The Cheoah Dam is a hydroelectric dam 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. [2]

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. [3]

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. [4] The dam and associated structures were listed on the National Register of Historic Places in 2004. [1]

The dam was used as a filming location for the 1993 movie The Fugitive , starring Harrison Ford and Tommy Lee Jones. [5]

<span class="mw-page-title-main">Calderwood, Tennessee</span> United States historic place

Calderwood was a community once located along the Little Tennessee River in Blount County, Tennessee, United States. Established in 1912 as a base for the Aluminum Company of America's Little Tennessee Valley hydroelectric development operations, the community continued to house construction personnel and dam maintenance personnel for nearby Calderwood Dam until the 1960s. Although the community's houses were razed after its abandonment, three buildings located in the community— the Calderwood Dam service building, the Calderwood School, and a Quonset hut used as a theater— were included in a supplementary listing for Calderwood Dam on the National Register of Historic Places in 2004.
