Lake Hartwell is a man-made reservoir bordering Georgia and South Carolina on the Savannah, Tugaloo, and Seneca Rivers. Lake Hartwell is one of the southeast's largest and most popular recreation lakes. The lake is created by Hartwell Dam located on the Savannah River seven miles below the point at which the Tugaloo and Seneca Rivers join to form the Savannah. Extending 49 miles up the Tugaloo and 45 miles up the Seneca at normal pool elevation, the lake 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. I-85 bisects Hartwell Lake and makes the area easily accessible to visitors.
