MUSKINGUM RIVER

river formed by the confluence of the Tuscarawas and Walhonding rivers at Coshocton, east-central Ohio, U.S. It flows about 115 miles (185 km) south past Zanesville and McConnelsville to the Ohio River at Marietta. Licking River, which joins the Muskingum at Zanesville, is the chief tributary. A series of locks, dams, and short canalsmost of them built between 1935 and 1941control flooding and make the river navigable. The name is of Algonquin Indian origin and probably means by the river.
