Natural Features

Hartwell Lake is a man-made lake bordering Georgia and South Carolina on the Savannah, Tugaloo and Seneca Rivers. The dam and lake area boasts 8 campgrounds and 11 day-use facilities that are operated by the US Army Corps of Engineers. The Hartwell Project was originally authorized for hydro-power, flood control, and navigation. Later, recreation, water quality, water supply and fish and wildlife management were added. Surrounding vegetation allows for plenty of shade, and the 962 miles of shoreline provide numerous swimming beaches, picnic areas and boat ramps.
