Via the Muskingum and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of on glaciated and unglaciated portions of the Allegheny Plateau. ==Route== 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.〔DeLorme (1991).

ISBN 0-89933-233-1.〕 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 state of Ohio Environmental Protection Agency has recommended limits on the consumption of fish taken from the river, due to contamination by mercury and PCBs. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tuscarawas River」の詳細全文を読む スポンサード リンク
