About Wheeler Dam
The primary purpose of Wheeler 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 Tennessee River near Florence.
The dam stands 175 feet tall and stretches 1,000 feet across, creates a reservoir covering 3,220 acres, has a maximum storage capacity of 228,045 acre-feet, and collects water from a drainage area of 232 square miles. Completed in 1936, the structure is well-established, with more than 75 years of service.
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 07/29/2025.
At 175 feet, this dam is taller than 99% of all dams in the United States.
