Calderwood Dam, Hydroelectric arch dam in Monroe County, Tennessee, United States.
The concrete structure rises 232 feet high and stretches 916 feet across the Little Tennessee River with 24 arched-crest spillway gates.
The Aluminum Company of America completed the dam in 1930 to supply electricity for aluminum smelting operations before the Tennessee Valley Authority took control of the watershed.
The dam earned recognition on the National Register of Historic Places in 1989, with its substructures added to the listing in subsequent expansions.
Three Westinghouse generators and Francis turbines in the powerhouse, located 1.2 miles downstream, produce a combined capacity of 140.4 megawatts of electrical power.
The dam's powerhouse connects through a 1.2-mile-long tunnel system carved through the mountain, channeling water from the reservoir to generate electricity.
