About Roberts, Hunter Lake Dam
The primary purpose of Roberts, Hunter Lake 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 Roberts Hunter (private). It impounds the Gribble Br Of Clear Fork near Boonville.
The dam stands 27 feet tall and stretches 424 feet across, creates a reservoir covering 4 acres, has a maximum storage capacity of 75 acre-feet, and collects water from a drainage area of 150 square miles. Completed in 1972, the structure is well into its service life at over 50 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. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream.
