About Keystone Dam - Cleveland Levee

The primary purpose of Keystone Dam - Cleveland Levee is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by USACE - Tulsa District (federal). It impounds the Arkansas River near Sand Springs.

The dam stands 34 feet tall and stretches 12,915 feet across, creates a reservoir covering 22,420 acres, has a maximum storage capacity of 1,672,613 acre-feet, and collects water from a drainage area of 74,506 square miles. Completed in 1964, the structure is well into its service life at over 50 years old.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 02/09/2022.
