Thurlow
Thurlow is a gravity dam located in Elmore County, Alabama, built in 1930. It carries a High hazard potential classification and has a satisfactory condition assessment.
About Thurlow
The primary purpose of Thurlow 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 Alabama Power Company (public utility). It impounds the Tallapoosa River near Tallassee.
The dam stands 62 feet tall and stretches 1,926 feet across, creates a reservoir covering 574 acres, has a maximum storage capacity of 18,250 acre-feet, and collects water from a drainage area of 3,300 square miles. Completed in 1930, 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. 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 06/01/2022.
At 62 feet, this dam is taller than 95% of all dams in the United States.
