About Scs-upper Red Rock Creek Site-30

The primary purpose of Scs-upper Red Rock Creek Site-30 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 Garfield Co Cons Dist (state). It impounds the Tr-red Rock Creek near Red Rock.

The dam stands 22 feet tall and stretches 1,700 feet across, creates a reservoir covering 17 acres, and has a maximum storage capacity of 405 acre-feet. Completed in 1964, 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 11/29/2011. That was 14 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
