The Tuscarawas River is a principal tributary of the Muskingum River, 129.9 miles (209 km) long, in northeastern Ohio in the United States. Via the Muskingum and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of 2,590 square miles (6,700 km2) on glaciated and unglaciated portions of the Allegheny Plateau.
The river rises southwest of Hartville in northern Stark County, and initially flows westward, through Uniontown into southern Summit County, where it passes through the Portage Lakes area south of Akron, and Barberton. From Barberton the Tuscarawas flows generally south through Stark and Tuscarawas counties; the communities of Clinton, Canal Fulton, Massillon, Navarre, Bolivar, Zoar, Dover, and New Philadelphia were developed along its banks. South of New Philadelphia, the river turns southwest and west, flowing past Tuscarawas, Gnadenhutten, Port Washington, and Newcomerstown, sites of former Lenape people villages at the time of the American Revolutionary War, into Coshocton County, where it joins the Walhonding River at the city of Coshocton (a former major Lenape site) to form the Muskingum River.
From Barberton downstream, the Ohio and Erie Canal was constructed parallel to the river in 1828-30 to provide for improved transportation of products and passengers. Usage began declining in the 1850s, and the canal was damaged beyond repair by flooding in 1913. Portions of the canal's towpath route are maintained as a hiking and bicycling trail.
According to the Geographic Names Information System, the Tuscarawas River has also been known historically by the names Little Muskingum River, Mashongam River, Tuscarawa River, and Tuskarawas Creek, all derived from Native American terms.
The Tuscarawas River collects Chippewa Creek in Summit County near Clinton, and Sandy Creek in Stark County near Bolivar. In Tuscarawas County, it collects Conotton Creek southeast of Zoar; Sugar Creek at Dover; and Stillwater Creek north of Tuscarawas. Nimishillen Creek, a tributary of Sandy Creek, drains the city of Canton.
At the United States Geological Survey's stream gauge in Newcomerstown, the annual mean flow of the river between 1922 and 2005 was 2,591 ft³/s (73 m³/s). The highest recorded flow during the period was 46,800 ft³/s (1,325 m³/s) on January 26, 1937. The lowest recorded flow was 216 ft³/s (6 m³/s) on August 15, 1944.
At an upstream gauge in Massillon, the annual mean flow of the river between 1938 and 2005 was 466 ft³/s (13 m³/s). The highest recorded flow during the period was 10,700 ft³/s (303 m³/s) on July 5, 1969. The lowest recorded flow was 45 ft³/s (1.3 m³/s) on September 20, 1999.
