About Scs-finn Creek Site-003a
The primary purpose of Scs-finn Creek Site-003a 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 Mcclain Co Cons Dist (state). It impounds the Tr-finn Creek near Maysville.
The dam stands 21 feet tall and stretches 750 feet across, creates a reservoir covering 3 acres, and has a maximum storage capacity of 96 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. An emergency action plan is in place for this dam. The most recent inspection on record was 11/14/2011. That was 14 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
