Tom Bevill Lock and Dam, Lock and dam system on Tennessee-Tombigbee Waterway in Pickens County, United States.

Tom Bevill Lock and Dam is a lock and dam system on the Tennessee-Tombigbee Waterway that creates Aliceville Lake and controls water flow between two river networks. The facility allows boats to move safely between different water levels while managing the flow throughout the connected waterway system.

The structure was first named Aliceville Lock and Dam, and also carried the name Memphis Lock and Dam, before being renamed for Tom Bevill, an Alabama congressman and proponent of the Tennessee-Tombigbee Waterway. It is one of four lock and dam structures on the waterway that generally lie along the original course of the Tombigbee River, near Aliceville, Alabama.

The structure carries the name of Tom Bevill, an Alabama congressman who backed the Tennessee-Tombigbee Waterway project. It was earlier called Aliceville Lock and Dam and also Memphis Lock and Dam, after the nearby town and the original river landing. The lock lies near Aliceville in Pickens County.

You can view the lock system from several vantage points to see how vessels pass through the structure. The best time to visit is during daylight hours when boat traffic is active through the lock.

The 41 metres in the sources is the elevation of the ground at the dam site above sea level, not the height of the structure. The lock and dam stands beside Gavin Lake, about 15.5 km from Aliceville, in Pickens County.
