This earth dam, completed in 1958, stands at a height of 23 feet and stretches 950 feet in length, with a storage capacity of 357 acre-feet. The dam is situated on TR-Wewoka Creek and is under the jurisdiction of the Oklahoma Water Resources Board, ensuring state permitting, inspection, and enforcement.
Despite its low hazard potential, SCS-Big Wewoka Creek Site-30 poses a very high risk in terms of flood management, with a controlled spillway and one outlet valve. The dam has not been inspected since January 1980 but is scheduled for inspection every 5 years. While the condition assessment is not rated, the risk assessment indicates a need for proactive risk management measures. With a surface area of 22 acres and a maximum discharge of 800 cubic feet per second, this site is a critical component in the water resource infrastructure of Hughes County, Oklahoma.
