Rock Creek Dam

About Rock Creek Dam

The primary purpose of Rock Creek Dam is fish and wildlife pond. The dam creates habitat for fish and wildlife, supporting local ecosystems and potentially serving conservation goals. The dam is owned by Doi Blm (federal). It impounds the Rock Creek near Hwy 95.

The dam stands 17 feet tall and stretches 440 feet across, creates a reservoir covering 310 acres, has a maximum storage capacity of 3,600 acre-feet, and collects water from a drainage area of 28 square miles. Completed in 1939, 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 04/03/2020.
