Lake Jocassee (/dʒəˈkæsi/, /dʒoʊˈkæsi/) is a 7,500-acre (30 km2), 300-foot (91 m) deep reservoir in northwest South Carolina. It was created in 1973 by the state in partnership with Duke Power. The lake is known for the clean and cold Appalachian mountain rivers that flow into it, keeping its waters cool and clear year-round. The Jocassee Dam, which forms the lake, is 385 feet (117 m) high and 1,750 feet (530 m) long. The lake is within Devils Fork State Park. Several waterfalls flow directly into the lake, including Laurel Fork Falls, Mill Creek Falls, Wright Fork Falls, and Moondance Falls.
