About Marthasville Mv-5 Dam

The primary purpose of Marthasville Mv-5 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 Marthasville (local government). It impounds the Trib To Tuque Creek near Marthasville.

The dam stands 36 feet tall and stretches 1,000 feet across, creates a reservoir covering 18 acres, has a maximum storage capacity of 414 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 2004, the structure is relatively new.

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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 02/08/2023.

At 36 feet, this dam is taller than 83% of dams nationwide.
