Overview
Lake Hartwell is a major reservoir located along the border of South Carolina and Georgia within the upper Savannah River basin. Formed by the construction of the Hartwell Dam on the Savannah River and fed primarily by the Tugaloo and Seneca rivers, the lake was completed in 1962 and covers approximately 56,000 acres. Managed by the U.S. Army Corps of Engineers, Lake Hartwell serves as an important source of flood control, hydroelectric power generation, water supply, and recreation throughout the Southeast.
The reservoir features more than 900 miles of shoreline, creating a diverse landscape of wooded coves, creek arms, open-water basins, submerged timber, offshore points, and defined river channels. Water depths and bottom composition vary considerably throughout the lake, providing a wide range of aquatic habitats while also creating numerous navigation and fishing opportunities. The combination of protected tributaries and expansive main-lake areas makes Hartwell one of the most geographically diverse reservoirs in the region and a popular destination for both recreational boaters and tournament anglers.
Lake Hartwell is widely known for its recreational boating and nationally recognized sport fishery. Anglers target largemouth bass, spotted bass, striped bass, hybrid striped bass, crappie, catfish, and several sunfish species throughout the year. Fisheries management and recreational boating regulations are supported by both the South Carolina Department of Natural Resources (SCDNR) and the Georgia Department of Natural Resources (Georgia DNR). Numerous public boat ramps, marinas, parks, campgrounds, and lakeside communities provide year-round access to the reservoir, drawing visitors from across South Carolina, Georgia, and neighboring states.
Water levels on Lake Hartwell are actively managed by the U.S. Army Corps of Engineers as part of the larger Savannah River Basin system. Seasonal rainfall, drought conditions, hydropower generation requirements, downstream water-management needs, and flood-control operations can all influence lake elevations throughout the year. Because Hartwell is connected to other major reservoirs in the basin, including Lake Russell and Clarks Hill Lake (Lake Thurmond), reservoir operations are coordinated across the system to balance flood control, power generation, water supply, and recreation. Monitoring current lake levels is important for boating safety, fishing success, dock access, shoreline activities, and understanding changing reservoir conditions throughout the year.
