Lake Seven Falls Dam No 2

About Lake Seven Falls Dam No 2

The primary purpose of Lake Seven Falls Dam No 2 is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Lake Seven Falls (private). It impounds the Tr Hickory Creek near Ste Genevieve.

The dam stands 30 feet tall, creates a reservoir covering 14 acres, has a maximum storage capacity of 225 acre-feet, and collects water from a drainage area of 200 square miles. Completed in 1969, 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.

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.
