Great Falls

Great Falls is one of seven dams acquired by TVA from private companies, and it’s the only TVA dam located outside the Tennessee River watershed. It has two generating units with a net dependable capacity of 36 megawatts. It is located about 75 miles southeast of Nashville on the Caney Fork River.
