Mojave River Dam - Saddle Dike 1

About Mojave River Dam - Saddle Dike 1

The primary purpose of Mojave River Dam - Saddle Dike 1 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 Usace - Los Angeles District (federal). It impounds the West Fork Mojave River near Victorville.

The dam stands 200 feet tall and stretches 2,200 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 179,400 acre-feet, and collects water from a drainage area of 215 square miles. Completed in 1971, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 06/13/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.

At 200 feet, this dam is taller than 99% of all dams in the United States.
