The Cape Fear and Pee Dee River Basins in North Carolina and South Carolina were 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 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 to provide information related to the competing societal and ecological water needs in the Southeastern Atlantic Coastal Basins of the Carolinas. The Coastal Carolinas study area includes the Pee Dee and Cape Fear River...
A new method for frequency analysis of hydrologic time series was developed to facilitate the estimation and reconstruction of individual or groups of frequencies from hydrologic time-series and facilitate the comparison of these isolated time-series components across data types, between different hydrologic settings within a watershed, between watersheds, and across frequencies. While climate-related variations in inflow to and outflow from aquifers have often been neglected, the development and management of ground-water and surface-water resources has required the inclusion of the assessment of the effects of climatic variability on the supply and demand and sustainability of use. The regional assessment of climatic...

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.

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...

During 2014, the U.S. Geological Survey and other agencies made approximately 1,026 water-level measurements in the Mojave River and Morongo groundwater basins. These data document recent conditions and, when compared with previous data, changes in groundwater levels. A water-level contour map was drawn using data from about 610 wells, providing coverage for most of the basins. Twenty-four hydrographs show long-term (1930-2014) water-level conditions throughout the basins, and 9 short-term (1992 to 2014) hydrographs show the effects of recharge and discharge along the Mojave River. In addition, a water-level-change map was compiled to compare was compiled to compare the 2014 water levels to the 2012 water levels...

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.
