About Morgan Falls

The primary purpose of Morgan Falls 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 Georgia Power Company (public utility). It impounds the Chattahoochee near Sandy Springs.

The dam stands 65 feet tall and stretches 895 feet across, creates a reservoir covering 750 acres, has a maximum storage capacity of 3,150 acre-feet, and collects water from a drainage area of 1,340 square miles. Completed in 1903, 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 08/03/2022.

At 65 feet, this dam is taller than 96% of all dams in the United States.
