About Scs-cotton-coon-mission Cr Site-007
The primary purpose of Scs-cotton-coon-mission Cr Site-007 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 Caney Valley Cons Dist (state). It impounds the Brush Creek near Copan.

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 01/01/1980. That was 46 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
