The dam stands 66 feet tall and stretches 4,470 feet across, creates a reservoir covering 2,640 acres, has a maximum storage capacity of 77,500 acre-feet, and collects water from a drainage area of 36 square miles. Completed in 1959, 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.
