About Blue Mesa Dam

The primary purpose of Blue Mesa 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 Bureau Of Reclamation (federal). It impounds the Gunnison River near Austin.

The dam stands 390 feet tall and stretches 785 feet across, creates a reservoir covering 9,180 acres, has a maximum storage capacity of 938,469 acre-feet, and collects water from a drainage area of 3,429 square miles. Completed in 1966, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 07/18/2023.

At 390 feet, this dam is taller than 99% of all dams in the United States.
