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), a subsidiary of Aluminum Company of America (now Alcoa), in order to generate electricity to smelt aluminum in Alcoa, Tennessee. The Cheoah project began in 1916 as a construction camp at the Narrows, where the Little Tennessee River flowed through a narrow gorge, and it was completed in 1919. Cheoah Dam created the long, narrow Cheoah Reservoir, which covers 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 that of Calderwood and Chilhowee, is primarily dependent on releases from TVA's Fontana Dam, the primary flow control facility for the lower Little Tennessee River. Tapoco operated the Cheoah Development until 2012, when it was sold to Brookfield Renewable Energy Partners, forming Brookfield Smoky Mountain Hydropower.When completed in 1919, 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. The dam and associated structures were listed on the National Register of Historic Places in 2004.The dam was used as a filming location for the 1993 movie The Fugitive, starring Harrison Ford.

Santeetlah Dam
Santeetlah Dam

Santeetlah Dam is a hydroelectric development on the Cheoah River (river mile 9) in Graham County, North Carolina. The dam together with a pipeline/tunnel facility, and a powerhouse form the Santeetlah Development. The Santeetlah powerhouse is located on the left bank of the Cheoah Reservoir portion of the Little Tennessee River five miles (8 km) upstream of the Cheoah Dam. The Santeetlah Project, which began in 1925, was completed in 1928 by the Tallassee Power Company (now Tapoco). The Santeetlah Dam forms the Santeetlah Reservoir, which covers approximately 2,881 acres (1,166 ha), normal full pool area, with a drainage area of 176 square miles (460 km2) and stretches to Robbinsville, North Carolina. The elevation of Santeetlah Reservoir is 1,940.9 feet (591.6 m) according to the USGS. The dam is 212 feet (65 m) high and 1,054 feet (321 m) long, and was one of the first structures built using vibratory damping to control concrete quality. It has two spillways with a capacity of 50,000 cfs. It is topped by concrete gatehouse which controls water flows into the five mile tunnel running to the Little Tennessee. The project's major elements were listed on the National Register of Historic Places in 2004. The Santeetlah and Cheoah developments have practically flooded the Cheoah River. Water from Santeetlah is piped to the Rhymer's Ferry generating facility on Cheoah Lake, with any water flowing below the dam coming from downstream tributaries or reservoir overflow. The facility is owned and operated by Tapoco. The Tennessee Valley Authority (TVA) maintains limited control over lake levels, as the piped output from Lake Santeetlah flows into Topoco's Santeethlah Power House at Rhymer's Ferry upstream from Cheoah Dam and just below Fontana Dam. Overflow travels to the Cheoah River just below the Cheoah Dam.
