The SCS-Wildhorse Creek Site-065, located in Garvin, Oklahoma, is a state-regulated dam managed by the Oklahoma Water Resources Board (OWRB) for flood risk reduction along the TR-Sandy Bear Creek.

Built by the USDA NRCS in 1963, this earth dam stands at a height of 30 feet with a length of 1125 feet, providing a storage capacity of 215 acre-feet for flood control purposes. The dam features a controlled spillway and a single valve outlet gate for water release.
Despite its low hazard potential, the SCS-Wildhorse Creek Site-065 has a very high risk assessment due to its age and lack of recent condition assessments. The dam is currently not rated for its structural condition, and no emergency action plan (EAP) or inundation maps have been prepared. With an inspection frequency of 5 years and the last inspection date recorded in 1980, there is a need for updated risk management measures and guidelines to ensure the safety and functionality of this critical infrastructure in the face of changing climate conditions and potential water resource challenges.
