About Mandeville Lake Dam
The primary purpose of Mandeville Lake Dam is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by Rudy Ruechel (private). It impounds the Tr-turkey Creek near Carrolton.
The dam stands 25 feet tall, creates a reservoir covering 20 acres, has a maximum storage capacity of 268 acre-feet, and collects water from a drainage area of 472 square miles. Completed in 1932, the structure is well-established, with more than 75 years of service.
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.
