Cumberland River

The Cumberland River is a major waterway of the Southern United States. The 688-mile-long (1,107 km)[2] river drains almost 18,000 square miles (47,000 km2) of southern Kentucky and north-central Tennessee. The river flows generally west from a source in the Appalachian Mountains to its confluence with the Ohio River near Paducah, Kentucky, and the mouth of the Tennessee River. Major tributaries include the Obey, Caney Fork, Stones, and Red rivers.

Although the Cumberland River basin is predominantly rural, there are also some large cities on the river, including Nashville and Clarksville, both in Tennessee. Also, the river system has been extensively developed for flood control, with major dams impounding both the main stem and many of its important tributaries.
