Apalachia Dam is a hydroelectric dam on the Hiwassee River in Cherokee County, in the U.S. state of North Carolina. The dam is the lowermost of three dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the early 1940s to provide emergency power for aluminum production during World War II. While the dam is in North Carolina, an 8.3-mile (13.4 km) underground conduit carries water from the dam's reservoir to the powerhouse located 12 miles (19 km) downstream across the state line in Polk County, Tennessee. The dam and associated infrastructure were listed on the National Register of Historic Places in 2017. Apalachia Dam is classified by the U.S. Army Corps of Engineers as a high-hazard dam, meaning a dam failure may pose a deadly threat to nearby residents. The dam's condition is not made available to the public due to security concerns.
