1 Comparison of Agricultural Water Use Estimates Available for the CFWI Region For the HAT

2  Current USGS ECFT Model Method  SJRWMD Annual Water Use Survey Summaries  USGS Water Use Surveys for 1995, 2000, 2005  SJRWMD - CFCA Historic Agricultural Estimation Project developed for USGS ANN Available Data for Estimated Agricultural Water Use

3  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

4  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

5  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

6  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 CFCA Historic Agricultural Estimation

27 Conclusion from Comparison of Water Use Estimates  Four Estimates are available  ECFT AFSIRS Method Falls into the Range of Estimates  ECFT AFSIRS is only Method to Incorporate Same Data Used in the ECFT Calibrated Model, All Other Methods Rely on Average Climate Data  ECFT AFSIRS Method Appears to Provide Reasonable Annual average application
