Lake Marion is the largest lake in South Carolina. It is centrally located. Parts of it are in five different counties. The lake is referred to as South Carolina's inland sea. It has a 315-mile (507-kilometre) shoreline. It covers almost 110,000 acres (450 square kilometers or 173.7 square miles) of rolling farmlands, former marshes, and river valley landscape.
The Santee River was dammed in the 1940s to supply hydroelectric power. This was part of the rural electrification efforts initiated under President Franklin D. Roosevelt's New Deal during the Great Depression. It is one of the fifty largest lakes in the United States, whether natural or man-made reservoirs. It covers only about a third of the area of the fifteenth largest in size.
