Lake Hartwell is one of the Southeast's largest and most popular public recreational lakes.  Built by the U.S. Army Corps of Engineers between 1955 and 1963 as part of a flood control and hydropower project.  The man-made lake borders Georgia and South Carolina on the Savannah, Tugaloo and Seneca rivers.  Extending 49 miles up the Tugaloo and 45 miles up the Seneca at normal pool elevation, Lake Hartwell comprises nearly 56,000 acres of water with a shoreline of 962 miles.  The entire Hartwell project contains 76,450 acres of land and water. The Hartwell was completed in 1963 at a cost of more than $89 million.
