This shapefile compares the approximate location of mangroves within the boundary of Ten Thousand Islands NWR in 2005 to their location in 2014.

This dataset consists of a detailed digital map and summary of irrigated acreage during the 2016 growing season developed for Polk County, Florida. Selected attribute data were collected for the irrigated areas, including crop type, primary water source, and type of irrigation system.

Water-level measurements of wells were taken in the Upper Floridan aquifer between the dates of May 2 and June 23, 2010. A GIS shapefile of these water-level measurements was constructed and released as part of a prior USGS publication (Kinnaman and Dixon, 2011). This ArcGIS layer was updated in August 2014 to include salinity-based density corrections to water levels in those areas of south Florida where water in the subject aquifer is not fresh. The density corrections to water levels result in the portrayal of the “equivalent freshwater head” values in brackish and saline areas of the Upper Floridan aquifer where water quality data were available.

This layer shows the potentiometric surface contours of the Upper Floridan Aquifer in Florida and parts of Georgia, South Carolina, and Alabama in May 2010. Contours were manually contoured from well elevation data collected in May-June 2010. This layer was updated in August 2014 to include south Florida by calculating the equivalant freshwater head where water quality data was available.

Groundwater basin divides within the Floridan Aquifer System include the Dougherty Plain Apalachicola, Southeast Georgia, Northeast Florida, South Carolina, Panhandle, Thomsville-Tallahasse Suwannee, West Central Florida, East Central Florida and South Florida.
