The dam stands 25 feet tall and stretches 900 feet across, creates a reservoir covering 240 acres, has a maximum storage capacity of 2,500 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1913, 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam.
