About Scs-finn Creek Site-025
The primary purpose of Scs-finn Creek Site-025 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 Turkey Creek near Maysville.
The dam stands 39 feet tall and stretches 1,000 feet across, creates a reservoir covering 22 acres, and has a maximum storage capacity of 623 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 10/03/2011. That was 14 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 39 feet, this dam is taller than 86% of dams nationwide.
