FISH ENTRAINMENT AND TURBINE MORTALITY STUDY
HOLT PROJECT
FINAL REPORT
ALABAMA POWER COMPANY
EXECUTIVE SUMMARY
Alabama Power Company (Alabama Power) is currently in the process of relicensing the
existing 46.9 megawatt (MW) Holt Hydroelectric Project (License No. 2203). The Holt
Hydroelectric Project (“Holt” or “Project”) is located on the Black Warrior River at the U. S.
Army Corps of Engineers (USACE) Holt Lock and Dam in Tuscaloosa County, Alabama. The
Project stakeholders agreed to address fish entrainment and turbine mortality through the use of a
“paper based” study. Kleinschmidt used a database of nine studies to estimate potential
entrainment at the Project. This analysis estimated that 687,851 fish are potentially entrained by
the Project annually. Kleinschmidt also used the database as well as site-specific information to
determine the species composition and length frequency of the fish entrainment estimate. The
major families of fish represented in this estimate are Clupeidae, Centrarchidae-panfish, and
Ictaluridae. Most of the fish in this estimate were six inches or smaller. Turbine mortality
estimates for Kaplan/propeller type turbines were based on 58 studies which ranged from 3.9 to
37% and were species specific. When these percentages were applied to the entrainment
estimate, it was predicted that 66,768 fish are lost by turbine operation at the Project in an
average water year.

ALABAMA POWER COMPANY
1.0 INTRODUCTION
Alabama Power Company (Alabama Power) is currently in the process of relicensing the
existing 46.9 megawatt (MW) Holt Hydroelectric Project (License No. 2203). The Holt
Hydroelectric Project (“Holt” or “Project”) is located on the Black Warrior River at the U. S.
Army Corps of Engineers (USACE) Holt Lock and Dam in Tuscaloosa County, Alabama. The
Holt powerhouse is connected to Holt Lock and Dam, and the lands and shoreline within the
Project Boundary are owned by the USACE, state, and private entities. Alabama Power has
easements on the land from the USACE and private interests. Holt Lock and Dam and Holt Lake
(hereinafter referred to as “Lake”, “reservoir” or “pool”) are owned and operated by the USACE
and are not licensed by FERC. The USACE controls the river flow at the Lock and Dam and the
Project utilizes the surplus water for generation of electricity.
Alabama Power’s existing FERC license for the Project expires on August 31, 2015; therefore
Alabama Power’s relicense application for a new operating license must be filed with the FERC
on or before August 31, 2013. Alabama Power is developing a new license application using the
Traditional Licensing Process (TLP) (18 C.F.R. § 5.6 and 16.8). Relicensing stakeholders
identified fish entrainment and turbine mortality as an issue to address during relicensing of the
Holt Project. Alabama Power proposed to perform a desktop entrainment and turbine mortality
analysis to address stakeholder concerns (see Study Plan, Appendix A).
2
The goals of this “desktop” Entrainment and Turbine Mortality Study were to:
a. Estimate the number, species composition, and length frequency distribution of fish potentially entrained at the Project annually; and
b. Estimate the number, species composition, and length frequency of fish potentially lost annually due to turbine mortality.
1.1 PROJECT DESCRIPTION
The Holt Project was placed into service in 1968 by Alabama Power. The powerhouse contains a
46,944 kilowatt (kW) generator connected to a fixed-blade propeller turbine rated at 61,333
horsepower (hp) with a net head of 60 feet and a 115 kilovolt (kV) substation. The turbine has a
minimum hydraulic capacity of 1,000 cubic foot per second (cfs), and maximum hydraulic
capacity of 11,200 cfs. The runner speed is 100 revolutions per minute (rpm) and the runner
diameter is 239.5 inches.
The Project has steel trashrack panels that cover the intake area that feeds water to the turbine.
The trashrack bar rack spacing is 6 inches wide. After flowing through the turbine, the water
releases directly back into the Black Warrior River.
The facility has 14 individually operated Tainter gates, which are used for pool level
management to support navigation and flood control. The maximum reservoir level for the
spillway design flood as determined by the USACE is El. 206.4', which is 0.6 feet below the top
of the embankment dam, gravity section, and intake.
The navigation lock was placed in operation in May 1966 (USACE, 2009a). The lock chamber
dimensions are 110 feet wide and 600 feet long (USACE, 2009b). The lock allows for water
vessels to pass both upstream and downstream at the dam. An average of three to five vessels
pass through the lock daily.

2.0 METHODS
2.1 ENTRAINMENT
Fish entrainment is the passage of fish through the trash rack, penstock, and turbines into the
tailrace of a development. The goal of this desktop study was to characterize and provide an
order-of-magnitude estimate of potential fish entrainment using existing literature and site
specific information. The primary steps in this analysis included:
a. Define the entrainment database that can be applied to the Holt Project; b. Use the entrainment database to develop potential fish entrainment rates, family, and size
composition; c. Determine the average monthly turbine flows for the Project; and d. Estimate the number, family, and size composition of fish potentially entrained through
the Holt Project.
These steps are described in the following sections. 2.1.1 DEFINE THE ENTRAINMENT DATABASE
Over 70 site-specific studies of resident fish entrainment and mortality at hydroelectric sites in
the United States have been performed and reported on to date. These studies provide order-of-
magnitude estimates of annual fish entrainment (FERC, 1995). Table B-1 in Appendix B shows
information from 77 of these studies. Descriptive information gathered from each entrainment
study includes:
a. Project name and FERC project number; b. Location: state and river; c. Project size: discharge capacity and power production; d. Physical project characteristics: trash rack spacing, intake velocity, etc.; e. Project operation: e.g., peaking run-of-river, etc.; f. Biological factors: fishery type; and g. Impoundment characteristics: impoundment size, flow regime.
Using these criteria, the list of entrainment studies was reduced to nine sites. The entrainment
rate information from these nine studies is presented in Table 1 (Entrainment Rate Information
from the 9-Study Database) and Table 3 (Family Group Entrainment Estimates).
4
Freshwater Drum
Entrainment data from two studies where freshwater drum entrainment was experienced were
used to estimate potential freshwater drum entrainment at the Project. A summary of the two
studies and a table depicting characteristics of the original nine study sites, and two additional
freshwater drum study sites, is provided in Appendix C (Table C-1).
2.1.2 FISH ENTRAINMENT RATES
The monthly entrainment rate information from the selected entrainment studies was
consolidated to determine potential fish entrainment rates. All entrainment rates were converted
to fish per million cubic feet (mcf) of water passed through the Project turbines (Study Plan,
Appendix A). Because of gaps in monthly data, monthly rates were averaged to develop seasonal
entrainment rates (Table 1, Entrainment Rate Information from the 9-Study Database) for the
Holt Project.
Seasons were defined as follows:
Winter: December, January, February
Spring: March, April, May
Summer: June, July, August
Fall: September, October, November
2.1.3 SPECIES AND SIZE COMPOSITION
Chris Greene, Alabama Department of Conservation and Natural Resources (ADCNR), provided
a list of species likely to occur in the vicinity of the Project (personal communication, February
28, 2011) (Appendix D). The individual species were grouped into families (Table 2, Species
Likely to Occur in the Vicinity of Holt Lock and Dam Grouped by Families) to compare with the
families in the entrainment study database. Some families likely to occur in the Project Vicinity
were not included in the entrainment database. These species are more likely to prefer open
water habitat (Belonidae, specifically Atlantic needlefish), are not currently present
(Polyodontidae, specifically paddlefish), or are found in tributaries (Fundulidae,
Petromyzontidae, and Elassomatidae). Information was added to incorporate the family
Sciaenidae (freshwater drum), see Section 2.1.1.
5
The species composition data from each accepted entrainment study was analyzed to determine
the general species and sizes of fish typically entrained at other hydroelectric projects in the
study database. This information was grouped to yield estimates of family group (Table 3,
Family Group Entrainment Estimates) and size composition (Table 4, Annual Size Composition
of Fish Family/Genus Groups in the Entrainment Database) for potentially entrained fish.
2.1.4 TURBINE FLOWS
Average monthly turbine flows in day-second-feet (the flow rate measured in cfs averaged out
over one day) were provided by Alabama Power for the period 2000 through 2010 (Alabama
Power, 2011). In addition, as part of the Pre-Application Document (PAD) annual and monthly
flow duration curves for the Project were developed using inflow values into Holt Lock and Dam
which are calculated based on basin inflows and releases from the dam (see Appendix E). The
average monthly turbine flows were converted to total monthly flows in mcf (Table 5, Total
Monthly Flows Through the Holt Project). A day-second-foot is the volume of water
accumulated in one day by a flow of one cubic foot per second. One day-second-foot is
equivalent to approximately 1.9835 acre-feet (acre-ft). One acre-ft is equivalent to 43,560 cubic
feet. The average flows were multiplied by days in the month to calculate total monthly flows.
This flow data was used in combination with entrainment rate data from the nine study database
to estimate the number of fish potentially entrained at the Project (see Section 2.1.5).
2.1.5 CALCULATION OF ENTRAINMENT ESTIMATES
The calculation of entrainment estimates for the Project follow a stepwise process, utilizing the
inputs described in the previous sections. These steps are described below.
Step 1 – Total Number of Fish Entrained by Month and Season
The total number of fish entrained is based on two parameters: seasonal fish entrainment rate
(fish per mcf of water) and Project operation (mcf of water passed through the turbines). To
calculate the total number of fish entrained by month, the appropriate seasonal entrainment rate
was multiplied by the corresponding monthly turbine flow (see example below). Seasonal totals
6
were produced by simply adding the total number of fish entrained for each month within a
season.
Example: 5.0 fish/mcf of water * 1,000 mcf = 5,000 fish
Step 2 – Number of Entrained Fish Within Each Family Group by Season
The percentages for each family group are based on data from the entrainment study database
(see Section 2.1.3). The composition of entrained fish is represented as a percentage of the total
number of fish entrained for each season. To calculate the number of entrained fish within each
family group by season, the total number of entrained fish by season (from Step 1) was
multiplied by the family group seasonal composition percentages.
Example: Total number of fish entrained in Spring = 100,000
Spring composition percentage of Clupeidae = 35%
100,000 * 0.35 = 35,000 Clupeidae entrained in Spring
Step 3 – Number of Entrained Fish Within Each 25mm (1-inch) Length-Group for Each Family
Group
The size composition breakdown for each family group is based on data from the entrainment
study database. The size composition of each family group of entrained fish is represented as a
percentage for each season (see Section 2.1.3). To calculate the number of entrained fish within
each 25mm length-group for each family group, the total number of entrained fish estimated for
each family group was multiplied by the appropriate seasonal size composition percentage.
2.2 TURBINE MORTALITY
As fish are entrained through hydroelectric turbines, some percentages of those fish are killed
due to turbine mortality (i.e., blade strikes, shear forces, pressure changes, etc.). This assessment
included the following steps, as outlined in the Study Plan (Appendix A):
a. Define a mortality database; b. Develop mortality rates for each family group of fish; and c. Apply mortality rates to the entrainment estimate.
7
2.2.1 TURBINE MORTALITY DATABASE
Turbine passage survival studies have been performed at numerous hydroelectric projects
throughout the country over the past 15 or more years. Characteristics of these identified projects
were compared to the characteristics of the Holt Project and appropriate studies were selected for
the transfer of turbine mortality data.
Alabama Power reviewed other project mortality studies and narrowed the list down to the most
applicable studies for use in the Holt turbine mortality database (Study Plan, Appendix A).
Several criteria were applied during this process:
a. Turbine type b. Species of fish tested c. Detail of study information available or quality of the study
When these criteria were applied, 58 turbine mortality studies (for 13 projects) remained in the
database. Pertinent data from these studies is presented in tabular form in Appendix B (Table B-
2).
2.2.2 TURBINE MORTALITY RATE
Information from each of the species/family groups tested in turbine mortality studies was
compiled and presented in Table 6 (Summary of Mortality Rates by Family/Genus Group for
Kaplan/Propeller-Type Turbine Studies). Within each species/family group, mortality rates for
similarly sized fish were averaged to produce a composite mortality rate. In cases where turbine
mortality test data was not available for certain species/family groups, mortality rates for fish
species with similar body types and size ranges were used.
2.2.3 CALCULATION OF THE TURBINE MORTALITY ESTIMATE
Estimates of turbine mortality at the Project were calculated by applying the mortality rates from
the study database to the entrainment estimates.

3.0 RESULTS
3.1 ENTRAINMENT
The mean seasonal entrainment rates used to estimate potential fish entrainment at the Project are
presented in Table 1 (Entrainment Rate Information from the 9-Study Database). The estimated
number of fish potentially entrained for each month was calculated by multiplying the ten-year
average monthly turbine flow for the Project (Table 7, Total Number of Fish Entrained by Month
and by Season) by the appropriate mean seasonal entrainment rate developed from the
entrainment study database.
3.1.1 ESTIMATED TOTAL NUMBER OF FISH ENTRAINED BY MONTH AND SEASON
The estimated number of fish potentially entrained for each month and season at the Project is
presented in Table 7 (Total Number of Fish Entrained by Month and by Season). When all
monthly entrainment estimates were calculated and summed, the estimated annual fish
entrainment was 687,851.
3.1.2 NUMBER OF FISH ENTRAINED WITHIN EACH FAMILY GROUP BY SEASON
The estimated number of fish potentially entrained within each family group by season is
presented in Table 8 (Estimated Number of Fish Potentially Entrained Within Each Family
Group by Season). Three groups that accounted for a majority of the estimated entrainment were
the Clupeidae (44%), Centrarchidae-panfish (20%), and Ictaluridae (17%).
3.1.3 NUMBER OF ENTRAINED FISH WITHIN EACH 25MM (1-INCH) LENGTH-GROUP FOR
EACH FAMILY GROUP
The estimated number of potentially entrained fish within each 25mm (1inch) length-group for
each family group annually and for each season is presented in Table 9 (Annual Size
Composition of Fish Family/Genus Groups in the Entrainment Database).
3.2 TURBINE MORTALITY
9
As noted in Section 2.2.2, mortality test data was unavailable for certain family groups estimated
to be entrained at the Project. As such, data from studies on similar fish species were used as a
substitute. Turbine mortality rates for each family group and length-group are presented in Table
6 (Summary of Mortality Rates by Family/Genus Group for Kaplan/Propeller-Type Turbine
Studies), including an indication of which groups lacked study data and which groups were used
as substitutes.
Table 6 (Summary of Mortality Rates by Family/Genus Group for Kaplan/Propeller-Type
Turbine Studies) depicts the summary of mortality rates for the Holt Project. When turbine
mortality rates were applied to the estimates of fish entrainment (Table 14, Estimated Annual
Total Number of Potentially Entrained Fish Killed Due to Turbine Mortality at the Holt Project),
a total of 66,768 fish are estimated to be killed annually due to turbine mortality.
Table 15 (Annual Size Composition of Fish Killed by Family/Genus Groups) depicts the total
number of fish in each family group and length group estimated to be killed annually and for
each season.
4.0 DISCUSSION
The methodology used in this entrainment and turbine mortality study was based on similar
approaches used in other hydro relicensings and incorporated data from numerous FERC-
accepted studies. The study plan was developed with the input of Holt Stakeholders.
This report provides order-of-magnitude estimates of potential fish entrainment and turbine
mortality at the Holt Project. The results of this study will be used in the preparation of the Holt
Final License Application.

FISH ENTRAINMENT AND TURBINE MORTALITY STUDY PLAN
HOLT HYDROELECTRIC PROJECT
FERC NO. 2203
ALABAMA POWER COMPANY BIRMINGHAM, ALABAMA
GOALS AND OBJECTIVES OF THE STUDY
Operation of hydroelectric projects can result in the sporadic entrainment of fish into the Project
turbine. Passage through the turbines can result in some degree of mortality as well as movement
of fish from the Project reservoir downstream. The Alabama Department of Conservation and
Natural Resources (ADCNR) and U.S. Fish and Wildlife Service (USFWS) would like to
understand the potential impacts of entrainment and turbine mortality on fish that pass through
the Holt Project turbine.
RELEVANT RESOURCE MANAGEMENT GOALS
The ADCNR is charged with the regulation of recreational fishing in the Black Warrior River.
The ADCNR currently and historically has stocked hybrid striped bass into Holt Reservoir for
recreational fishing purposes. Knowledge of Project impacts to the local fishery associated with
entrainment and turbine mortality may allow them to adjust their management strategies of the
Holt Reservoir fishery.
BACKGROUND AND EXISTING INFORMATION
Over fifty site-specific studies of resident fish entrainment at hydroelectric sites in the United
States have been performed and reported on to date. These studies provide order-of-magnitude
estimates of annual fish entrainment (FERC, 1995). Along with the entrainment data, descriptive
information has also been gathered from each entrainment study and includes:
• Location: geographical proximity, river basin; • Project size: discharge capacity and power production; • Project operation: e.g., peaking run-of-river, etc.; • Biological factors: fish species composition; • Impoundment characteristics: general water quality, impoundment size, flow regime; and • Physical project characteristics: trash rack spacing, intake velocity, etc.
2
Extensive turbine mortality study data exists for a range of turbine types and physical
characteristics, which can be compared to the Holt Project turbine. These characteristics are
commonly attributed to turbine passage mortality (Cramer and Oligher, 1963; Bell, 1991; Eicher,
1987; EPRI, 1992). Descriptive data includes:
• Turbine design type; • Operating head; • Runner speed; • Diameter; and • Peripheral runner velocity.
Alabama Power will provide the descriptive data listed above for the Holt Project as well as
comparisons to similar projects.
Current information for Holt Reservoir fishery is available through the ADCNR Reservoir
Management Reports. The ADCNR has also provided a list of species that they believe may
inhabit the Holt Reservoir. Similar study information performed during Alabama Power’s
relicense of the Bankhead Development (located upstream on the Black Warrior River) is also
available for use (Alabama Power, 2003).
PROJECT NEXUS
The study will estimate the magnitude of impacts related to fish entrainment and turbine
mortality related to existing operation of the Holt Project.
STUDY AREA AND STUDY SITES
The study area for this issue will include the intake area of the Holt Project.
PROPOSED METHODOLOGY
The methodology for this study will involve developing an estimate of the magnitude of
entrainment and turbine mortality for the Holt Project through the performance of a Desktop
Entrainment Analysis. The methodology for this study follows standard methods previously
accepted by FERC or standard methodologies used by the Fisheries Management community.
3
DESKTOP ENTRAINMENT STUDY METHODS
Define the Entrainment Database
For this study, fish entrainment information from other hydroelectric projects will be assembled
into a database for analyzing the magnitude of potential entrainment. After review of the
database, the most similar projects will be selected and used to develop a Holt entrainment
estimate.
Calculate an Estimated Fish Entrainment Rate
The entrainment rate information from the selected entrainment studies will be consolidated to
develop fish entrainment rates for the Holt Project. The entrainment rates will be presented in
fish entrained by volume of water passed through the Project turbine (fish/million cubic feet).
The data will be grouped by season where appropriate to determine an entrainment rate for each
season of the year. The seasonal data will be used to develop an estimated seasonal mean
entrainment rate for the Holt Project.
Estimate Species Composition and Length Frequency Distribution
The species composition data from the Warrior Entrainment Study (Alabama Power, 2003), in
conjunction with ADCNR data for Holt Lake, will be used to develop species composition for
entrainment. The total number and total length (Length frequency) of fish entrained will be based
on information available from the entrainment database.
Estimate of Turbine Mortality
As fish move through hydroelectric turbines, a percentage are killed due to blade strikes, shear
forces, and pressure changes. Turbine passage survival studies have been performed at numerous
hydroelectric projects throughout the country. Characteristics of these projects will be compared
to the characteristics of the Holt Project and suitable studies will be selected for the transfer of
turbine mortality data for each development. Selected turbine survival rate data will be obtained
from the literature and used to estimate the number of fish killed due to turbine mortality. The
following turbine characteristics will be used as criteria for use in this analysis:
• Turbine design type; • Operating head; • Runner speed;
4
• Turbine diameter; • Blade number and spacing; and • Peripheral runner velocity.
To the extent possible, turbine mortality rate data available from source studies will be related to
the species and size class of fish estimated to be entrained at the Holt Project. Where multiple
tests are available for a given species and size class, a mean survival rate will be computed. For
species and size classes where no applicable data can be found or accepted, the survival rate
reported for a similar species and size class will be substituted.
Once turbine mortality rates are developed from the study database, the rates will be applied to
the entrainment estimates for the Holt Project. This will be accomplished by multiplying fish
entrainment estimates by the composite mortality rates for each species or family group and size
class (where applicable).
Filters
Due to certain site-specific characteristics of the Holt Project, it may be necessary to adjust
entrainment estimates. Factors affecting entrainment rates that may warrant investigation for
adjustment of estimates include:
• Stratification at the intakes (dissolved oxygen); • Intake velocities; • Fish habitat available at the intakes; and/or • Other factors identified during the study that may affect entrainment rates.
CONSISTENCY WITH GENERALLY ACCEPTED SCIENTIFIC PRACTICE
This study employs generally accepted practices for evaluating fish entrainment and turbine
mortality at hydroelectric projects. The study methodology is consistent with generally accepted
fishery sampling principles and practices.

PRODUCTS
Data and analyses from this study will be included in a report to the ADCNR, USFWS, and
interested stakeholders. A draft report will be distributed for review and comment within 6
months of completion of the analysis. A final report will be provided as part of the draft license
application that will include raw data in tabular form, analysis performed, and results and
discussion.
SCHEDULE
This draft schedule generally corresponds to Alabama Power’s Process Plan and Schedule filed
with FERC as part of the PAD on August 27, 2010.

1.0 TOWNSEND DAM ENTRAINMENT STUDY
1.1 SITE DESCRIPTION
The Townsend Dam Project is located in Fallston and New Brighton, Pennsylvania on the
Beaver River, an Ohio River tributary that has a drainage area of approximately 3,100 square
miles. The Project has a rated head of 16 feet and operates in a run-of-river mode using two
Kaplan (propeller turbines). The Beaver River fisher consists of a mixture of warm and cool
water species, including freshwater drum.
1.2 STUDY DESCRIPTION
Full recovery entrainment netting was performed on Unit 2 at the Townsend Dam Project. The
unit was sampled for 24 hours three times per month in January – August 1992, July 1993,
September – December 1993, and April 1994. Net efficiency tests resulted in relatively high
efficiencies (94% to 97%). A total of 392,023 fish were collected during sampling. The
entrainment sample was dominated by gizzard shad (99.4%). Freshwater drum comprised
approximately 0.15% of the sample.
2.0 OSWEGO PROJECT ENTRAINMENT STUDY
2.1 SITE DESCRIPTION
The Oswego Project is located in north-central New York State and is comprised of three
developments: Fulton, Minetto, and Varick. The Oswego River originates just downstream of
Oneida Lake at the confluence of the Seneca and Oneida Rivers. The Oswego River drainage
area is approximately 5,100 square miles. The projects are operated as storage-and-release
pulsing facilities. Entrainment netting was performed only at the Minetto site, which has a rated
head of 17.3 ft and five horizontal Francis turbines with combined hydraulic capacity of 7,500
cfs.
C-2
2.2 STUDY DESCRIPTION
Full recovery entrainment netting was performed for a 48 hour duration on units 3, 4, and 5 at the
Minetto development between May 1994 and April 1995 on a bi-weekly interval. Net efficiency
tests were conducted on each unit and used to adjust entrainment netting data to provide total
entrainment estimates for each unit. Data from the sampled units was used to estimate
entrainment at the unsampled units (Units 1 and 2). A total of 3,519,061 fish were estimated as
entrained at Minetto during the study. Gizzard shad were the dominant species, comprising 62%
of all entrainment at the site. Freshwater drum were estimated to comprise less than 0.001%.

As for the fishes, your analysis appears to be accurate and well written. However, I suggest APCo also consider freshwater mussels as possible victims of entrainment /impingement. Although it's not typically a factor considered at hydropower projects around the country, as it is not documented in FERC (1995), I do believe it should be considered in areas that support freshwater mussels. Since mussels are benthic animals, they, or their host fish species, have the potential to be entrained/impinged at the project intakes. For example, on June 14, 2005, a juvenile Alabama (=inflated) heelsplitter (Potamilus inflatus) was apparently impinged and removed from the trash racks at APCo's Greene County Steam Plant (GCSP). Although this might have been a rare incident, it still warrants consideration. Even though the inflated heelsplitter was not reported during your recent surveys, we do believe it occurs in the vicinity of the Holt Project. I recommend that a comparison of flow rates, screen size, and other pertinent information be conducted between GCSP and the Holt Project, and incorporated into this analysis. I also recommend using information provided in Table 6 of this analysis to estimate potential levels of mortality (i.e., “take”) for the Freshwater Drum (Aplodinotus grunniens), which is the known host fish for the inflated heelsplitter (Roe et al. 1997). Thanks again for the opportunity to review this study. If you have any questions, please let me know. jeff Federal Energy Regulatory Commission (FERC). 1995.

Jeff Powell Aquatic Biologist U.S. Fish and Wildlife Service Alabama Ecological Services Field Office ==================================== 1208-B Main Street Daphne, Alabama 36526 251.441.5858 http://daphne.fws.gov http://www.facebook.com/#!/usfwsalabama Alabama Power Response: Alabama Power respectfully disagrees with the US Fish and Wildlife Service (USFWS) assumption that individual mussels would be entrained at the Holt Project on a regular basis. We
base this assumption on the large physical differences between a cooling water intake and a hydropower intake. The cooling water intake at the Greene County Steam Plant is located at the terminus of a 600 foot long intake canal from Demopolis Reservoir on the Black Warrior River. The intake area is separated into three bays approximately 11 feet wide by 32 feet tall. Water is withdrawn from the surface to bottom of the structures and studies by Alabama Power reported that the maximum intake capacity for this structure is 673 cfs with an intake velocity of 1.34 ft/sec at the intake screens. Therefore the flow in the intake canal is relatively slow and the canal could likely become inhabited by mussels. The Holt intake is located in the main channel of the Warrior River. The depth of the forebay is approximately 75 feet deep and the penstock is approximately 81.5 feet wide by 40 feet deep. Flows enter the penstock from the surface to approximately 15 feet above the substrate. The turbine has a minimum hydraulic capacity of 1,000 cfs, and maximum hydraulic capacity of 11,200 cfs with a maximum intake velocity of approximately 4 ft/sec. Because the penstock intake is more surface oriented, the probability of entraining a mussel is not as likely as a cooling water intake. Hydropower sites do not typically have bio-fouling as a result of mussels or clams and none have been noted at the Holt facility. Also as USFWS notes, the inflated heelsplitter was not detected in the vicinity of the Holt Project. Although they may be present in the system, their population densities are apparently very low, which would also diminish their chances of entrainment. Estimates of turbine mortality for freshwater drum are presented in Table 15 of the Holt Entrainment Report. The study estimated that approximately 438 freshwater drum are killed by turbine mortality at the Project annually. From: "Greene, Chris" <[email protected]<mailto:[email protected]>> Date: December 16, 2011 3:42:19 PM CST To: "Powers, Jason" <[email protected]<mailto:[email protected]>> Cc: "Cook, Stan" <[email protected]<mailto:[email protected]>>, "'[email protected]<mailto:[email protected]>'" <[email protected]<mailto:[email protected]>>, "Haffner, Jay" <[email protected]<mailto:[email protected]>> Subject: RE: Draft Holt Fish Entrainment and Turbine Mortality Study Jason, The Alabama Department of Conservation and Natural Resources (Fisheries Section) has reviewed the Draft Holt Fish Entrainment and Turbine Mortality Study and provides the following comments:
1) The Family Moronidae (white bass, hybrid striped bass, and striped bass) is missing from Table 2.
Alabama Power Response: Alabama Power reviewed Table 2 to determine the inconsistency. On February 28, 2011, the ADCNR (Chris Greene & Andrew Henderson) provided a table of species that should be present at the Holt site. The family Moronidae was not in that table. However, ADCNR (Chris Greene)
commented on May 31, 2011 that ADCNR has historically stocked hybrid striped bass in the Holt reservoir. We did include Moronidae in the entrainment and mortality calculations but inadvertently left them out of Table 2. Table 2 has been corrected.
2) Coosa Bass is incorrectly listed under the Moronidae Family in Table 3. Redeye bass (aka Coosa Bass) is already listed under the Family Centrarchidae.
Alabama Power Response: We have made that correction and rechecked the table for calculations.
3) The family Percidae is misspelled as Perdidae in Table 6.
Alabama Power Response: We have corrected this error.
4) Was the mortality rate (18.5%) for the Scianidae Family obtained from
actual field observations from the two studies or was this value obtained from substitute species data? It was observed that the mortality value for this family was exactly the same as for the Catostomidae Family.
Alabama Power Response: We have reviewed the data and determined that your assumption is correct. The mortality rate for the family Scianidae was a substitute value from the Catastomidae family, which we believe is close in morphology to the Scianids
5) The entrainment estimates for freshwater drum were obtained from two separate hydropower facilities, both of which are located in the northeast (NY and PA). Is this data actually comparable to the Holt Project, since the relative abundance of fish may be much different? Are there any other southern hydropower projects where freshwater drum entrainment rates could be obtained?
Alabama Power Response: We have used the best available information as the basis for our entrainment estimates. To the best of our knowledge, there are no other entrainment studies that we can use for the estimate of freshwater drum. If the ADCNR is aware of additional information, we will work with you to include that data into our estimates and the report. Thanks for the opportunity to comment on this draft study, J.
