These GIS data depict navigational routes commonly used in Florida. Many of these routes are officially designated navigational channels or waterways. Others are just well known but unmarked pathways from one location to another. These data were digitized from NOAA Nautical charts (image files) of various dates and map scales, using most detailed charts for the area and feature of interest. Where depicted on the charts, channel centerlines and waterway routes were followed. Otherwise, AToNs depicted on the charts were used as guides to trace navigation pathways. This data set does not depict all navigational pathways but should serve as a start to a more comprehensive data set.

SFWMD has compiled this dataset from information submitted by the utilities and verified by staff. This data is updated by SFWMD's water supply planning regions in 5 year cycles. Utility service area boundaries may also receive updates during the annual WaSUP process implemented by the Water Supply Bureau. The primary purpose of this dataset is to determine current population and associated water use demands, and to prepare maps in support of Water Supply Plan updates for the South Florida Water Management District's five regional planning areas (Lower West Coast, Upper East Coast, Lower East Coast, Lower Kissimmee Basin and the Central Florida Water Initiative (CFWI). Note, a utility may or may not have a larger permitted area/franchise area than the actual areas currently served. To view the full permitted boundaries, please refer to the SFWMD Regulation Water Use Permit datasets.

The South Florida Water Management District (SFWMD) and the U.S. Geological Survey (USGS) have evaluated projections of future droughts for south Florida based on climate model output from the Multivariate Adaptive Constructed Analogs (MACA) downscaled climate dataset from the Coupled Model Intercomparison Project Phase 5 (CMIP5).

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

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 release of data includes the chloride concentration of water samples provided by the USGS or other organizations that were used for this mapping effort. The inland extent of saltwater at the base of the Biscayne aquifer in the Model Land area of Miami-Dade County, Florida, was mapped in 2011. Since that time, the saltwater interface has continued to move inland. The interface is near several active well fields; therefore, an updated approximation of the inland extent of saltwater and an improved understanding of the rate of movement of the saltwater interface are necessary. A geographic information system was used to create a map using the data collected by the organizations that monitor water salinity in this area. A rate of saltwater interface movement of 140 meters per year was estimated by dividing the distance between two monitoring wells (TPGW-7L and Sec34-MW-02-FS) by the travel time. The travel time was determined by estimating the dates of arrival of the saltwater in ...

A Geographic Information System (GIS) shapefile and summary tables of irrigated agricultural land-use are provided for the 15 counties fully within the Northwest Florida Water Management District (Bay, Calhoun, Escambia, Franklin, Gadsden, Gulf, Holmes, Jackson, Leon, Liberty, Okaloosa, Santa Rosa, Wakulla, Walton, and Washington counties). These files were compiled through a cooperative project between the U.S. Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Policy. Information provided in the shapefile includes the location of irrigated lands that were verified during field surveying that started in May 2021 and concluded in August 2021. Field data collected were crop type, irrigation system type, and primary water source used. A map image of the shapefile is also provided. Previously published estimates of irrigation acreage for years since 1982 are included in summary tables.

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.

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.

YOU WILL ONLY GET THE FILTERED DATA FROM THIS DOWNLOAD.Contour lines are created for the potentiometric surface of the upper Floridan aquifer from water level data submitted by the water management districts. The points associated with the water level data are added to Geostatistical Analyst and ordinary kriging is used to interpolate water level elevation values between the points. The Geostatistical Analyst layer is then converted to a grid (using GA Layer to grid tool) and then contour lines (using the Contour tool). Post editing is done to smooth the lines and fix areas that are hydrologically incorrect. The rules established for post editing are: 1) rivers intersecting the UFA follow the rule of V’s; 2) potentiometric surface contour line values don’t exceed the topographic digital elevation model (DEM) in unconfined areas; and 3) potentiometric surface contour lines don’t violate valid measured water level data. Errors are usually located where potentiometric highs are adjacent to potentiometric lows (areas where the gradient is high). Expert knowledge or additional information is used to correct the contour lines in these areas. Some additional data may be river stage values in rivers that intersect the Floridan aquifer or land elevation in unconfined areas. Contour lines created prior to May 2012 may be calculated using a different method. The potentiometric surface is only meant to describe water level elevation based on existing data for the time period measured. The contour interval for the statewide map is 10 feet and is not meant to supersede regional (water management district) or local (city) scale potentiometric surface maps.

This dataset is a subset (containing records of the dams present in the state of Florida) of The National Inventory of Dams. Congress first authorized the US Army Corps of Engineers to inventory dams in the United States with the National Dam Inspection Act (Public Law 92-367) of 1972. The NID was first published in 1975, with a few updates as resources permitted over the next ten years. The Water Resources Development Act of 1986 (P.L. 99-662) authorized the Corps to maintain and periodically publish an updated NID, with re-authorization and a dedicated funding source provided under the Water Resources Development Act of 1996 (P.L. 104-3). The Corps also began close collaboration with the Federal Emergency Management Agency (FEMA) and state regulatory offices to obtain more accurate and complete information. The National Dam Safety and Security Act of 2002 (P.L. 107-310) reauthorized the National Dam Safety Program and included the maintenance and update of the NID by the Corps of Engineers. The most recent Dam Safety Act of 2006 reauthorized the maintenance and update of the NID. The NID consists of dams meeting at least one of the following criteria; 1) High hazard classification - loss of one human life is likely if the dam fails, 2) Significant hazard classification - possible loss of human life and likely significant property or environmental destruction, 3) Equal or exceed 25 feet in height and exceed 15 acre-feet in storage, 4) Equal or exceed 50 acre-feet storage and exceed 6 feet in height. The goal of the NID is to include all dams in the U.S. that meet these criteria, yet in reality, is limited to information that can be gathered and properly interpreted with the given funding. The Inventory initially consisted of approximately 45,000 dams, which were gathered from extensive record searches and some feature extraction from aerial imagery. Since continued and methodical updates have been conducted, data collection has been focused on the most reliable data sources, which are the various federal and state government dam construction and regulation offices. In most cases, dams within the NID criteria are regulated (construction permit, inspection, and/or enforcement) by federal or state agencies, who have basic information on the dams within their jurisdiction. Therein lies the biggest challenge, and most of the effort to maintain the NID; periodic collection of dam characteristics from 49 states (Alabama currently has no dam safety legislation or formal dam safety program), Puerto Rico, and 18 federal offices. The Corps resolves duplicative and conflicting data from the 68 data sources, which helps obtain the more complete, accurate, and updated NID.
