About Little Robber Det. Dam X
The primary purpose of Little Robber Det. Dam X 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 Little Robbers Gulch near Baggs Wyo..
The dam stands 48 feet tall and stretches 765 feet across, creates a reservoir covering 37 acres, has a maximum storage capacity of 402 acre-feet, and collects water from a drainage area of 8 square miles. Completed in 1953, the structure is well into its service life at over 50 years old.
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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 08/04/2020.
At 48 feet, this dam is taller than 92% of dams nationwide.
