Gonthier, G.J., and Painter, J.A., 2020, Estimated Use of Water for Coastal Carolinas Focus Area Study: U.S. Geological Survey data release,


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 Coastal Basins [...]

The Coastal Carolinas Focus Area Study (CC FAS) will compile existing information, add new scientific data and interpretation, and develop tools to help address the current and future challenges that water managers and other stake holders face in the Atlantic Coastal Basins of the Carolinas. The study is divided into 5 main components: 1) Societal Water-Use Data Compilation and Refinement, 2) Land-Use, Population, Water-Use and Climate Change Scenarios, 3) Surface-Water Modeling, 4) Ecological Response Modeling, and 5) Groundwater Modeling. The intended uses of groundwater-use data, by groundwater model-cell area, are for inclusion of groundwater modeling activities in the project area.
