About International Airport Dam
The primary purpose of International Airport 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 City Of Kansas City Mo (local government). It impounds the Tr Todd Creek near Platte City.
The dam stands 45 feet tall and stretches 950 feet across, creates a reservoir covering 65 acres, has a maximum storage capacity of 1,670 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1971, 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 08/23/2022.
