About Vatterot Dam
The primary purpose of Vatterot Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Glen Vatterot (private). It impounds the Tr-charrette Creek near Marthasville.
The dam stands 30 feet tall, creates a reservoir covering 10 acres, has a maximum storage capacity of 160 acre-feet, and collects water from a drainage area of 49 square miles. Completed in 1960, 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.
