The Cheoah Dam is a hydroelectric complex located in Graham and Swain counties, North Carolina on the Little Tennessee River between river miles 51 and 52. The Cheoah Development consists of a dam and powerhouse, the first of several constructed by the Tallassee Power Company, now Tapoco. The Cheoah project began in 1916 as a construction camp at the Narrows where the Little Tennessee River flowed through a narrow gorge, and was completed in 1919. Cheoah Dam helps form the long, narrow Cheoah Reservoir, which covers the approximately 644 acres (261 ha) of the normal full pool area and a drainage area of 1,608 square miles (4,160 km2). The elevation of Cheoah Reservoir is 1,276.8 feet (389.2 m) (USGS). A scenic highway runs the length of the reservoir.

The water inflow for Cheoah, like Calderwood and Chilhowee, is primarily dependent on releases from TVA's Fontana Dam. Fontana Dam is the primary flow control facility for the lower Little Tennessee River. Tapoco built and operates the Cheoah Development.[1]

When completed, the 225-foot (69 m) dam was the world's highest overflow dam. The turbines were the largest in the world, and the 150,000-volt transmission line had the highest voltage and the longest span for a transmission line — 5,010 feet (1,530 m) across the river below Cheoah Dam.[2]

The dam was used as a filming location for the 1993 movie The Fugitive, starring Harrison Ford.[3]
