Completed in 1967, this dam stands at a height of 28 feet and spans 900 feet in length, providing a storage capacity of 145 acre-feet. The dam is located on TR-Garrison Creek and is under the jurisdiction of the Oklahoma Water Resources Board (OWRB).
Despite its low hazard potential, the SCS-Wildhorse Creek Site-073 poses a very high risk due to its age and lack of recent condition assessments. The dam features a controlled spillway and a single valve outlet gate for water release. While it has not been inspected since January 1980, the dam is subject to state permitting, inspection, and enforcement to ensure its structural integrity and compliance with regulatory standards. Its risk management measures and emergency action plan status are currently unknown.
For water resource and climate enthusiasts, the SCS-Wildhorse Creek Site-073 serves as an important flood control structure in Oklahoma, contributing to watershed management and protection of downstream communities. As a designated state-regulated dam, it highlights the ongoing efforts to mitigate flood risks and ensure the safety of water infrastructure systems. Monitoring and maintenance of this dam are crucial to safeguarding the surrounding environment and preserving water resources for future generations.
