About Frd No 7
The primary purpose of Frd No 7 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 Upper Walnut Wjd No 33 (local government). It impounds the Walnut River-tr near El Dorado.
The dam stands 27 feet tall and stretches 2,300 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 684 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1981, the structure is 45 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 04/22/2022.
