Mud Creek 4-j

About Mud Creek 4-j

The primary purpose of Mud Creek 4-j 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 Lower Big Blue Natural Resources District (local government). It impounds the Bloody Run near Blue Springs.

The dam stands 60 feet tall and stretches 1,585 feet across, creates a reservoir covering 149 acres, has a maximum storage capacity of 4,066 acre-feet, and collects water from a drainage area of 13 square miles. Completed in 1968, 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. The most recent inspection on record was 07/07/2022.

At 60 feet, this dam is taller than 95% of all dams in the United States.
