as that watershed cycled into the rotational basin sampling schedule. The increased sampling related to an increase in the number of spikes reported at those sites. In addition, a greater number of elevated E. coli concentrations were detected in the SJR between January and June during wet WY05 when compared to previous water years. Spatially, total coliform appeared uniformly high throughout the SJR Basin and was normally above de-tection limits with lower concentrations mostly seen during high flow events. For E. coli, the Grassland and South Delta Basin had lower concentrations compared to the rest of the basins (Figure 42). The Westside Basin had a considerable increased number of E. coli spikes when compared to the rest of the basins as well as higher overall spikes during low flow time periods. Both the Westside and South-east Basins reported 50% of samples collected falling between 200 MPN/100ml and 1200 MPN/100ml—much higher than the remaining basins. The river itself had the highest median E. coli concentration (124 MPN/100ml) at the Hills Ferry site, just prior to inflow from the Eastside rivers. The Hills Ferry site also had the highest overall concentra-tions in the SJR, but the majority of samples remained well below 235 MPN/100ml (the US EPA guide-line for full contact recreation) (Figure 43). Some unique characteristics noted for selected sub-basins follow. Northeast Basin: The Northeast Basin’s total coliform stayed mostly at the maximum detection limit until higher flow events during which the levels dropped (Figure 39). Lower concentrations during high flow events were more pronounced for the river sites than Bear Creek and Pixley Slough. E. coli was mostly found to be around the lower level of detection and would spike upwards during lower flow events (Fig-ure 40). The river sites did not seem to spike as frequently as Bear Creek and Pixley Slough. E. coli in Bear Creek and Pixley Slough also spiked periodically during higher flow events. South Delta Basin: South Delta Basin bacteria concentrations had a similar trend to the Northeast Ba-sin, but overall E. coli had much lower concentrations. E. coli for the New Jerusalem Drain never went above 27 MPN/100ml, which is likely related to the fact that it is a collection system for shallow ground water (subsurface tile drainage). The two samples collect in Mountain House Creek prior to drainage diversion after urban conversion, were both very high with the lowest sample at 1046.0 MPN/100ml.

Westside Basin: The Westside Basin showed the same trend as the Northeast Basin river sites. E. coli found in the Westside Basin showed the greatest number of spikes throughout the whole year. Ores-timba Creek had the lowest number of samples above the detection limit for E. coli, but the second highest geometric mean. Grassland Basin: The Grassland Basin had lower E. coli levels, similar to the Delta Basin, with only two samples found above the detection limit. The discharge from SLD had the lowest levels of E. coli in the basin. The SLD also consists of subsurface tile drainage, similar to the New Jerusalem Drain, but for a larger area.

12.1.9 NUTRIENTS Nutrient samples were collected throughout the basin on a monthly basis through WY02 (excluding ni-trate-N and ammonia-N). At the end of fiscal year 02/03, an initial review of the data collected and a review of collaboration efforts with the Total Maximum Daily Load (TMDL) programs (specifically the TMDL for dissolved oxygen) were completed. With a redirection of the DO TMDL program to conduct continuous measurements at select sites and add additional monitoring for chlorophyll a, nutrient col-lection at most of the drainage basin sites was discontinued to avoid duplication of effort. The excep-tions were Mud Slough upstream of SLD, Discharge at SLD and Mud Slough (downstream) @ SLD which are monitored in conjunction with the Grassland Bypass Program, and continued collection at the SJR main stem sites of SJR @ Fremont Ford and SJR @ Crows Landing until December 2004. Much of the data for WY02 and the first half of WY03 was removed from the data set due to failed QA/QC. Most of the nutrients at sites within the SJR Basin had relatively low levels, with the exception of nitrate; however, the limited data set makes trend analyses difficult. Figure 44 depicts available SJR nitrate information for this program. From the information collected in WY01, nitrate increases during both the storm season (January thru March) and then again during the irrigation season. The available data mirrors portions of those trends in 2002 and 2003. Nitrate concentrations reported for the Northeast Basin were all below 6-mg/L, with little discernible trends during the single water year of data (WY01)(Figure 45). The Westside Basin reported higher overall concentrations and a distinct spike in Orestimba Creek during the storm season and spikes in Del Puerto during April (typically a pre-irrigation period) as well as June thru September (Figure 46). Spatially, nitrate is high at several sites throughout the basin especially the Discharge at SLD and New Jerusalem Drain—both of which carry subsurface agricultural drainage (shallow groundwater) and had the majority of concentrations reported above 45-mg/L. The Harding Drain within the Eastside Basin was also somewhat elevated with values ranging from 9.9 mg/L to 44 mg/L. Overall, the Westside Ba-sin had the highest median nitrate concentration (12-mg/L) when compared to the rest of the SJR Basin (Figure 47). Information from the specific sub-basins is listed below. Northeast Basin: The Northeast Basin had very low levels of nutrients and most of the collected sample results were non-detect. The Mokelumne River had only 5 samples that were just slightly above detec-tion levels. The Cosumnes River had slightly higher levels of nitrate, phosphorus and potassium than the Mokelumne River. Pixley Slough nutrient levels, unlike Bear Creek, have lower levels of nutrients than the Cosumnes River. Bear Creek had the highest concentrations of nutrients for the Northeast Basin. Higher concentrations of nutrients mostly occurred during the winter months. Eastside Basin: The Eastside Basin river sites had low concentrations similar to the Northeast Basin river sites. French Camp Slough and Lone Tree Creek had higher fluctuating levels than Bear Creek in the Northeast Basin. Harding Drain had higher fluctuating levels for all nutrient samples collected in the basin. Turner Slough had high levels during January 2001 through April 2001 for TKN, phosphorus, orthophosphate-P and potassium. For the rest of the sampling period the concentrations at Turner Slough were comparable to the river sites within the basin. Southeast Basin: The Southeast Basin had fluctuating levels of nutrients similar to Bear Creek in the Northeast Basin. South Delta Basin: All sites within the South Delta Basin reported low levels of nutrients except for ni-trate levels in the New Jerusalem Drain. The nitrate levels in the New Jerusalem Drain were six times higher than the other South Delta Basin sites as well as the river sites of the Northeast Basin.

Westside Basin: Overall the Westside Basin reported higher nitrate levels than the other Basins (Figure 47). Salado and Orestimba Creeks showed higher concentrations during the winter months and Del Puerto Creek typically showed a spike during the irrigation season. Grassland Basin: The discharge from SLD had the highest concentration of nitrate, but had lower con-centrations of the other nutrients compared to the rest of the Grassland sites. Nitrate concentrations in the SLD were highly elevated in the winter and decreased somewhat but remained elevated above 45-mg/L through the irrigation season. Mud Slough (north) downstream of the SLD discharge tracked the drain’s concentrations and had much higher concentrations of nitrates than Mud Slough upstream. The Main Stem SJR showed increasing nitrate concentrations between Lander and Patterson—the stretch of river receiving inflows from the Grassland (including SLD) and Westside Basins and the Merced River (Figure 48). Nitrates decrease from SJR at Patterson to Airport Way with inflows from the Tuolumne and Stanislaus Rivers. Most other nutrient concentrations decreased in the main stem of the river moving down the system or stayed the same resulting in very low concentrations. The New Jerusalem Drain enters the SJR downstream of Airport Way. Figure 44: San Joaquin River Main Stem Nitrate WY01 – WY04

12.1.10 BIOCHEMICAL OXYGEN DEMAND As with the nutrient samples, Biochemical Oxygen Demand (BOD) samples were collected throughout the basin on a monthly basis through WY02. At the end of fiscal year 02/03, an initial review of the data collected was completed, as well as a review of collaboration efforts with the DO Total Maximum Daily Load (TMDL) effort. A change in the monitoring strategy for the DO TMDL eliminated the need for continued BOD analyses by this effort. Biochemical Oxygen Demand (BOD) is a procedure that measures how fast biological organisms use oxygen in a body of water. Bodies of water with higher concentrations of organic matter have aerobic bacteria that decompose organic matter using the available oxygen within the water body. High nitrates and phosphates also contribute to higher BOD because they contribute to increased plant and algae growth which increase plant loss contributing to higher organic waste. Increased temperatures also contribute to higher algae growth. For this discussion we will be looking only at BOD5 (biochemical oxygen demand 5-day test). Higher fluctuations in BOD5 occurred at most sites during the winter months and corresponded to spikes in flow and TOC. Concentrations of BOD5 also increased and remained elevated during sum-mer months, peaking during September, which again tracked TOC concentrations. Spatially, all of the Eastside river sites had low concentrations of BOD5 which reflect their low concen-trations of TSS and TOC, when compared to the rest of the SJR Basin sites. The rest of the basin sites, except New Jerusalem Drain, had higher levels of TOC and TSS, and BOD5. Figure 49 shows the Northeast basin as a whole had the lowest BOD5 compared to the rest of the Basins. Some distinct findings within each sub-basin are noted below. Northeast Basin: The Northeast Basin Mokelumne River had BOD5 concentrations at or below 1 mg/L. The Cosumnes River had levels similar to the Mokelumne River most of the time except during June 2001, which was just before the river dried and the BOD5 level increased to about 4 mg/L. This in-crease corresponds to the light rain event that occurred just before the river went dry and a similar spike in the TOC concentration. Potential inflow of nutrients and organic matter during the rain event, coupled with the already decreased flows and increased temperatures encourages algae growth, and may have contributed to higher BOD5 levels. Pixley Slough and Bear Creek had higher fluctuations of BOD during the winter months of January and February. Eastside Basin: The Eastside Basin river sites had BOD5 levels mostly under 1 mg/L. There was one very large spike within all the river sites in December 2002, which corresponds to a storm event. The rest of the Eastside Basin sites fluctuate between 2 mg/L to 8 mg/L. The Harding Drain had the highest quartiles compared to the other Eastside Basin sites that had agricultural influences. Southeast and Westside Basins: The BOD5 concentrations in both basins fluctuated like the non-river sites of the Eastside Basin with multiple spikes in the summer and winter. South Delta Basin: The BOD5 concentrations at most of the South Delta Basin sites fluctuated like the non-river sites of the Eastside Basin except for the New Jerusalem Drain. Although the New Jerusalem Drain had high nitrate concentrations, it also had very low TSS and TOC concentrations, and BOD5 levels hovering just above the detection limit of 0.1 mg/L. Grassland Basin: The Grassland Basin fluctuated like the non-river sites of the Eastside Basin as well but fluctuated at slightly lower levels. The Main Stem SJR sites whisker plot (Figure 50) looks very similar to the TOC whisker plot (Figure 38). BOD5 has a very similar trend to TOC with Sack Dam having concentrations below 1 mg/L. The

SJR at Lander had the highest fluctuations of BOD5 when compared to all the other sampling locations along the SJR. The BOD5 concentrations tend to decrease from SJR at Lander to the SJR at Airport Way where BOD5 is mostly under 2 mg/L.

12.1.11 MINERAL ANALYSIS Mineral samples were collected throughout the basin on a monthly basis during WY01 and sporadically during WY02 and WY03. At the end of fiscal year 02/03, an initial review of the data collected was done, as well as a review of collaboration efforts with other in-house programs, which resulted in a re-prioritization of monitoring efforts and the elimination of minerals from monitoring efforts. Within the limited dataset, some general patterns are discernible. In general, the highest mineral con-centrations occur along the western side of the SJR Basin, with elevated sodium concentrations and sulfate the dominant anion draining from the Grassland and Westside Basins and chloride the dominant anion from the Delta Basin. The eastern side of the SJR Basin reported much lower overall mineral concentrations with chloride the dominant anion. Carbonate was typically not detected or detected at very low levels, usually within the Westside Basin. Along the western side of the valley, the SLD influences overall mineral discharges from the Grassland Basin, with elevated concentrations year-round. Concentrations of chloride and sulfate from the drain tend to dominate concentrations in Mud Slough (north) as winter dilution flow decreases. In contrast, during the dry season, sodium levels are elevated in Mud Slough (north) both upstream and down-stream of the SLD discharge. The upstream concentrations are likely due to shallow groundwater dis-charge into the channel. For the remainder of the western side of the valley, mineral concentrations tended to increase during the winter then decrease but become somewhat elevated during the irrigation season. Sulfate and chloride concentrations all remained below the secondary drinking water MCL (250 mg/L), but sodium tended to remain above the irrigation supply guideline of 69-mg/L. The New Jerusalem Drain was the exception for sodium on the western side of the valley with concentrations remaining near 300 mg/L year-round. Along the eastern side of the valley (the Southeast, Eastside, and Northeast Basins), sodium, chloride and sulfate concentrations all remained well below guidelines. Sodium did tend to show low level spik-ing throughout the year. Some sites did show unique characteristics. Within the Westside Basin, Ingram Creek displayed pro-nounced seasonal fluctuation, similar to Tom Payne Slough of the Delta Basin, with marked increases in all minerals during storm events. Mud Slough (north) upstream of the SLD, was lower than the SLD in all mineral concentrations except total alkalinity and bicarbonate. While seasonal fluctuations of mineral concentrations are not distinctly seen within the SJR, the Main Stem sites do reflect the inflows from the various sub-basins. Mud Slough (north)’s influence on Hills Ferry is distinctly seen with all the mineral concentrations at this site consistently higher compared to the rest of the river. Sack Dam has the lowest concentrations within the river, but with the influences from the Southeast Basin, Grassland Basin and Turner Slough, mineral concentrations peak at Hills Ferry. Once the Eastside Basin rivers enter the SJR, mineral concentrations substantially decrease moving downstream to Airport Way, even with elevated concentrations coming in from the Westside Basin. 12.1.12 TRACE ELEMENTS Trace element samples were collected throughout the basin on a monthly basis through WY02. Hard-ness was analyzed simultaneously for each trace element sample in order to allow evaluation against aquatic life criteria. At the end of fiscal year 02/03, an initial review of the data collected and a review of collaboration efforts with other in-house programs were completed. Re-prioritization of monitoring efforts resulted in a removal of trace element collection. Note that during the collection period reporting limits changed for some constituents.

Many of the results for this study were below the analytical reporting level. Some trace elements did appear to show some trends, depending on the location within the SJR valley. In general, the North-east and Eastside Basin river sites have lower concentrations than the other basins within the SJR val-ley. One issue to note with this finding is that the hardness levels in the northeast basin are also lower when compared to the other sub-basins. Hardness concentration is particularly important for aquatic life because hardness tends to buffer toxic impacts, allowing tolerance of higher concentrations of many trace elements. Some distinct findings within each sub-basin are listed below. Northeast Basin: Most of the trace elements sampled in the Northeast Basin had results below the re-porting limit. Copper and zinc were the only two metals that were consistently above minimum report-ing levels for all the sites within the Northeast Basin. Chromium had multiple samples above detection for most sites except the Mokelumne River which only had two samples for total chromium above de-tection levels. Eastside Basin: The Eastside Basin river sites were similar to the Mokelumne River with non-detect values for all metal constituents, except copper and zinc. The Eastside Basin river sites had more non-detect values for zinc than the Mokelumne River. The non-river sites were comparable to the river sites data, except for having higher concentrations of copper, zinc and total chromium. Nickel was also reported at concentrations above minimum reporting levels for the non-river sites during the winter higher flow periods. Southeast Basin: The Southeast Basin sites were similar to the non-river sites of the Eastside Basin. One exception was Deep Slough which had high levels of arsenic and total nickel reported year-round. South Delta Basin: The New Jerusalem Drain had non-detect values for most of the trace elements except for chromium where high concentrations were detected. Tom Payne Slough trace element con-centrations were similar to that of the Deep Slough, having higher levels of arsenic, but with minimal total nickel. Old River and Mountain House Creek both had very low levels of arsenic. Mountain House Creek, similar to Deep Slough, had total nickel concentrations found throughout the sampling period. Westside Basin: The Westside Basin unlike the Northeast Basin had more detected concentrations of total lead and had higher concentrations and major spikes of copper, zinc, and chromium. Hospital Creek had the largest spikes of copper, zinc, nickel and chromium. These very large spikes seemed to occur mostly during the irrigation season. Del Puerto Creek was the only Westside basin site that did not have any samples above the minimum detection level for lead. Grassland Basin: Salt Slough had very similar concentrations of trace elements compared to Deep Slough with just slightly lower levels of arsenic. Mud Slough Upstream was similar to Salt Slough hav-ing detectable arsenic but at slightly lower concentrations. The dominant trace element concentrations at the Discharge from SLD site were chromium and copper. The majority of the concentrations of trace elements that were seen in the Main Stem SJR were the dominant trace elements identified in the sub-basins including; arsenic, chromium, copper, nickel and zinc. With most of these constituents, trace element concentrations went up from Sack Dam to Hills Ferry due to the Grassland influences and from Hills Ferry downstream to Airport Way concentrations decreased due to the Eastside river influences. This trend is similar to the trend seen with minerals.

12.1.13 TOXICITY Funding constraints limited the overall number of full (three species) water column toxicity tests. The three species tested were fathead minnow (Pimephelas promelas, sensitive to elevated nutrients, es-pecially ammonia), Ceriodaphnia dubia (sensitive to organic chemicals such as orthophosphorus-pesticides), and algae (such as Selanastrum capricornutum, sensitive to trace elements). During Water Years 01, 02 and partially in 03 acute toxicity tests were run on fathead minnow and Ceriodaphnia dubia, and while it was encouraging to see limited if any acute effects, there was concern that dilution flows might be masking some effect. Analyzing samples for chronic toxicity was more costly, but con-sidered a more conservative option. With limited funding during WY 04, toxicity samples for chronic fathead minnow and chronic Cerio-daphnia dubia were collected in the Main Stem during the irrigation season only. During WY 05, toxic-ity samples for acute and chronic fathead minnows, acute and chronic Ceriodaphnia dubia, and acute algae were collected once a month at the various sites shown in Table 1. Funding was not available to run toxicity identification evaluations (TIE) on samples identified as a toxic event and therefore results can only be evaluated against data collected during each sampling event. The sporadic sampling did not discern specific trends. Results in Table 6 are discussed by sub-basin below. Northeast Basin: Northeast Basin had recorded toxicity in the Cosumnes River and Bear Creek for the acute fathead minnow test (Table 6). One hundred percent of the four samples collected at Cosumnes River for the acute algae test had a reduction of cell growth. The Mokelumne River only displayed tox-icity for the chronic fathead minnow test. The rest of the samples during the sampling period displayed no toxic event. Eastside Basin: Within the Eastside Basin acute fathead minnow toxic events were only reported for French Camp Slough. Lone Tree Creek had one toxic event for acute Ceriodaphnia dubia. Acute al-gae and chronic fathead minnow test were only conducted at the river sites, except for four acute algae samples collected at Harding drain, and each site had toxic events (for algae reduction and increase in cell growth were found). Over 50 percent of the samples collected at Tuolumne River reported toxic events for the chronic fathead minnow test. Southeast Basin: Bear Creek at Bert Crane Road had three toxic events for the acute fathead minnow test. The remainder of the samples displayed no toxic events. South Delta Basin: The New Jerusalem Drain had one toxic event for the acute fathead minnow test and the acute Ceriodaphnia dubia test. Both of the two samples collected for the acute algae toxicity had a growth statistical difference which could be due to the very high nitrate concentrations within the New Jerusalem Drain. Tom Payne Slough had one toxic event (reduction of cell growth) out of one sample collected for the acute algae test. Mountain House Creek had one toxic event (increase in cell growth) out of two samples collected for the acute algae test. Westside Basin: Toxic events were seen at Orestimba Creek, Grayson Drain and Hospital Creek for the acute Ceriodaphnia dubia test. No other toxic events were observed. Note that only acute fathead minnow and Ceriodaphnia dubia samples were collected and analyzed within the Westside Basin. Grassland Basin: Salt Slough had a total of three acute algae samples collected with two having a re-duction in growth and one being an increase in algae growth. None of the seventeen samples col-lected at Salt Slough for acute fathead minnow or acute Ceriodaphnia dubia had toxic events.

Spatially, not one basin stands out from the rest. As a whole, a majority of the acute algae samples within the SJR Basin had a toxic reduction or growth in algae. Only twelve samples out of 59 collected throughout the basin did not have a statistical difference from the control whether being a reduction or increase in algae growth. The Main Stem SJR sites reflected the same finding of the Basin sites with only eight out of the 31 samples of acute algae not having a statistical reduction or increase in growth when compared to the controls. At least one toxic event was found in each of the Main Stem sites sampled for the chronic fathead minnow and chronic Ceriodaphnia dubia tests.

12.2 Evaluation of Beneficial Uses To evaluate potential impact, indicators were chosen for four broad beneficial uses as shown in Table 3:

1. Drinking water (Specific Conductivity, Total Organic Carbon, Trace Metals, Nutrients); 2. Aquatic life (pH, Temperature, Dissolved Oxygen, Turbidity, Trace Metals, Minerals and Water

Column Toxicity); 3. Irrigation water supply (Specific Conductivity, Minerals); and 4. Recreation (bacteria).

Exceedances/ elevated levels tables were created with the data collected using the applicable water quality goals and objectives as described in section 9.2. Appendix P provides the exceedance/ ele-vated levels tables which compare the total number of samples collected with the total number showing elevated levels for temperature, pH, SC, TOC, DO, turbidity (within the legal boundaries of the Delta), bacteria, nitrate, nitrate-N, ammonia-N, chloride, sulfate, TDS, sodium, total and dissolved arsenic, total and dissolved cadmium, total chromium, total and dissolved copper, total and dissolved lead, total and dissolved nickel, total and dissolved zinc and total mercury. Most of the criteria used to set trace ele-ment limits take into account the hardness of the water at the time of sample collection since increasing hardness will tend to buffer the effect of particular trace elements. The hardness calculations were taken into account in both the summary tables presented in Appendix P and the discussion here. Con-stituents in Appendix P are evaluated against multiple objectives and goals, when applicable, for com-parison of beneficial use impacts. Turbidity outside the Delta is discussed separately below. The Basin Plan Objective for turbidity within the San Joaquin River Basin was designed for point source discharges. When evaluating turbidity basin wide, with weeks between turbidity results and miles be-tween sites, the following evaluations should be looked at objectively and viewed as an overall com-parison of the basin. With this in mind, see Table 7 for the selected upstream sites that were chosen to describe “natural background” for this Basin Plan Objective. Note for Cosumnes River at Twin Cities Road, Bear Creek at Lower Sacramento Road, French Camp Slough at Airport, and Lone Tree Creek at Austin Rd that the sites were compared to the Delta objective because they discharge directly into the Delta. Also, upstream sites are really not applicable to compare with the Main Stem river sites and were not evaluated using the above approach. Turbidity effects along the Main Stem are discussed in section 12.1 of the discussion section. Monthly geometric means were used because of collection time differences. See Table 7 for the number of times the monthly geometric mean of a site is greater than the monthly geometric mean of the selected upstream site using the calculations of the Basin plan objective. The following discussion highlights information from Appendix P and Table 7 to assess beneficial use status in the SJR Basin.

Drinking Water (Specific Conductivity, Total Organic Carbon, Trace Metals, E. coli, Nutrients) Indicators used to evaluate a potential impact to drinking water (sources of municipal and domestic supply) included salt measured as specific conductivity (umhos/cm), total organic carbon (TOC), se-lected trace elements (total arsenic, cadmium, copper, mercury, nickel, lead and zinc), nitrate and E. coli. For all of the indicators except E. coli, there are specific numeric objectives or goals for drinking water that results can be evaluated against (Appendix Q1 and Q2). There are no specific numeric cri-teria for E. coli related to consumption but the presence of E. coli would indicate that the water would need to be treated prior to consumption. For specific conductivity, the California Secondary MCL of 2200 umhos/cm for short term exposure was utilized. Elevated levels are found in the South Delta Basin non-river sites and in Salado Creek within the Westside Basin. The Main Stem sites that displayed elevated levels above this goal were SJR at Lander, SJR at Fremont Ford and SJR at Hills Ferry. These Main Stem sites are located upstream of the first eastside inflow (Merced River) and are therefore dominated by groundwater accretion and in-flows from the Southeast and Grassland Sub-basins. Once the Eastside rivers flow into the SJR, the specific conductivity within the SJR declines until Vernalis. The TOC goal of 3.0 mg/L is based on the Bay Delta Authority’s guideline for water quality in the Sac-ramento-San Joaquin Delta (Cal Fed Bay-Delta Program, 2000). This indicator was chosen to help identify potential sources of TOC to the Delta since all water bodies monitored flow into the San Joa-quin River and ultimately into the Delta. Overall TOC concentrations were reported above 3.0-mg/L throughout the SJR Basin (Figure 51). The Northeast Basin had the lowest concentrations of TOC compared to the rest of the SJR Basins, but still exceeded 3.0-mg/L about half of the time. Storm events and agricultural runoff during the irrigation season correlated well with many of the spikes in concentration, but the goal was surpassed in the majority of the sites at other times of the year as well and at sites that were not identified as receiving agricultural return flows. Roughly 10-percent of the 526-nitrate samples collected exceeded the nitrate California Primary MCL (45 mg/L). All of the 10 samples collected at New Jerusalem Drain (representing shallow ground water in the Westside Basin) were above this objective. The Grasslands Basin also had elevated levels of nitrate at all sites except Mud Slough upstream of SLD. Two sites (Discharge at SLD and Mud Slough (downstream) @ SLD—both within the Grassland Basin) had samples that exceeded the nitrate-N Cali-fornia Primary MCL (10 mg/L). For total arsenic two goals were evaluated for drinking water: 1) the Basin Plan Objective for the Cali-fornia Primary MCL of 50 µg/L and 2) the USEPA Primary MCL of 10 µg/L. No samples exceeded the Basin Plan objective during the 5 year sampling period. Thirteen samples exceeded the USEPA pri-mary MCL. The three sites that had elevated levels above this goal were SJR at Lander, Deep Slough and the Grayson Drain. The total cadmium Basin Plan Objective for the California Primary MCL of 5 µg/L, total copper Basin Plan Objective for the California Primary MCL of 1000 µg/L, and the total zinc Basin Plan Objective for the California Primary MCL of 5000 µg/L were never exceeded during the 5 year study. The total chromium Basin Plan Objective for the California Primary MCL of 50 µg/L, total lead Basin Plan Objective for the California Primary MCL of 15 µg/L, and the total nickel Basin Plan Objective for

86

California Primary MCL of 100 µg/L were all exceeded by three sites in the Westside Basin. Hospital Creek, Ingram Creek and Grayson Drain exceeded these goals during the irrigation season. The total mercury Basin Plan Objective for the California Primary MCL of 2 µg/L was never exceeded during the 5 year sampling period. Total mercury was found elevated above the California Toxics Rule (USEPA) for sources of drinking water, 0.05 µg/L, once in Hospital Creek (0.2 µg/L). Table 8 is a quick summary to show whether the river or any of the basins have potential beneficial use impacts based on the indicators evaluated.

Aquatic Life (pH, Temperature, Dissolved Oxygen, Turbidity, Trace Metals, Minerals and Water Column Toxicity) The Basin Plan objective for pH for freshwater with COLD or WARM beneficial uses is a range between 6.5 to 8.5 units. Each of the Basins exceeded this objective multiple times, but no site exceeded this objective more than 18 percent of the time. The Main Stem and the Grasslands exceeded this objec-tive during the summer irrigation season. The other basins exceeded this objective randomly with dras-tic fluctuations. The Bay-Delta Authority target for a temperature of 20ºC from April 1 – June 30 and from September 1 – November 30 applies to the San Joaquin River at Vernalis. Samples collected at Vernalis had tem-peratures recorded above this target 41% of the time during the 5-year study. Every site within the SJR Basin reported temperatures above this target at least once during the sampling period with the highest percentages seen within the Southeast and Grassland Basins. The dissolved oxygen Basin Plan objective of 7.0-mg/L (described in Appendix Q1 as outside the Delta for cold/spawning beneficial use) was used for all non-Delta sites. Results were found below the above objective at least once for every site except for the Cosumnes and Stanislaus Rivers. The basin with the highest percentage of results below the objective was the Northeast Basin in the non-river sites and the lowest percentages were found in the Westside Basin. Sites within the legal boundaries of the Delta were evaluated against the Basin Plan objective of 5.0 mg/L for dissolved oxygen. All Delta sites were below this objective at least once except New Jerusalem Drain. Tom Payne Slough had the high-est percentage of results below this objective with 19 out of 47 samples. Sites within the legal boundaries of the Delta were evaluated against the Basin Plan objective of 150 NTU for turbidity. This objective was only exceeded once at Mountain House Creek during a non-storm event. New Jerusalem Drain and Mountain House Creek both exceeded the objective during the De-cember 2002 storm event, however this objective doesn’t apply for storm events. For non-Delta sites the Basin Plan objective was designed for specific discharges. As described in the turbidity results sec-tion of this report, Table 7 attempts to use the Basin Plan objective to have an overall assessment of the SJR Basin turbidity concentrations. The Westside Basin had greater turbidity 71 percent of the time compared to the selected upstream sites. Higher turbidity levels were typically associated with major storm events and irrigation seasons. The USEPA California Toxics Rule for total and dissolved cadmium, total and dissolved nickel, dis-solved arsenic, dissolved lead, and dissolved zinc was never surpassed during the sampling period. No samples were elevated above the USEPA National Ambient Water Quality Criteria for 1 hour aver-age of 1.4 µg/L for total mercury during the sampling period. The USEPA California Toxics Rule for total and dissolved copper was exceeded in multiple samples, primarily in the non-river sites of the Northeast and Eastside Basin, particularly in French Camp Slough, Lone Tree Creek, and Pixley Slough. In addition the Westside and Southeast Basin had a few elevated samples for total copper as well. The USEPA California Toxics Rule for total lead was exceeded once in the Mokelumne River. Pixley Slough reported one sample above the USEPA California Toxics Rule for total zinc. Even though the concentrations of the metals were lower in the Northeast and Eastside Basins when compared to the Westside Basin, the hardness levels were also comparatively low which resulted in lower concentration thresholds that could impact aquatic life.

No sample was reported above the chloride USEPA National Ambient Water Quality Criteria for 1-hour average of 860 mg/L during the study. Various levels of water column toxicity were reported on multiple occasions (Table 6). A higher per-centage of chronic toxicity was reported as compared to acute toxicity. Acute algae toxicity samples were collected less frequently than other toxicity samples, but had the highest percentage (50 percent) of toxic findings (samples having a reduction or increase in growth at all sites except for Fremont Ford). In summary there were multiple concerns throughout the basin for aquatic life. Drastic fluctuations of pH occur at multiple locations, but for the majority of the time most sites are within range of the Basin Plan objective. Elevated temperatures during the spring and fall may impact fish migration. Low DO levels were seen in multiple sites, most consistently in non-river sites, but no overt impact (e.g. fish kills) was ever noted. Trace element results exceeding hardness adjusted criteria were mostly reported in the Northeast and Eastside basins—as were the lowest hardness concentrations. Total copper was the primary trace element of concern having higher percentages of elevated levels in French Camp Slough, Lone Tree Creek, and Pixley Slough. Turbidity concentrations can become highly elevated during storm events and the irrigation season but become difficult to interpret with the fluctuation of background concentrations. Irrigation Water Supply (Specific Conductivity, Minerals) For specific conductivity the Basin Plan has an objective of 700 umhos/cm April through August and 1000 umhos/cm September through March for SJR at Airport Way (also known as Vernalis). This ob-jective only applies to a maximum thirty day running average. Although approximately 21 percent of individual samples collected at Vernalis had concentrations above the noted objective during the sam-pling period, exceedances can not be determined using the limited grab samples. Multiple samples at concentrations above the Water Quality Goal for Agriculture of 700 umhos/cm (Marshack, 2003) were found in all basins except the Northeast Basin. The Eastside Basin had the lowest percentage of elevated samples (39 out of 409—9.5%) and the Grasslands (1047 out of 1049--~100%), Westside (330 out of 516—64%) and the South Delta Basin (163 out of 188—87%) had the highest percentages of elevated samples. Multiple samples collected along the SJR also had concen-trations reported above the Water Quality Goal for Agriculture. The elevated concentrations were con-sistently clustered between Lander Avenue (primarily ground water accretions) and Maze Blvd., a stretch of river receiving inflows from the Grassland, Eastside and Westside Basins. Chloride and sodium concentrations that were above water quality goals of 106 mg/L and 69-mg/L, re-spectively, tracked elevated levels of specific conductance. Concentrations above the total dissolved solids Water Quality for Agriculture goal of 450 mg/L occurred mostly in the Grasslands and Westside Basin. The Northeast Basin was never above this goal and most of the elevated concentrations reported in the Eastside Basin were found in the Harding Drain. In summary, salt concentrations throughout the SJR Basin appear to be elevated above optimal con-centrations for irrigation water supply, except within the Northeast and Eastside Basins. Salt is a well documented issue within the Grasslands and Westside Basins, with the natural background of the area being highly saline and high salinity water being pumped from the Delta to meet agricultural needs. Huge continuous efforts to control salt have been implemented in the past and continue to this day.

See the future actives section 14.0 of this report for more information on the current efforts being made to address salt in the SJR valley. Recreation (Bacteria) All the sites monitored during this study are either specifically designated or tributary to a water body designated for full contact recreation (e.g. swimming), except for the San Luis Drain and New Jerusa-lem Drain. As a conservative approach, the USEPA Guideline for full contact of 235 MPN/100ml E. coli was used to evaluate the entire SJR basin. Many of sites may not support full recreational contact due to physical attribute (e.g. ankle deep water), however, the use of a single guideline provided consis-tency for the review. The highest percentages of E. coli concentrations exceeding 235 MPN/100ml were found in the West-side Basin and the non-river sites of the Eastside Basin (Figure 52). E. coli spikes were seen during high and low flow events meaning E. coli spikes are randomly present during both winter storm events when it would be unlikely to find people swimming and during the warmer summer season when most recreational contact would occur.

13.0 SUMMARY/CONCLUSION In general the SJR receives drainage from a variety of diverse basins. For example, the Grassland Ba-sin is a highly managed system that is dominated by agricultural influences (both traditional cropland and managed wetlands) and receives water from the Sacramento-San Joaquin Delta to support the land use. The Northeast Basin contains the Cosumnes watershed which drains snowmelt from the Si-erras and is the last major water body within the Central Valley that does not have flow regulated by a major reservoir. Most of the drainage basin sites are within the valley floor which is dominated by agri-cultural use and urban development. Even though the land uses are similar for most of the drainage basin sites, the source water from their upper watersheds are completely different across the basins and create a truly unique and complex system. The spatial trend for most constituents (SC, TSS, turbidity, metals, and minerals) within the SJR is that concentrations seem to increase from Sack Dam to Hills Ferry, as a result of the Grassland influences, and decrease from Hills Ferry down to Vernalis due to the Eastside Basin river sites contribution of high flow Sierra snow melt and reservoir storage flows. Other constituents displayed strong seasonal trends that were consistent throughout the whole SJR valley floor. For instance, temperature increased at all sites during the warm summer months. Dis-solved oxygen concentrations decreased at all sites during the warmer summer months, which may be offset by algal blooms as well as temperature, with a decrease in dramatic fluctuation within SJR sites during the wet WY of 2005. Specific conductivity, TOC, turbidity, and TSS were influenced by storm events, specifically for SC the first storm runoff, and the irrigation season. Findings by individual Basins included: Northeast Basin:

Northeast basin had the lowest levels for most constituents compared to the rest of the SJR ba-sin. All of the four samples collected for acute algae at Cosumnes River had a reduction of cell growth. This reduction could be due to the minimal nutrients and minerals found in the Cosum-nes River watershed, but a toxicity identification evaluation was not conducted.

Eastside Basin:

The Eastside Basin river sites (Merced, Tuolumne and Stanislaus) typically followed the North-east basin with low levels for most constituents compared to the rest of the basins. In contrast, the Harding Drain reported the elevated levels of SC, E. coli, nutrients, BOD and min-erals. Harding Drain also had dramatic fluctuations of DO.

Southeast Basin:

Deep Slough had high year round levels of arsenic and total nickel which was unique for the en-tire SJR Basin and had the majority of detected samples during high flow events.

Page 94: San Joaquin River Basin: Main Stem ... - waterboards.ca.gov · San Joaquin River Basin: ... Victoria Bowles, Environmental Scientist Chad Dibble, ... 1.0 EXECUTIVE SUMMARY

94

South Delta Basin:

New Jerusalem Tile Drain, which represents shallow ground water within the South Delta Basin, had higher temperature, SC, nitrate levels, and minerals compared to the rest of the South Delta Basin. The New Jerusalem Drain, even with its high nitrate concentrations, had very low TSS and TOC concentrations with the BOD typically just above the detection limit of 0.1 mg/L--unlike the rest of the South Delta Basin. The New Jerusalem Drain had non-detect values for most of the metals except high concentrations of chromium.

Tom Payne Slough had a consistent seasonal fluctuation of minerals. High concentrations of minerals are seen during the winter months with a drastic drop in mineral concentrations during the summer months.

Westside Basin:

The Westside Basin sites on average had greater turbidity and TSS than the remainder of the SJR Basin sites with concentrations fluctuating greatly during the irrigation season and storm events. The Westside Basin also had relatively higher concentrations of nutrients and minerals than other basin sites. The Westside Basin had a high volume of detected values for total lead and had overall higher concentrations and major spikes of copper, zinc, and chromium.

Grassland Basin:

The Grassland Basin was sampled more frequently for every site other than those on the main stem of the SJR due to the compliance monitoring program for the Grassland Bypass Project (se-lenium control program). For all sites within the Grassland Basin, other than for Salt Slough, there is a clear seasonal fluctuation for pH. The pH tends to peak in July and drop to its lowest around January mirroring the temperature results. The Grassland Basin has high levels of SC, TSS, and minerals compared to the eastern basins. Salt Slough, having a total of three algal toxicity samples collected, had two toxic events for the increase in growth for acute algae and one toxic event for a reduction in algal growth. Of the se-venteen samples within Salt Slough collected for acute fathead minnow and acute Ceriodaphnia dubia, no toxic events were found.

When evaluated against the water quality objectives and goals found in Appendix Q1 and Q2 there are multiple areas of concern within the SJR Basin. Drinking Water/Municipal Supply: High TOC levels throughout the SJR valley are elevated above guidelines for the delta intended to pro-tect drinking water.

Aquatic life: Elevated temperatures throughout the basin were a concern during the spring and fall. Total copper had high occurrences in French Camp Slough, Lone Tree Creek, and Pixley Slough. Turbidity was a concern within the Westside Basin, but a more applicable Basin Plan objective is needed to determine potential for impairment. Irrigation Water Supply: When compared against the Water Quality Goal for Agriculture of 700 umhos/cm, large areas of the basin appear to be elevated above optimal irrigation water quality guidelines for specific conductance. Salt is an overwhelming ongoing concern for most of the SJR Basin particularly the Grasslands and Westside basin. Recreation: E. coli had occasional spikes during the summer months when most of the waterways have a potential for recreational use. A majority of the sites with high percentages of samples exceeding the conserva-tive level percentages may need further evaluation to determine actual level of potential recreational use. 14.0 FUTURE ACTIVITIES While information collected during this study was utilized to help fine tune the monitoring programs for the Northeast, Eastside and Westside Sub-basins during the rotational portion of the overall effort, after WY 2005 the SJR SWAMP effort was not able to continue the Drainage Basin or Intensive Rotational Basin sites due to funding reductions. Since 2005, the SJR SWAMP sampling has been limited to maintaining the water quality monitoring for the multi-agency Grassland Bypass Project (GBP), with ad-dition of E. coli analyses twice a month at the GBP sites. Since 2003, expanded monitoring of agricultural drainage inflows to the SJR have been conducted by various Agricultural Coalition Groups as part of the Irrigated Lands Regulatory Program (ILRP). SWAMP is providing resources to ensure ILRP water quality information is captured in the statewide SWAMP master database. To address the salt issue within the SJR Basin the Central Valley Water Board formed the Central Val-ley Salinity Alternatives for Long-Term Sustainability (CV-SALTS). This program is an effort to address the salinity problems within the Central Valley and will adopt long-term solutions to improve water qual-ity and economic sustainability. The following website has up-to-date information about CV-SALTS: http://www.swrcb.ca.gov/centralvalley/water_issues/salinity/index.shtml . The Central Valley Water Board SWAMP effort has refocused limited resources on better identifying current monitoring efforts conducted by both internal programs (GBP, ILRP, NPDES receiving water requirements, TMDL, and others) and major external efforts (Department of Water Resources, US Bu-reau of Reclamation, US Geological Survey, University of California and watershed groups) through the development of a web-based surface water monitoring directory. The directory builds off of a pilot pro-ject with the San Francisco Estuary Institute (SFEI) begun by the US EPA within the San Joaquin River Basin, and has been expanded by the Central Valley Water Board SWAMP to include the entire Central

Valley (Sacramento, San Joaquin, and Tulare Basins and Delta). The web-based monitoring directory is designed to only display active monitoring efforts and to identify what is being monitored where, how frequently, for how long, and by which agency. While actual data is not captured, the directory will pro-vide links to any web based database and contact information for the monitoring program manager. Initial feeding of the directory has focused on multi-agency efforts within the Sacramento-San Joaquin Delta to help identify available water quality information in order to facilitate a more thorough evaluation of water quality. In addition, the directory has been beta-tested by loading information on the internal GBP, ILRP, NPDES, statewide SWAMP, and DWR Northern District efforts for the entire Central Val-ley. The directory can currently be viewed at the following website http://www.centralvalleymonitoring.org/. It is anticipated that beta testing will be complete and the di-rectory will be available for data entry from interested parties during late spring 2009. Central Valley SWAMP is also currently:

• Providing resources (staff and contract dollars) to facilitate development of a Regional Monitor-ing Program for the Sacramento-San Joaquin Delta.

• Supporting the Department of Water Resources staff to continue long-term trend monitoring at

41-sites in the northern Sacramento River Basin in exchange for the addition of selected con-stituents of concern identified through Central Valley Regional Board efforts (TOC, nutrients, and toxicity) and realignment of 11-sites to correspond with sites utilized by the statewide SWAMP sediment toxicity study.

• Developing a region-wide, long-term trend monitoring framework based on the 30-sites within

the Central Valley that are part of the state-wide SWAMP contaminant trend monitoring effort

• Development of the Central Valley Regional Board SWAMP website that documents monitoring activities supported by SWAMP and provides links to final reports and selected water quality data (http://www.waterboards.ca.gov/centralvalley/water_issues/water_quality_studies/surface_water_ambient_monitoring/index.shtml)

Efforts related specifically to the elevated E. coli concentrations found within the SJR Basin as well as in other areas of the Central Valley as part of ILRP monitoring, include:

o A survey of E. coli concentrations in local swimming holes before during and after a holiday weekend (coordinated with Central Valley watershed groups during both 2007 and 2008)

o A pilot bacteria source identification project with the University of California, Davis, in selected streams with a history of elevated E. coli concentrations

o Continued, seasonal E. coli monitoring at 30-major integrator sites throughout the Central Val-ley.

Recommendations for future monitoring for each sub-basin and river site include those parameters identified in Table 8. Data has been posted annually on our website since 2003 and utilized in combi-nation with other available data for assessment in the Clean Water Act Sections 305(b) and 303(d) In-tegrated Report for the Central Valley Region (CVRWQCB, 2009 Draft).

* Significantly reduced from the lab control.** Significantly greater than the lab control.^ Fish were from a "forced hatch," duplicate failed QA.1 Duplicate sample for the set was low - 77% recovery.

3 Samples qualified, but duplicate sample recovery for the set was high - 126% (53.8%/42.5%)NA = Data not applicableINA = Site was inaccessibleDRY = Site had no flow

2 Testing for the Fathead minnow was initiated when samples were approx. 48h old due to untimely shipping of fish by fish supplier.

Note: This site was changed from the Thornton Rd. site (May of 2002) due to the influx of tidal waters from the Delta. The new (Lower Sacramento Rd.) site is upstream of the tidal influence.

The slough was isolated off from the San Joaquin River with the construction of the Eastside Bypass. With the construction of Friant Dam, the Slough rarely conveys natural flood flows. There are discharges of tailwater into various reaches of the Slough, but these are not sufficient to sustain a continuous flow. The Slough is dominated by these flows as there is no other flow in the Slough. Some of these tailwater flows are diverted for agricultural use.

Natural runoff occurs for 2-3 months of the year upstream of power lines which transverse the creek approximately 1.5 miles upstream of Interstate 5. Downstream of the power line, the Creek channel is dominated by agricultural return flows from March to November. Downstream of the Delta Mendota Canal, the flood channel has been extensively reworked; now it can be considered a constructed channel carrying only agricultural return flows that is then piped underground from Highway 33 until it discharges into the San Joaquin River along Olive Avenue.

N3: 541STC516 – Del Puerto Creek at Vineyard Avenue

MONITORING SITE INFORMATION Site Description, Location and Access: Del Puerto Creek at the intersection of Vineyard Road and Loquat. The creek is sampled at the bridge. Latitude/Longitude: Lat. N 37° 31’ 17.3” Long. W 121° 08’ 55.3” County: Stanislaus WATER SOURCE Type and source of water being monitored (description): The majority of the water in Del Puerto Creek is tail water from irrigated fields in the adjacent areas. Also in the creek is operational spill water from both West Stanislaus Irrigation District and Patterson Water District. Little if any tile drainage enters the creek. It would be expected that seepage into the creek from high groundwater would also be present but little is found. Comments on factors affecting water quality and quantity at the site: The quality of the creek will be related to the operational spill water quality and the quality of the tail water leaving individual fields.

O2: 544SJC505 – Tom Paine Slough at Paradise Road

MONITORING SITE INFORMATION Site Description, Location and Access: Exit North onto Macarthur Boulevard off of Interstate 205. Make a right hand turn onto Arbor Road. Follow Arbor Road until it dead ends into Paradise Road. Make a left hand turn onto Paradise Road. Follow Tom Payne Slough along the right side of Paradise Road until you come to the bridge. Access is via the Northeast corner of the bridge. Latitude/Longitude: Lat. N 37° 46’ 27.1” Long. W 121° 22’ 55.8” County: San Joaquin WATER SOURCE Tom Payne Slough is a natural flood channel of the San Joaquin River. River and agricultural development has cut off the Slough from the San Joaquin River. Flow in the Slough is now from the Delta and return flows entering the Slough. The Slough, from its origin near the San Joaquin River to the tide gates at Sugar Cut, is dominated by agricultural activities and return flows. The portion downstream of the tide gates is a natural channel, but flow and quality are affected by NPDES discharges near Sugar Cut. These discharges also affect the quality in Tom Payne Slough during high tide periods as water flows into the Slough.
