About Milford Dam
The primary purpose of Milford 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 - Kansas City District (federal). It impounds the Republican River near Junction City.
The dam stands 147 feet tall and stretches 6,300 feet across, creates a reservoir covering 15,708 acres, has a maximum storage capacity of 1,145,000 acre-feet, and collects water from a drainage area of 24,882 square miles. Completed in 1966, 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 07/19/2021.
