SOUTH-CAROLINA RESERVOIR REPORT

Last Updated: December 21, 2025

South Carolina has numerous small and large reservoirs and dams that play an important role in providing water for domestic, agricultural, and industrial purposes. Some of the major reservoirs in the state include Lake Marion, Lake Moultrie, Lake Murray, and the Jocassee Reservoir. These reservoirs are fed by various streams, rivers, and creeks, including the Savannah River, Catawba River, Broad River, and Saluda River. The hydrology of South Carolina is influenced by its location in the southeastern United States and its proximity to the Appalachian Mountains. The state receives ample rainfall throughout the year, with occasional drought conditions during the summer months. The mountains in the western part of the state contribute to snowpack, which can affect streamflow and reservoir levels during the spring and early summer. Record flooding has occurred in South Carolina in recent years, such as the 2015 floods that resulted in widespread damage and loss of life. In contrast, drought conditions have also been experienced, such as the severe drought in 2016 that led to water restrictions and low reservoir levels. Seasonal trends in streamflow and reservoir levels vary depending on rainfall patterns and other factors.
