About Boca Negra Detention Dam

The primary purpose of Boca Negra Detention 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 Albuquerque Metro Arroyo Flood Control Authority (local government). It impounds the Boca Negra Arroyo near Albuquerque.

The dam stands 26 feet tall and stretches 3,560 feet across, creates a reservoir covering 12 acres, has a maximum storage capacity of 241 acre-feet, and collects water from a drainage area of 14 square miles. Completed in 2014, the structure is relatively new.

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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 01/14/2021.
