About Scs-stillwater Creek Site-33c
The primary purpose of Scs-stillwater Creek Site-33c is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Payne County Conservation District (state). It impounds the Tributary to Cimarron River near Stillwater.
The dam stands 23 feet tall and stretches 1,000 feet across, creates a reservoir covering 54 acres, has a maximum storage capacity of 422 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2005, the structure is relatively new.
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 10/12/2011. That was 15 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
