Florida Water Management District Boundaries. This dataset, provided by DEP, shows the extent of all 5 Water Management Districts in Florida. It uses the old DEP Florida County Shoreline as an edge. Water management districts in the State of Florida work in collaboration with the Florida Department of Environmental Protection under the Florida Water Resources Act (Chapter 373, Florida Statutes). The water management districts and FDEP work together to resolve statewide water planning and management issues pertaining to water supply, flood protection, floodplain management, water quality, and protection of natural systems.

In no event will the District or its staff be liable for any direct, indirect, incidental, special, consequential, or other damages, including loss of profit, arising out of the use of these data even if the District has been advised of the possibility of such damages.The spatial datasets are provided as zipped (.zip) ESRI shapefiles or geodatabases. The data are provided in UTM Zone 16N / NAD 83, map units metershttp://www.nwfwmd.state.fl.us/data-publications/gis-mapping/gis-data-directorySRWMD: Hydrography basin major. USGS24"SBAS" was orginally created by USGS as part of a cooperative effort between the USGS and DEP to create a statewide basin or watershed map. SRWMD has modified and added some watersheds because of local knowledge and needs of the District. A number of items have also been added to the coverage. Surfacewater watersheds are topographic land features which contain a unique hydrologic area of surface drainage. Suwannee River Water Management has choosen to call this a watershed map instead of a basin map as previously called. These spatial data sets provide SRWMD and other government agencies with a consolidated resource for watershed information at various levels of geographic extent. The data sets are intended to support watershed analysis, planning, permitting, regulatory, and other functions at SRWMD. They have been edited and modified by the District to reflect better information available at the regional level, and to better meet the specific needs of the GIS users at SRWMD. A guide to the Watershed coverage is available from SRWMD at md_lib/basins/items.doc. A spreadsheet that expains the attribution of both the polygon and arc attribute tables is also located at md_lib/basins/sbas_items.doc.

It was created in Arc/Info, using the SJRWMD surface water drainage basins layer as a guideline. The swbasins were combined and shifted in places, to delineate ecology based areas for regulatory mitigation review. The changes came from a Board-appointed Advisory Committee and were approved by the Board and adopted by rule.The coverage corresponds to the basin boundaries found in the ERP Applicant's Handbook in Figure 12.2.8-1 and Appendix M. This is a special layer created specifically for regulatory purposes; it is distinct from the standard SJRWMD Surface Water Drainage Basins Layer. This layer mitig basin reg is to delineate ecologically based areas for regulatory mitigation review. This data reflects all Mitigation Basin changes approved by the Governing Board and effective as of November 5, 2008.For more information contact St. Johns River Water Management District 386-312-2314.http://floridaswater.com/gisdevelopment/docs/themes.htmlSWFWMD: This layer illustrates the extent of Comprehensive Watershed Management (CWM) watershed boundaries in the Southwest Florida Water Management District.

Land Use - Land Cover information provides environmental scientists an understanding of the relationships between human activities, land surface physiography and water resources. A copy of the 2015-2016 NWFWMD db was used as a base in conjunction with 2019 digital orthoimagery to update 2015-2016 database. The code 1700: Institutional code (Level 2), was down delineated into 8 new codes, being -- 1710: Education Facilities, 1720: Religious, 1740: Medical and Health Care, 1750: Governmental, 1760: Correctional, 1770: Other Institutional, 1780: Commercial Child Care, 1790: Institutional Under Construction. A number of modifications to existing code descriptions have also been made and these modifications can be found in the Photo Interpreter Key assigned to the 2019 data.Due to Hurricane Michael a new character, '9', has been added in the level 4 designation to indicate storm damage. This only pertains to select, mostly heavily vegetation codes or ones that show signs of vegetation damage. They include 2139, 2239, 2409, 2439, 3209, 3229, 3309, 4109, 4119, 4129, 4139, 4149, 4209, 4219, 4279, 4289, 4349, 4419, 4439, 6119, 6139, 6149, 6159, 6179, 6189, 6219, 6259, 6309, and 6469. The core codes of the delineated land use (or cover) have not been changed from their previous designation, we have just added the '9' designation to it. Determination of whether or not to keep the designation in the next update will be deliberated by the NWFWMD at that time.

This map presents the configuration of the bottom of the Floridan aquifer in the Southwest Florida Water Management District. The bottom of the aquifer generally corresponds to the beginning of consistent intergranular evaporites occurring in either the Avon Park, Lake City, or Oldsmar Limestones of Eocene age. The altitude of the bottom of the aquifer varies from about 600 feet below the National Geodetic Vertical Datum of 1929 in the north to about 3,000 feet below the datum in the South. (Kosco-USGS)

[DOWNLOAD ONLY] The South Florida Water Management District (District or SFWMD) and the U.S. Army Corps of Engineers have built six large treatment wetlands, referred to as Stormwater Treatment Wetlands (STAs), in the Everglades Agricultural Area (EAA) as part of a State and Federal initiative to protect the Everglades (Chimney and Goforth, 2001; Sklar et al., 2005). These treatment wetlands are intended to reduce high phosphorus concentrations in surface runoff coming from the EAA before this water reaches the northern portion of the present-day Everglades, i.e., the Water Conservations Areas. Each STA is subdivided into a number of treatment cells by interior levees.Treatment wetlands reduce the concentration of water-borne pollutants through natural bio-geochemical processes (Kadlec and Wallace, 2009). Wetland biogeochemistry, in turn, is intimately associated with the extent and condition of the wetland’s vegetation community (Reddy and DeLaune, 2009). Because of the important relationship between wetland treatment performance and vegetation, the vegetation communities in the STAs have been monitored throughout their operational histories. This effort was mandated as a condition of STA operating permits and by the Process Development and Engineering section of the District’s Long Term Plan (Burns & McDonnell, 2003).The vegetation communities in the STAs have been monitored using two different approaches: (1) vegetation maps were prepared for each STA based on the spatial distribution of different vegetation types interpreted from aerial photographs and (2) field surveys were conducted at a network of sites within each wetland to catalog plant taxa and assess vegetation areal coverage of the dominant taxa. The field-survey program was initiated as a cost-effective alternative to mapping for characterizing the plant community.For information about the imagery collection access this file: 2016 Imagery Collection in STAsFor details how the data was processed see the Lineage section.

The agreement also delegates to Broward County the compliance and enforcement of Environmental Resource Permitting (ERP), Dredge and Fill (DF) & Management and Storage of Surface Waters (MSSW) permits previously issued by DEP/SFWMD, Formal Wetland determinations, and specific variances for mixing zones, turbidity & dissolved oxygen (D.O.).Boundaries were compiled and published in 2016.https://floridadep.gov/ogc/ogc/content/operating-agreements

The Florida Water Resources Act, Chapter 373, F.S., establishes that all water in Florida, on the surface or in the ground, is a public resource managed by the department and the five water management districts. Water resource managers are tasked with the responsibility of balancing the needs of Florida's growing population with the needs of the natural systems by creating dynamic plans that appropriately allocate the state's limited water resources. Every five years, each district creates a Regional Water Supply Plan. Regional Water Supply Plans include a water supply and water resource development component; a funding strategy for water resource development projects; consideration of how the water supply development project options serve the public interest or save costs; technical data to support the plan; a list of water bodies for which minimum flows and levels have been established or will be established; recovery or prevention strategies for the water bodies not meeting their minimum flows and/or levels; and a list of water reservations. Without these planning efforts, the districts project that existing sources of water will not adequately meet the reasonable-beneficial needs for the next 20 years. For information on this program, see the Office of Water Policy's site at: https://floridadep.gov/water-policy/water-policy/content/water-supply.This data set presents the water supply planning regions of the five water management districts (WMDs) as of 2025. The location information was provided by the WMDs.

The U. S. Geological Survey (USGS) Airborne Height Finder (AHF) system was used to perform topographic surveys in Water Conservation Areas 2 and 3A. The AHF is a helicopter-based instrument that uses a GPS receiver, a computer, and a mechanized plumb bob to make measurements.

The Floridan aquifer system consists of the Upper and Lower Floridan aquifers separated by the middle confining unit. The middle confining unit and the Lower Floridan aquifer in west-central Florida generally contain highly mineralized water. The water-bearing units containing fresh water are herein referred to as the Upper Floridan aquifer. The Upper Floridan aquifer is the principal source of water in the Southwest Florida Water Management District and is used for major public supply, domestic use, irrigation, and brackish water desalination in coastal communities (Southwest Florida Water Management District, 2000).

This map report shows the potentiometric surface of the Upper Floridan aquifer measured in May 2006. The potentiometric surface is an imaginary surface connecting points of equal altitude to which water will rise in tightly-cased wells that tap a confined aquifer system (Lohman, 1979). This map represents water-level conditions near the end of the dry season, when ground-water levels usually are at an annual low and withdrawals for agricultural use typically are high. The cumulative average rainfall of 50.23 inches for west-central Florida (from June 2005 through May 2006) was 2.82 inches below the historical cumulative average of 53.05 inches (Southwest Florida Water Management District, 2006). Historical cumulative averages are calculated from regional rainfall summary reports (1915 to most recent complete calendar year) and are updated monthly by the Southwest Florida Water Management District.

This report, prepared by the U.S. Geological Survey in cooperation with the Southwest Florida Water Management District, is part of a semi-annual series of Upper Floridan aquifer potentiometric-surface map reports for west-central Florida. Potentiometric-surface maps have been prepared for January 1964, May 1969, May 1971, May 1973, May 1974, and for each May and September since 1975. Water-level data are collected in May and September each year to show the approximate annual low and high water-level conditions, respectively. Most of the water-level data for this map were collected by the U.S. Geological Survey during the period May 15-19, 2006. Supplemental water-level data were collected by other agencies and companies. A corresponding potentiometric-surface map was prepared for areas east and north of the Southwest Florida Water Management District boundary by the U.S. Geological Survey office in Altamonte Springs, Florida (Kinnaman, 2006). Most water-level measurements were made during a 5-day period; therefore, measurements do not represent a "snapshot" of conditions at a specific time, nor do they necessarily coincide with the seasonal low water-level condition.

Water-Level Changes

Water levels in about 95 percent of the wells measured in May 2006 were lower than the May 2005 water levels (Ortiz and Blanchard, 2006). May 2006 water levels in 403 wells ranged from about 26 feet below to about 6 feet above May 2005 water levels (fig. 1). Significant water level declines occurred in eastern Manatee County, southwestern Polk County, southeastern Hillsborough County, and in all of Hardee County. The largest water level declines occurred in southwestern Hardee County. The largest water level rises occurred in south-central Pasco County, northeastern Levy County, northwestern Marion County, and along the gulf coast from Pasco County to Citrus County (fig. 1).

Water levels in about 96 percent of the wells measured in May 2006 were lower than the September 2005 water levels (Ortiz, 2006). May 2006 water levels in 397 wells ranged from about 31 feet below to 3 feet above the September 2005 water levels. The largest water level decline was in west-central Hardee County and the largest rise in water levels was in south-central Pasco County.

As included in this EnviroAtlas dataset, the community level domestic water use was calculated using locally available water use data per capita in gallons of water per day (GPD), distributed dasymetrically, and summarized by census block group. Domestic water use, as defined in this case, is intended to represent residential indoor and outdoor water use (e.g., cooking hygiene, landscaping, pools, etc.) for primary residences (i.e., excluding second homes and tourism rentals). For the purposes of this metric, these publicly-supplied estimates are also applied and considered representative of local self-supplied water use. Specific to Florida, oversight of water resources is handled by five water management districts, each comprised of a board of Governor-appointed volunteers. These Districts focus on water supply, flood protection, water quality, and natural system preservation. Tampa is in the Southwest Florida Water Management District (SWFWMD). Within the EnviroAtlas Tampa boundary, there are 67 service providers with 2003-2007 estimates ranging from 59 to 230 GPD. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets).
