This earth dam, completed in 1968, serves the primary purpose of flood risk reduction along TR-Sandy Creek. With a height of 27 feet and a length of 1440 feet, it has a storage capacity of 409 acre-feet and a normal storage of 59 acre-feet.
Managed by the Oklahoma Water Resources Board, this dam is regulated and inspected by the state, with a low hazard potential and a very high risk assessment rating. The controlled spillway and valve outlet gate are key features of this structure, ensuring efficient water management during peak discharges. Despite not having a current condition assessment, the SCS-Wildhorse Creek Site-117 remains a critical asset in safeguarding the surrounding areas from potential flooding events, highlighting the importance of proper water resource management in the face of climate variability.
