About Hubbell Lake Detention Dam
The primary purpose of Hubbell Lake 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 Rio Grande - Tr near Albuquerque.
The dam stands 23 feet tall and stretches 4,650 feet across, creates a reservoir covering 41 acres, has a maximum storage capacity of 620 acre-feet, and collects water from a drainage area of 35 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. 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 06/25/2019.
