Comparison of Agricultural Water Use Estimates Available for the CFWI
Region
For the HAT
Current USGS ECFT Model MethodSJRWMD Annual Water Use Survey
SummariesUSGS Water Use Surveys for 1995,
2000, 2005SJRWMD - CFCA Historic Agricultural
Estimation Project developed for USGS ANN
Available Data for Estimated Agricultural Water Use
AFSIRS based for SJR and SF. (SWF Not estimated and uses metered data)
Incorporates Land Use Flux Code information for agriculture for SJR and SF to identify irrigated parcels for 1995, 2000, and 2005. SJR locations were verified in 2005 for crop type and irrigation
method Uses daily RADAR Rainfall and GOES ET data that was substituted
for the long term climate data in the AFSIRS model Monthly AFSIRS quantities were adjusted with Bench Mark Farms
application rates for several crop types to reflect metered data Tables were developed to adjust AFSIRS rate to BMF rates for
Ridge Citrus, Flatwoods Citrus, Leather leaf Fern, Nursery, Potatoes, Ferns, and Sod.
Well location were created for each model cell or cells that fell into the polygons identified in land use. Actual well locations were used for SWF only.
Daily irrigation quantities were created to be incorporated into the Green-AMPT for recharge calculations.
Current USGS ECFT Model Agricultural Estimates
Based on the Modifiled Blaney-Criddle model Uses long term climatic data available with the
MBC model Generalized county wide acreage estimates
provided by the Agricultural Extension agency Provides no monthly temporal data No spatial reference is provided other than
county level totals by crop
SJRWMD Annual Water Use Surveys
Published 5 year intervals County Totals Generally taken from WMDs Appears to have discrepancies with WMD
reported data Annual values provide no monthly temporal
data No spatial reference is provided other than
county level totals by crop
USGS Water Use Surveys
Historical evaluation for 1957 through 2010 Uses per acreage application rate estimates from NASS (for
citrus), USGS, and WMDs for other crops Polygons representing historic land cover from land use/land
cover data from USGS, WMDs, FGDL, and other GIS sources used then scale based on best acreage estimates from other sources (particularly NASS citrus acreage estimates)
The groundwater use estimates are then allocated to polygons based on proportional acreage. And although the exact polygon acreage of the GIS data is not the same as the acreages used to generate the groundwater use estimates, the final distribution of ground water use (on a semi-regional, county-wide scale) is assumed to be accurate based this proportional distribution
