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.

Video - When rivers rise: warning you before the next flood (WCET TV, N.C.)
February 9, 2017

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. Click here to learn more about the work the USGS has completed for Hurricane Matthew.

Low-Flow Characteristics of Streams in South Carolina

An ongoing understanding of streamflow characteristics of the rivers and streams in South Carolina is important for the protection and preservation of the State’s water resources. Information concerning the low-flow characteristics of streams is especially important during critical flow periods, such as during the historic droughts that South...

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...
