About Scs-upper Washita Creek Site-057
The primary purpose of Scs-upper Washita Creek Site-057 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 Upper Washita Cons Dist (state). It impounds the Croton Creek near Cheyenne.
The dam stands 59 feet tall and stretches 1,427 feet across, creates a reservoir covering 99 acres, and has a maximum storage capacity of 4,003 acre-feet. Completed in 1972, 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 01/11/2012. That was 14 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 59 feet, this dam is taller than 95% of all dams in the United States.
