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.

When Rivers Rise: Warning You Before the Next Flood - A video by WECT TV, N.C., produced after Hurricane Matthew, showing USGS scientists demonstrating streamflow measuring techniques and showing "how a USGS streamgage works" and emphasizing the importance of streamgages and the need for measuring streamflow.
The passage of Hurricane Matthew during October 7–9, 2016, resulted in heavy rainfall that caused major flooding.
The peak stages and streamflows that occurred following Hurricane Matthew are documented in a USGS Open-File report published in December 2016 by the USGS South Atlantic Water Science Center.
The heavy rains and storm surge Hurricane Matthew produced caused severe flooding in many parts of the south east, resulting in almost 40 peak flood records. As the flood waters continue to recede from some affected areas, the U. S. Geological Survey will continue its efforts to record this historic flooding.

Characterization of sediment transport upstream and downstream grom Lake Emory on the Little Tennessee River near Franklin, North Carolina, 2014–15
Federal, State, and local agencies and organizations have expressed concerns regarding the detrimental effects of excessive sediment transport on aquatic resources and endangered species populations in the upper Little Tennessee River and some of its tributaries. In addition, the storage volume of Lake Emory, which is necessary for flood control...Huffman, Brad A.; Hazell, William F.; Oblinger, Carolyn J.
Widespread occurrence and potential for biodegradation of bioactive contaminants in Congaree National Park, USA
Organic contaminants with designed molecular bioactivity, such as pesticides and pharmaceuticals, originate from human and agricultural sources, occur frequently in surface waters, and threaten the structure and function of aquatic and terrestrial ecosystems. Congaree National Park in South Carolina (USA) is a vulnerable park unit due to its...Bradley, Paul M.; Battaglin, William A.; Clark, Jimmy M.; Henning, Frank; Hladik, Michelle; Iwanowicz, Luke; Journey, Celeste; Riley, Jeffrey W.; Romanok, Kristin
Hydrologic characterization of Bushy Park Reservoir, South Carolina, 2013–15
The Bushy Park Reservoir is a relatively shallow impoundment in a semi-tropical climate and is the principal water supply for the 400,000 people of the city of Charleston, South Carolina, and the surrounding areas including the Bushy Park Industrial Complex. Although there is an adequate supply of freshwater in the reservoir, taste-and-odor water-...Conrads, Paul A.; Petkewich, Matthew D.; Falls, W. Fred; Lanier, Timothy H.
