John C. Stennis Lock and Dam

John C. Stennis Lock and Dam is a water control structure on the Tennessee-Tombigbee Waterway that manages water levels and allows large cargo vessels to pass through. The facility creates Columbus Lake, which stretches for many miles upstream and serves as a crucial point for navigation.

The facility was completed in the 1980s and named after influential Mississippi Senator John C. Stennis. The project was part of a federal effort to improve water transportation routes throughout the southern United States.

The lock and dam complex serves as an educational destination where students learn about water management systems and engineering principles through organized field trips.

The complex has several areas where visitors can view the structure and surrounding waterways. Fishing and boating are available year-round on the created lake, with different opportunities depending on the season.

The facility maintains specific water levels while allowing commercial vessels to navigate between the Tennessee River system and the Gulf of Mexico.
