South Atlantic Water Science Center (SAWSC)
We monitor hydrologic conditions so you can make informed decisions
Our scientists operate state-of-the-art data networks that provide spatially-consistent data to compare to historical trends.Find out more
Welcome to USGS South Atlantic Water Science Center's (SAWSC) Website. We offer information on streamflow, water quality, water-use, and groundwater data for Georgia, North Carolina, and South Carolina. We conduct hydrologic investigations and research projects. These data and information are the product of joint endeavors between the USGS and cooperators.
Hydrologic Data at SAWSC
We provide current and historical surface-water, groundwater, water quality, water use, and ecological data in various formats (map, graphical, tabular).Water Data at SAWSC

After Hurricane Irma, eight USGS field crews traveled around the Jacksonville, Tampa and Fort Myers areas last week looking for evidence that tell scientists how high the flood waters and storm surge from Hurricane Irma reached.
A recent study led by the U.S. Geological Survey in cooperation with the National Park Service found dozens of contaminants within the protected areas of Congaree National Park in South Carolina.
WINK TV in Fort Meyers, Florida follows a crew from the U.S. Geological Survey as they document how high water got during Hurricane Irma.
Monitoring storm tide and flooding from Hurricane Matthew along the Atlantic coast of the United States, October 2016
IntroductionHurricane Matthew moved adjacent to the coasts of Florida, Georgia, South Carolina, and North Carolina. The hurricane made landfall once near McClellanville, South Carolina, on October 8, 2016, as a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale. The U.S. Geological Survey (USGS) deployed a temporary monitoring network...Frantz, Eric R.; Byrne,, Michael L.; Caldwell, Andral W.; Harden, Stephen L.
Simulation of groundwater flow and pumping scenarios for 1900–2050 near Mount Pleasant, South Carolina
Groundwater withdrawals from the Upper Cretaceous-age Middendorf aquifer in South Carolina have created a large, regional cone of depression in the potentiometric surface of the Middendorf aquifer in Charleston and Berkeley Counties, South Carolina. Groundwater-level declines of as much as 249 feet have been observed in wells over the past 125...Fine, Jason M.; Petkewich, Matthew D.; Campbell, Bruce G.
Simulated effects of Lower Floridan aquifer pumping on the Upper Floridan aquifer at Barbour Pointe, Chatham County, Georgia
Steady-state simulations using a revised regional groundwater-flow model based on MODFLOW were run to assess the potential long-term effects on the Upper Floridan aquifer (UFA) of pumping the Lower Floridan aquifer (LFA) at well 36Q398, located at Barbour Pointe in coastal Georgia near Savannah. Simulated pumping of well 36Q398 at a rate of 750...Cherry, Gregory S.; Clarke, John S.
