Lake Luna Dam

About Lake Luna Dam

The primary purpose of Lake Luna Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by City Of Harrisonville (local government). It impounds the Town Creek near Harrisonville.

The dam stands 17 feet tall, creates a reservoir covering 17 acres, has a maximum storage capacity of 155 acre-feet, and collects water from a drainage area of 1,310 square miles. Completed in 1920, the structure is over a century 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. The most recent inspection on record was 04/12/1979. That was 47 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

Living Downstream

If you live or work downstream of this dam, consider taking these steps: learn your local evacuation routes, check whether your county emergency management office has a dam failure inundation map, and sign up for local emergency alerts. The Missouri dam safety program can provide more specific information about emergency planning for this structure.
