About Pomme De Terre Dam
The primary purpose of Pomme De Terre 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 Pomme De Terre River near Hermitage.
The dam stands 155 feet tall and stretches 4,630 feet across, creates a reservoir covering 7,820 acres, has a maximum storage capacity of 650,000 acre-feet, and collects water from a drainage area of 611 square miles. Completed in 1961, 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 05/28/2022.
At 155 feet, this dam is taller than 99% of all dams in the United States.
