Background and construction

In 1940, with World War II raging across Europe, the United States government saw an urgent need to strengthen its military and defense infrastructure. This required a massive expansion of aluminum production facilities, many of which were located in the Tennessee Valley. To provide the necessary electricity, the Tennessee Valley Authority submitted a proposal for the construction of a new dam on the Holston River (the site— known as the "Mossy Creek site"— had already been selected and preliminary plans had been drawn up), the construction of a new coal plant (Watts Bar Fossil Plant, which operated 1942-1982) and for the expansion of the generating capacity of the existing Wilson and Pickwick Landing

The Cherokee project required the purchase of 45158 acres (18,274.8 ha) of land, nearly 6000 acres (2,428.1 ha) of which were wooded and required clearing. The project also required the relocation of 875 families, 51 cemeteries, and a historical tavern at Bean Station

 had to be modified, and 99 miles (159.3 km) of roadway had to be redirected. Fourteen new bridges were constructed and five existing bridges were raised above reservoir operating levels. Three earthen saddle dams, with a combined length of 1770 feet (539.5 m), were constructed to fill gaps in the ridge immediately south of the main dam. As Congress eliminated a number bureaucratic obstacles regarding delivery of materials, construction proceeded at a smooth and rapid pace. On December 5, 1941, construction was completed, the gates were closed, and the reservoir began to fill. Power generation began on April 16, 1942, less than two years after the dam was first proposed.

Operation and output

Cherokee Dam is a gravity-type concrete spillway dam consisting of nine crest gates and eight sluice gates (the latter allowing reservoir control when water level is low). The combined capacity of the dam's four hydroelectric generators is 135,200 kilowatts. Cherokee Reservoir has a flood-storage capacity of 749406 acre.ft. The reservoir operates up to an elevation of 1075 feet (327.7 m), and varies by 27 feet (8.2 m) in a typical year. The dam lacks navigational locks, although its design allows them to be added if the necessity for them should arise.

While Cherokee's primary purpose is hydroelectric power production, like other TVA dams it also helps control flooding, which was rampant in the Tennessee Valley before the 1930s. Numerous recreational areas exist along Cherokee Reservoir, including Panther Creek State Park
