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.

Custodian - Danny Layfield.The Northwest Florida Water Management District maintains the following GIS Data Dictionary as a public service, by granting the public and government agencies access to the Districts GIS data.Data is provided on an "as is" basis. 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.

Water Management Districts in Florida are mandated by the Florida Statutes to ensure adequate supply of water and water resources for all citizens and natural features, provide protection and improvement of natural systems and water quality, minimize harm to water resources, and promote the reuse of reclaimed water. Water Management Districts have the regulatory authority for well construction and consumptive use permitting. The Department of Environmental Protection has regulatory authority over wastewater facilities. Florida Water Management District Governing Board Boards are required to conduct regional water supply planning for areas where existing water sources are insufficient to meet projected 20-year demands. Those areas are also to be designated as Water Resource Caution Areas, either by rule if the district uses the designation in its consumptive use permitting program, or in its Regional Water Supply Plan if it does not. The Department uses the designation in wastewater facility permitting. Wastewater facilities within, discharging into, or serving a population within a Water Resource Caution area are required to conduct a reuse feasibility study in order to obtain a permit.For more information follow these links:Florida Office of Water Policy https://floridadep.gov/water-policy Water Management Districts http://www.nwfwmd.state.fl.us, http://www.srwmd.state.fl.us, http://www.sjrwmd.com, http://www.swfwmd.state.fl.us, http://www.sfwmd.gov Section 40A-2.801 FAC http://florida.eregulations.us/rule/40a-2.801

[DOWNLOAD ONLY] These hydrogeologic data for the Lower West Coast of Florida and were compiled in support of the Lower West Coast Water Supply Planning effort documented in Technical Publication WS-35, Hydrogeologic Unit Mapping Update for the Lower West Coast Water Supply Planning Area, August 2015. The objectives of this study were to create regional hydrogeologic maps including contour maps showing unit surfaces and thicknesses, and cross-sections representative of both the surficial aquifer system (SAS) and intermediate aquifer system (IAS). The maps, source data, and metadata used to generate these products are archived in a manner suitable for model implementation and regulatory use in a publicly accessible format. The results will be incorporated into the forthcoming Lower West Coast Surficial Aquifer System and Intermediate Aquifer System Model (LWCSIM), which will evaluate the potential impact of existing and projected groundwater withdrawals in all SAS and IAS aquifers within the region over the next several decades. For full documentation, please see Technical Publication WS-35, "Hydrogeologic Unit Mapping Update for the Lower West Coast Water Supply Planning Area," dated August 2015 by Elizabeth Geddes, Emily Richardson P.G., and Anne Dodd P.G., Water Supply Bureau, Water Resources Division, South Florida Water Management District, West Palm Beach, Florida.

This dataset, created by the Florida Department of Environmental Protection's Office of Watershed Services within the Division of Environmental Assessment and Restoration, is an inventory of Land use - Land Cover classified in the State of Florida's Suwannee River Water Management District and based on 2013 or 2014 True color photography. Classifications are provided for level 1, 2, 3 and a few level 4 (indicated in Land Use and Land Cover Code fields) land uses. Please reference the metadata for contact information.

This data set serves as documentation of land cover and land use (LCLU) within the South Florida Water Management District as it existed in 2017-19. Land Cover Land Use data was updated from 2014-16 LCLU by photo-interpretation from 2017-19 aerial photography and classified using the SFWMD modified FLUCCS classification system. Features were interpreted from the county-based aerial photography (4 in - 2 ft pixel), see imagery year in the "AERIAL DATE" field. The features were updated on screen from the 2014-16 vector data. Horizontal accuracy of the data corresponds to the positional accuracy of the county aerial photography. The minimum mapping unit for classification was 0.5 acres for wetlands and 5 acres for uplands. This data is partial and is not considered complete until the entire SFWMD has been completed.Photointerpretation Key: https://geoext.geoapps.sfwmd.gov/TPubs/2014_SFWMD_LULC_Photointerpretation_Key.pdf

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.

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 2019.

[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.

Potentiometric surface maps for the Floridan Aquifer created by the USGS Water Resources Division for the Southwest Florida Water Management District. This service is for the Open Data Download application for the Southwest Florida Water Management District.

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).

The map report shows the potentiometric surface of the Upper Floridan aquifer measured in September 2007. 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 wet season, when ground-water levels usually are at an annual high and withdrawals for agricultural use typically are low. The cumulative average rainfall of 39.50 inches for west-central Florida (from October 2006 through September 2007) was 13.42 inches below the historical cumulative average of 52.92 inches (Southwest Florida Water Management District, 2007). 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 September 17-21, 2007. 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 Orlando, Florida (Kinnaman and Dixon, 2008). 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 high water-level condition.
