Lake Norman, created between 1959 and 1964 as part of the construction of the Cowans Ford Dam by Duke Energy, is the largest man-made body of fresh water in North Carolina. Lake Norman is fed by the Catawba River, and drains into Mountain Island Lake to the south. It was named after former Duke Power president Norman Atwater Cocke. Lake Norman is sometimes referred to as the "inland sea" of North Carolina; it offers 520 miles (840 km) of shoreline and a surface area of more than 50 square miles (130 km2). Full pond at Lake Norman is 760 feet (230 m) above mean sea level.
