Ketch Lake

About Ketch Lake

The primary purpose of Ketch Lake is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Fort Sill (federal). It impounds the Blue Beaver Creek near Cache.

The dam stands 33 feet tall and stretches 95 feet across, creates a reservoir covering 19 acres, has a maximum storage capacity of 170 acre-feet, and collects water from a drainage area of 7 square miles. Completed in 1940, the structure is well-established, with more than 75 years of service.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. 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 10/24/2019.

At 33 feet, this dam is taller than 78% of dams nationwide.
