About Bosley Wash Detention Basin
The primary purpose of Bosley Wash Detention Basin 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 Gudorf, Carrie (local government).
The dam stands 26 feet tall and stretches 2,375 feet across, creates a reservoir covering 20 acres, has a maximum storage capacity of 190 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 2019, the structure is relatively new.
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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 03/28/2022.
