Oaks Park

About Oaks Park

The primary purpose of Oaks Park is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Ashley Valley Reservoir Company (private). It impounds the Big Brush Creek near None - Drains To Gre.

The dam stands 56 feet tall and stretches 1,108 feet across, has a maximum storage capacity of 9,080 acre-feet, and collects water from a drainage area of 11 square miles. Completed in 1938, 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 08/08/2023.

At 56 feet, this dam is taller than 94% of dams nationwide.
