About West Doubtful Detention Dam
The primary purpose of West Doubtful Detention Dam 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 Doi Blm (federal). It impounds the San Simon Creek near Solomon, Az.
The dam stands 32 feet tall and stretches 3,265 feet across, creates a reservoir covering 125 acres, has a maximum storage capacity of 865 acre-feet, and collects water from a drainage area of 44 square miles. Completed in 1968, the structure is well into its service life at over 50 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
