About Scs-long Branch Creek Site-09
The primary purpose of Scs-long Branch Creek Site-09 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 Payne Co Cons Dist (state). It impounds the Tr-long Branch Creek near Morrison.
The dam stands 24 feet tall and stretches 1,080 feet across, creates a reservoir covering 18 acres, and has a maximum storage capacity of 250 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 03/30/2002. That was 24 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
