This earth dam stands at a height of 24 feet and has a length of 850 feet, providing a storage capacity of 366 acre-feet. Despite its low hazard potential, the dam has a very high risk assessment rating of 1, emphasizing the importance of regular inspections and maintenance.
The dam features a controlled spillway and a single valve outlet gate for water release. While the dam's condition assessment is currently not rated, it undergoes inspections every 5 years, with the last inspection conducted in 1980. The dam is under the jurisdiction of the Oklahoma Water Resources Board (OWRB) and is designed to withstand hydraulic pressures to protect the surrounding community of MEHAN from potential flooding events.
With its strategic location and purposeful design, SCS-Stillwater Creek Site-11 plays a crucial role in managing flood risk along the TR-STILLWATER CREEK. As a key infrastructure project in the Tulsa District, this dam serves as a testament to the collaborative efforts of state and federal agencies in safeguarding water resources and promoting climate resilience in Oklahoma.
