Completed in 1968, this structure stands at a height of 18 feet with a hydraulic height of 16 feet, providing a normal storage capacity of 25 acre-feet and a maximum storage of 61 acre-feet. With a low hazard potential and a very high risk assessment rating, this dam is equipped with a controlled spillway and a single valve outlet gate for operational control.
Managed by the OWRB, this dam has not been rated for its condition assessment and lacks recent inspection data since January 1980. Despite its age, SCS-Tonkawa Creek Site-010 continues to serve its purpose effectively with no reported modifications or emergency action plan in place. With a maximum discharge capacity of 330 cubic feet per second, this structure plays a crucial role in mitigating potential flooding events in the Caddo County region of Oklahoma. Overall, this dam is a key piece of infrastructure in the state's efforts to manage water resources and adapt to changing climate conditions.
