About Apache Brazito Mesquite Dam No. 3
The primary purpose of Apache Brazito Mesquite Dam No. 3 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 Elephant Butte Irrigation District (local government). It impounds the Mossman Arroyo near Mesquite.
The dam stands 51 feet tall and stretches 1,925 feet across, creates a reservoir covering 10 acres, has a maximum storage capacity of 925 acre-feet, and collects water from a drainage area of 8 square miles. Completed in 1964, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 12/17/2019.
At 51 feet, this dam is taller than 93% of dams nationwide.
