Managed by the Oklahoma Water Resources Board (OWRB), Mccoy Denny No 1 has a low hazard potential and is classified as very high risk due to its location and purpose.

Emergency action plans and risk management measures are not reported, highlighting a potential area for improvement in ensuring the safety and security of the structure.
With a maximum storage capacity of 100 acre-feet and a normal storage of 50 acre-feet, Mccoy Denny No 1 plays a crucial role in mitigating flood risks in the region. Its controlled spillway and valve outlet gate contribute to its efficient operation, while ongoing monitoring and maintenance are essential for its continued effectiveness in protecting the surrounding areas from potential flooding events.
