About Covalt Dam
The primary purpose of Covalt 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 John Covalt (private). It impounds the Browns Creek near Broadwater.
The dam stands 18 feet tall and stretches 1,850 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 1,207 acre-feet, and collects water from a drainage area of 15 square miles. Completed in 1964, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. The most recent inspection on record was 03/17/2023.
