About Scs-upper Black Bear Creek Site-75
The primary purpose of Scs-upper Black Bear Creek Site-75 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 Noble Co Cons Dist (state). It impounds the Tr-black Bear Creek near Morrison.
The dam stands 25 feet tall and stretches 1,780 feet across, creates a reservoir covering 14 acres, and has a maximum storage capacity of 363 acre-feet. Completed in 1969, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 07/07/2011. That was 14 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
