American Cent Corp Upper Dam

About American Cent Corp Upper Dam

The primary purpose of American Cent Corp Upper Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by American Central Corp (private). It impounds the Tr Fonso Branch near Big Spring.

The dam stands 30 feet tall, creates a reservoir covering 3 acres, has a maximum storage capacity of 48 acre-feet, and collects water from a drainage area of 19 square miles.

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.

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.
