The dam stands 11 feet tall and stretches 75 feet across, creates a reservoir covering 134 acres, has a maximum storage capacity of 1,018 acre-feet, and collects water from a drainage area of 5 square miles. Completed in 1911, the structure is over a century 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat.
