Cheoah
Cheoah is a gravity dam located in Graham County, North Carolina, built in 1919. It carries a High hazard potential classification and has a satisfactory condition assessment.
About Cheoah
The primary purpose of Cheoah is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Brookfield Renewable Energy Group (aro) (private). It impounds the Little Tennessee near Tapoco.
The dam stands 236 feet tall and stretches 750 feet across, creates a reservoir covering 1,767 acres, has a maximum storage capacity of 42,000 acre-feet, and collects water from a drainage area of 1,608 square miles. Completed in 1919, the structure is over a century old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 07/20/2022.
At 236 feet, this dam is taller than 99% of all dams in the United States.
