About Isabella Dam

The primary purpose of Isabella 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 Usace - Sacramento District (federal). It impounds the Kern River near Bodfish.

The dam stands 185 feet tall and stretches 1,695 feet across, creates a reservoir covering 11,200 acres, has a maximum storage capacity of 1,202,000 acre-feet, and collects water from a drainage area of 2,074 square miles. Completed in 1953, 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 01/15/2026.

At 185 feet, this dam is taller than 99% of all dams in the United States.
