Kanawha River

Water type: River
Continent: North America
Climate: Continental

The Kanawha River is a tributary of the Ohio River, approximately 97 mi (156 km) long, in the U.S. state of West Virginia. The largest inland waterway in West Virginia, its watershed has been a significant industrial region of the state since early in the 19th century.

It is formed at the town of Gauley Bridge in northwestern Fayette County, approximately 35 mi (56 km) SE of Charleston, by the confluence of the New and Gauley rivers 2 mi upstream from Kanawha Falls. The waterfall is 24 ft high and has been a barrier to fish movement for more than 1 million years.

The river flows generally northwest, in a winding course on the unglaciated Allegheny Plateau, through Fayette, Kanawha, Putnam, and Mason counties, past the cities of Charleston and St. Albans, and numerous smaller communities.

It joins the Ohio at Point Pleasant.

An environmental overview and summary of natural and human factors affecting water quality in the watershed was published in 2000.
