The Tombigbee River: Free-Flowing Water Below the Last Lock on the Tenn-Tom

From Coffeeville Lock & Dam to Jackson, Alabama, the engineered Tenn-Tom Waterway ends and the Tombigbee runs free to the Gulf — with catfish as the standout fishery.

Written by Atlas Editorial · Last updated

ADCNR states it plainly: "From Coffeeville Lake to Jackson, Alabama, the Tombigbee River is free flowing." Coffeeville Lock & Dam, at river mile 117, is the last lock and dam before the Gulf — everything below it is unimpounded, a sharp contrast to the fully engineered, 234-mile channelized Tenn-Tom Waterway upstream with its 10 locks. Catfish are the standout fishery on this free-flowing stretch.
