Black Warrior River
The Black Warrior River is a 178 mi (286 km) long tributary of the Tombigbee River. With its upper watershed encompassing a forested area of high bluffs at the extreme southern end of the Appalachian Mountains and its western edge the suburbs of Birmingham, the Black Warrior River drains an area of 6,275 sq mi (16,250 km²) in west central Alabama. In its lower reaches, the Black Warrior River flows across the forests of the Coastal Plain. The main stem of the Black Warrior River is now impounded along nearly its entire course in a chain of narrow reservoirs constructed for hydroelectricity, drinking water, and navigation.
