About Reservoir Dike
The primary purpose of Reservoir 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 Doi Blm (federal).
The dam stands 20 feet tall and stretches 1,050 feet across, creates a reservoir covering 11 acres, has a maximum storage capacity of 124 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1975, 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. The most recent inspection on record was 02/14/2012. That was over 14 years ago.
