About Leesville Dam
The primary purpose of Leesville Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Usace - Huntington District (federal). It impounds the Mcguire Creek near Sherrodville.
The dam stands 74 feet tall and stretches 1,695 feet across, creates a reservoir covering 1,000 acres, has a maximum storage capacity of 37,400 acre-feet, and collects water from a drainage area of 48 square miles. Completed in 1937, 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 04/27/2023.
At 74 feet, this dam is taller than 97% of all dams in the United States.
