The WUP_Stations geodatabase is a compilation of permitted water use withdrawal stations throughout parts of Florida and Georgia developed by the SJRWMD Bureau of Engineering and Hydrologic Sciences. This is part of the Water Use Permit (WUP) project led by Tammy Bader and Yassert Gonzalez.
Note: Permit Type FW used to indicate artesian wells with the potential to flow at land surface. These wells may have had or may currently have flow control devices. Most of these wells were identified through a groundwater modeling data consolidation effort performed in 2006.

This layer maps aquaculture and livestock permits and estimated aquaculture or livestock water demand within Florida. Water demand estimates are based on disaggregating county-level totals to permits or LULC polygons based on location and permit size. County level totals for aquaculture are based on USGS data or metered pumpage reports, whichever is greater. County totals for livestock are based on the 2012 USDA Ag Census of animal inventories.
This layer maps irrigated cropland within Florida in 2018.
This layer maps irrigated cropland and non-irrigated agricultural areas in Florida for 2018.
This layer maps irrigated cropland within Florida in 2018 and projected irrigated cropland in 2020, 2025, 2030, 2035, 2040, and 2045. Additions and declines in irrigated areas are based on a combination of county-level trends in the ratio of irrigated to agricultural area (from USDA Ag Census data) and an empirical water demand model based on permit-level water use data from 2007-2018.
Statewide irrigation conservation estimates were developed from exponential trends in USDA Farm and Ranch Irrigation Survey reported irrigation intensity (water applied per area). Two exponential functions were developed from recent FRIS data (2003-2013) and the whole dataset (1978-2013) in order estimate conservation largely resulting from management changes (on newly irrigated lands or existing irrigated lands with microspray or drip systems) and to estimate a greater amount of conservation resulting from equipment and/or management improvements for other areas in the ILG. The statewide total conservation estimate is disaggregated at the polygon level based on the ratio of polygon-level irrigation demand to statewide irrigation demand. Statewide, the total conservation estimate approaches 7% of total irrigation demand by 2045. Everglades Agricultural Area polygons were assumed to not contribute to conservation.
This layer maps freeze protected polygons and expected freeze protection irrigation demand in millions of gallons per day (MGD). Primary data source is USGS GOES ET temperature data (1996-2018) for polygon-specific numbers of historical freeze events at locations in the 2018ILG. Future irrigated areas in the ILGs were used to estimate freeze protection demands through 2045. A 14-hour freeze event was assumed, with freeze protection water being applied at intensities based on irrigation system (0.07 in/hr for microspray and 0.2 in/hr for impact sprinkler). Freeze protection water was estimated for citrus, blueberries, strawberries, peaches, and ferns.
The groundwater flow models developed by and for SJRWMD incorporate the McDonald and Harbaugh (1988) modular, three-dimensional, finite-difference, groundwater flow model (MODFLOW) developed for the USGS. A number of criteria were considered in selecting MODFLOW. The ability to account for multiple aquifers and semiconfining units was a primary consideration. This ability was necessary to account for the interaction between the aquifers that comprise the Floridan aquifer system as well as the interaction between the Floridan aquifer system and the overlying surficial aquifer system. Other essential requirements included the ability to account for heterogeneity in the physical properties of the aquifers and semiconfining units of the Floridan aquifer system and of the upper confining unit; and the ability to represent complex lateral boundary conditions. In addition to meeting all of these criteria, MODFLOW is well documented and has been applied successfully in numerous other groundwater modeling studies.
