About Altus Dam

The primary purpose of Altus 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 North Fork Red River near Blair.

The dam stands 110 feet tall and stretches 1,104 feet across, creates a reservoir covering 7,170 acres, has a maximum storage capacity of 162,025 acre-feet, and collects water from a drainage area of 2,076 square miles. Completed in 1944, the structure is well-established, with more than 75 years of service.

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 07/14/2020.

At 110 feet, this dam is taller than 98% of all dams in the United States.
