About Crescent Wash Dam

The primary purpose of Crescent Wash 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 N/a near Crescent Junction, Utah.

The dam stands 33 feet tall and stretches 900 feet across, creates a reservoir covering 41 acres, has a maximum storage capacity of 26 acre-feet, and collects water from a drainage area of 19 square miles. Completed in 1952, 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 unsatisfactory, indicating serious safety deficiencies exist that require immediate attention or remedial action. The most recent inspection on record was 11/30/2020.

At 33 feet, this dam is taller than 78% of dams nationwide.
