High Rock Lake Dam

About High Rock Lake Dam

The primary purpose of High Rock Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Camp High Rocks For Boys (private). It impounds the Steel Creek near Cedar Mountain.

The dam stands 37 feet tall and stretches 200 feet across, creates a reservoir covering 12 acres, and has a maximum storage capacity of 167 acre-feet. Completed in 1949, 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 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 02/08/2024.

At 37 feet, this dam is taller than 84% of dams nationwide.
