About Elk City Dam - Rim Dike

The primary purpose of Elk City Dam - Rim Dike 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 Elk River near Independence.

The dam stands 43 feet tall and stretches 21,300 feet across, creates a reservoir covering 4,440 acres, has a maximum storage capacity of 850,405 acre-feet, and collects water from a drainage area of 634 square miles. Completed in 1966, 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 04/21/2025.
