Clarks Hill, East Dam

Dive enthusiasts are drawn to its abundant offerings, including boating, swimming, and scuba diving.

When exploring Clark's Hill Lake, it's important to consider the various environmental conditions. The water temperature, depth, and the rocky descent to the shoreline are factors to keep in mind.

One notable attraction for divers is the sunken airplane located off the US 221 in Clarks Hill, McCormick County, South Carolina. The Mitsubishi MU-2B twin-engine turboprop aircraft was intentionally sunk on August 26, 1989, by the Augusta Dive Club, with the assistance and permission of the Army Corps of Engineers. Before submerging, the plane was prepared by removing any potential hazards to scuba gear, including insulation, hydraulic and fuel lines. While exploring this underwater relic, exercise caution due to its rough edges. Wearing gloves and avoiding contact with sharp objects is advised.

Clark's Hill Lake offers a maximum depth of approximately 22m, although divers usually stay within 110 feet due to limited visibility and cooler water temperatures. With a visibility range of around 2m, it is essential to be prepared and ensure your diving skills are suitable for these conditions. Whether you are a beginner, advanced, or expert diver, you can find a suitable dive experience in this remarkable underwater landscape.
