The dam stands 68 feet tall and stretches 2,080 feet across, creates a reservoir covering 668 acres, has a maximum storage capacity of 25,900 acre-feet, and collects water from a drainage area of 38 square miles. Completed in 1928, the structure is well-established, with more than 75 years of service.

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.
