About Miller Lake Dam
The primary purpose of Miller Lake 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 Usaf Acc (federal). It impounds the Reeds Creek near Beale Afb.
The dam stands 26 feet tall and stretches 1,300 feet across, creates a reservoir covering 580 acres, has a maximum storage capacity of 500 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1955, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. An emergency action plan is in place for this dam. The most recent inspection on record was 07/18/2022.
