Hiwassee Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina. It is one of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s to bring flood control and electricity to the region. The dam impounds the Hiwassee Lake of 6,000 acres (2,400 ha), and its tailwaters are part of Apalachia Lake. At 307 feet (94 m), Hiwassee Dam is the highest overspill dam east of the Mississippi River and is second only to Grand Coulee dam in the nation. At the time it was completed, it was the highest overspill dam in the world.
