About Santa Rosa Dam
The primary purpose of Santa Rosa 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 Usace - Albuquerque District (federal). It impounds the Pecos River near Santa Rosa.
The dam stands 214 feet tall and stretches 1,900 feet across, creates a reservoir covering 16,670 acres, has a maximum storage capacity of 717,000 acre-feet, and collects water from a drainage area of 2,434 square miles. Completed in 1979, the structure is 47 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 04/07/2022.
At 214 feet, this dam is taller than 99% of all dams in the United States.
