About Cave Gulch Dam
The primary purpose of Cave Gulch Dam is debris control. The dam is designed to catch sediment, rocks, and debris carried by flowing water — particularly important in areas prone to mudslides or heavy erosion. The dam is owned by Doi Blm (federal). It impounds the Cave Gulch.
The dam stands 25 feet tall and stretches 713 feet across, creates a reservoir covering 51 acres, has a maximum storage capacity of 363 acre-feet, and collects water from a drainage area of 52 square miles. Completed in 1964, 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. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. The most recent inspection on record was 07/21/2017.
