About Scs-delaware Creek Site-003

The primary purpose of Scs-delaware Creek Site-003 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 Johnston Co Cons Dist (state). It impounds the Tr-sandy Creek near Wapanucka.
