Cumberland River
The Cumberland River is a major waterway of the Southern United States. The river drains almost 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.
