Kehr's Mill Trail Lower Lake Dam

About Kehr's Mill Trail Lower Lake Dam

The primary purpose of Kehr's Mill Trail Lower Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Kehr's Mill Trails Trust (private). It impounds the Tr To Caulks Creek near Clarkson Valley.

The dam stands 25 feet tall, creates a reservoir covering 12 acres, has a maximum storage capacity of 255 acre-feet, and collects water from a drainage area of 580 square miles. Completed in 1976, the structure is 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. The most recent inspection on record was 11/19/1980. That was 45 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.
