Demopolis Lake is a sprawling 10,000-acre reservoir located at the intersection of the Black Warrior and Tombigbee Rivers in western Alabama, making it the largest impoundment along the Black Warrior-Tombigbee navigation system. This horseshoe-shaped body of water stretches 48 miles up the Warrior River and extends 53 miles up the Tennessee-Tombigbee Waterway. Created in the early 1950s by the U.S. Army Corps of Engineers, Demopolis Lake sits just west of the city of Demopolis in Marengo County and has a maximum depth of over 25 feet. The reservoir features diverse aquatic environments, with fast-flowing waters in the main channel and quieter backwater pools, providing premier fishing opportunities for various species. Nearly 8,308 acres of the lake's banks form the David K. Nelson (Demopolis) State Wildlife Management Area, focusing on wildlife conservation, particularly avifauna.
