The dam stands 90 feet tall and stretches 26,400 feet across, creates a reservoir covering 930 acres, has a maximum storage capacity of 45,000 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2005, the structure is relatively new.

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.
