This layer covers the entire state of Florida. Aquifers are underground layers of rock and sand that hold water. These layers are made up of loosely packed sediments and layers of calcium-rich limestone and dolomite. In Florida, most of the population depends on the Upper Floridan aquifer for their drinking water. The Upper Floridan aquifer, which is the largest aquifer in the state, holds the ground water like a sponge. Holes in the rock that makes up the aquifer allow the water to move freely through it. The Upper Floridan aquifer stretches for 100,000 square miles beneath Florida and parts of Alabama, Georgia and South Carolina. This is an update to the recharg layer. This data layer illustrates the generalized recharge and discharge from the Floridian Aquifer System. This is used for resource management and cartographic purposes. The Southwest Florida Water Management District (District) manages the water resources for west-central Florida as directed by state law. The District encompasses roughly 10,000 square miles in all or part of 16 counties and serves a population of more than 5 million people. The goal of the District is to meet the water needs of current and future water users while protecting and preserving the water resources within its boundaries. 19960814 publication date Complete As needed -87.649218 -79.703948 31.032335 24.908286 None Discharge Recharge Floridan Aquifer System None Southwest Florida Water Management District SWFWMD Florida None These data were not collected under the supervision of a licensed Professional Surveyor and Mapper.

The final product was checked against the source material. The Mapping and GIS section of the Southwest Florida Water Management District corrected any errors found. There are no significant omissions. No formal accuracy assessment was completed. This map should be used for regional cartographic purposes only. This data is provided 'as is' and its vertical positional accuracy has not been verified by GeoPlan SWFWMD 19880101 Brooksville, FL SWFWMD Additional Information: 1-888-ASK-USGS 1000000 onLine 20031205 publication date SWFWMD Spatial and Attribute Information The source map was tied down on a digitizing board using nine county-corner tics within the State of Florida as control points. The features were digitized using ArcEdit and topology was generated using the ArcInfo BUILD or CLEAN command. Attribute items were a added to the feature attribute tables and the appropriate attribute updated using ArcEdit. recharge 19941001 Southwest Florida Water Management District Mapping and GIS Section mailing and physical

Brooksville FL 34604-6899 (352) 796-7211 (352) 540-6018 8:00 a.m. to 5:00 p.m. In November and December 2003, an enterprise geodatabase was designed and implemented. Coverages were converted into feature classes using ArcCatalog 8.3. The feature classes were created new in a feature dataset, with column names, shape type, grid size, and projection information defined during creation. An X/Y Domain and Precision were set at MinX: -700,000; MinY: 2,000,000; Precision: 1000. Z-Values were set at MinZ: -20; Precision: 1000. The Grid Tile Size is 2,147,483.465. Data was then loaded into the feature classes from the coverages using the 'Load Data' tool in ArcCatalog 8.3. Indexes were created for attributes when there were more than 100 records in the data set. Topology and attributes were validated whenever possible. Positional Accuracy for topology rules used for positional validation. The following Topology Rules were created and validated for the feature classes in the Recharge feature dataset: Florida Recharge regions must not overlap. Florida Recharge boundaries must not self-overlap. Florida Recharge boundaries must be covered by boundary of Florida Recharge regions. Florida Recharge regions must be covered by Florida Recharge boundaries. The Cluster Tolerance was defined to be 0.005 meters. Any errors that were found were inspected and corrected using ArcMap 8.3. 20031205 Southwest Florida Water Management District Mapping and GIS Section mailing and physical

The data downloaded was in shapefile format packaged together in a zip file called flrecharge.exe. The shapefile was extracted and originally named: FLORIDANRECHARGE The data was in the following projection: NAD_1983_HARN_StatePlane_Florida_West_FIPS_0902_Feet The following tasks were undertaken: - Reprojected to the FGDL Albers NAD83 HARN projection. - All records were uppercased. - Changed original layer name from FLORIDANRECHARGE to RCHARG_DEC03 . - Dropped the OBJECTID, SHAPE.AREA, and SHAPE.LEN fields. - Added the DESCRIPT field based on FLORIDANRE - Added the FGDLAQDATE based on the date GeoPlan acquired the data from the source 20110203 Data imported to ArcSDE and exported as a shapefile.

A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.
