About Scs-cherokee Sandy Site-08c

The primary purpose of Scs-cherokee Sandy Site-08c 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 Garvin Co Cons Dist (state). It impounds the Willow Sandy Creek near Wynnewood.

The dam stands 29 feet tall and stretches 1,120 feet across, creates a reservoir covering 16 acres, has a maximum storage capacity of 406 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1963, the structure is well into its service life at over 50 years old.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 06/09/2011. That was over 14 years ago.
