About Pawnee Dam
The primary purpose of Pawnee 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 - Omaha District (federal). It impounds the North Branch Middle Creek near Emerald.
The dam stands 71 feet tall and stretches 5,000 feet across, creates a reservoir covering 737 acres, has a maximum storage capacity of 38,300 acre-feet, and collects water from a drainage area of 36 square miles. Completed in 1965, 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 05/07/2024.
At 71 feet, this dam is taller than 96% of all dams in the United States.
