Ladera Dam No. 15

About Ladera Dam No. 15

The primary purpose of Ladera Dam No. 15 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 Ladera Arroyo near Albuquerque.

The dam stands 16 feet tall and stretches 8,000 feet across, creates a reservoir covering 272 acres, has a maximum storage capacity of 1,128 acre-feet, and collects water from a drainage area of 21 square miles. Completed in 1976, the structure is 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 11/20/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
