Hartwell Dam is a large earthen dam located on the Savannah River in Georgia and South Carolina. Completed in 1962, it was built primarily for flood control, hydroelectric power generation, and recreation. The dam creates Hartwell Lake, which spans over 56,000 acres and provides various recreational opportunities such as fishing, boating, and camping. The dam is operated by the U.S. Army Corps of Engineers and plays a crucial role in managing water resources in the region. It helps maintain water levels, supports local ecosystems, and contributes to the economy through tourism and recreational activities.
