About Silver Lake

The primary purpose of Silver Lake is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Silver Lake Community Association (private). It impounds the Bennett Run.

The dam stands 6 feet tall and stretches 200 feet across, creates a reservoir covering 24 acres, has a maximum storage capacity of 79 acre-feet, and collects water from a drainage area of 5 square miles. Completed in 1910, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 12/09/2020.
