About Scs-long Branch Creek Site-01
The primary purpose of Scs-long Branch Creek Site-01 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 Long Branch Cr near Morrison.
The dam stands 45 feet tall and stretches 1,920 feet across, creates a reservoir covering 44 acres, and has a maximum storage capacity of 1,695 acre-feet. Completed in 1976, the structure is 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 11/09/1999. That was 26 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 45 feet, this dam is taller than 91% of dams nationwide.
