About Shadow Lake

The primary purpose of Shadow Lake is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Jim Bowers (private). It impounds the Tributary To S. Canadian River near Moore.

The dam stands 14 feet tall and stretches 751 feet across, creates a reservoir covering 17 acres, has a maximum storage capacity of 56 acre-feet, and collects water from a drainage area of 230 square miles. Completed in 1930, 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 02/24/2021.
