Lake Norman is fed by the Catawba River, and drains into Mountain Island Lake to the south. It borders on the city of Cornelius, NC. 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. Interstate 77 and North Carolina Highway 150 cross Lake Norman at different points. Lake Norman provides electricity to the Piedmont region of the Carolinas. It powers the generators at the hydroelectric station at Cowans Ford Dam, and is used by Marshall Steam Station and McGuire Nuclear Station to cool the steam that drives their turbines. The lake supplies water to Lincoln County, Catawba County, Iredell County, Mooresville, Charlotte, and other towns in Mecklenburg County, particularly Davidson and Huntersville. Duke Power partnered with the state of North Carolina to establish Lake Norman State Park. It has also built two bank fishing areas and eight public boating access areas along the shoreline. One site is leased to Mecklenburg County and one to Iredell County. Popular game fish in Lake Norman include catfish, crappie, bluegill and yellow perch, as well as striped, largemouth, white bass along with multiple types of turtles. On December 11, 2014, Duke Energy, to repair a rusted, leaking pipe, received approval from North Carolina to dump Coal Ash (containing arsenic, lead and mercury, among other heavy metals) from the Marshall Steam Station into Lake Norman.
