Shapefile: Potentiometric wells for the Upper Floridan aquifer in Florida and parts of Georgia, South Carolina, and Alabama, May-June 2010 – Updated
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.
Estimated Groundwater Withdrawals for the Coastal Carolinas Focus Area Study by MODFLOW Model-Cell Area, Year, and Water-Use Category, 1974 - 2015
The coastal region which includes areas within the Pee Dee, Cape Fear, and Neuse-Pamlico River Basins in South Carolina and North Carolina was chosen as a focus area study (FAS) for the U.S. Geological Survey (USGS) National Water Census (NWC) in 2016. The objective of the NWC is to place technical information and tools in the hands of stake holders so that they can make informed decisions on water availability. The USGS South Atlantic Water Science Center, comprised of North Carolina, South Carolina, and Georgia, conducted a 3-year study of water use and availability, climate change, and population growth to provide information related to the competing societal and ecological water needs in the Southeastern Atlantic...
Shapefile: Potentiometric surface contours for the Upper Floridan aquifer in Florida and parts of Georgia, South Carolina, and Alabama, May-June 2010 – Updated
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.
Shapefile: Groundwater basin divides for the Upper Floridan aquifer in Florida and parts of Georgia, South Carolina, and Alabama, May-June 2010 – Updated
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.
