About Scs-caston Mountain Creek Site-5
The primary purpose of Scs-caston Mountain Creek Site-5 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 Leflore Co Cons Dist (state). It impounds the Little Mountain Creek near Wister.
The dam stands 63 feet tall and stretches 3,760 feet across, creates a reservoir covering 55 acres, has a maximum storage capacity of 9,245 acre-feet, and collects water from a drainage area of 14 square miles. Completed in 1974, the structure is well into its service life at over 50 years old.
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 12/23/2011. That was 14 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 63 feet, this dam is taller than 96% of all dams in the United States.
