About Dequeen Dam
The primary purpose of Dequeen 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 - Little Rock District (federal). It impounds the Rolling Fork near Dequeen.
The dam stands 160 feet tall and stretches 2,360 feet across, creates a reservoir covering 1,700 acres, has a maximum storage capacity of 370,600 acre-feet, and collects water from a drainage area of 169 square miles. Completed in 1977, the structure is 49 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.
