About Normandy Dam
The primary purpose of Normandy Dam 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 Tva (federal). It impounds the Duck River near Shelbyville.
The dam stands 110 feet tall and stretches 2,807 feet across, creates a reservoir covering 3,000 acres, has a maximum storage capacity of 126,000 acre-feet, and collects water from a drainage area of 195 square miles. Completed in 1976, the structure is 50 years 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. An emergency action plan is in place for this dam. The most recent inspection on record was 08/20/2024.
At 110 feet, this dam is taller than 98% of all dams in the United States.
