About Dd No 110
The primary purpose of Dd No 110 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 Middle Walnut Wjd No 60 (local government). It impounds the Foos Creek-tr near Winfield.
The dam stands 30 feet tall and stretches 850 feet across, creates a reservoir covering 18 acres, has a maximum storage capacity of 581 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1989, the structure is 37 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 10/12/2023.
