Rc&d Project Measure 83 Dam

About Rc&d Project Measure 83 Dam

The primary purpose of Rc&d Project Measure 83 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 Town Of Taos (local government). It impounds the Las Cruces Arroyo near Taos.

The dam stands 51 feet tall and stretches 2,590 feet across, has a maximum storage capacity of 337 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1967, 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 09/17/2020.

At 51 feet, this dam is taller than 93% of dams nationwide.
