South Atlantic Water Science Center (SAWSC)
Home
Our Center's priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and community. Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices.
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 SAWSCScience at SAWSC
The South Atlantic Water Science Center collects high-quality hydrologic data and conducts unbiased, scientifically sound research on Georgia's, North Carolina's, and South Carolina's water resources.

Nitrogen in the Chesapeake Bay watershed—A century of change, 1950–2050
ForewordSustaining the quality of the Nation’s water resources and the health of our diverse ecosystems depends on the availability of sound water-resources data and information to develop effective, science-based policies. Effective management of water resources also brings more certainty and efficiency to important economic sectors. Taken...

Technical note—Relative variability of selected turbidity standards and sensors in use by the U.S. Geological Survey
The challenges associated with field measurements of turbidity are well known and result primarily from differences in reported values that depend on instrument design and the resulting need for reporting units that are specific to those designs. A critical challenge for making comparable turbidity measurements is the selection and use of...

Development of regression equations for the estimation of the magnitude and frequency of floods at rural, unregulated gaged and ungaged streams in Puerto Rico through water year 2017
The methods of computation and estimates of the magnitude of flood flows were updated for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent chance exceedance levels for 91 streamgages on the main island of Puerto Rico by using annual peak-flow data through 2017. Since the previous flood frequency study in 1994, the U.S. Geological Survey has...
