The Neosho River is a tributary of the Arkansas River in eastern Kansas and northeastern Oklahoma in the United States. Its tributaries also drain portions of Missouri and Arkansas. The river is about {{convert|463|mi}} long.U.S. Geological Survey. National Hydrography Dataset high-resolution flowline data. [http://viewer.nationalmap.gov/viewer/ The National Map], accessed May 31, 2011 Via the Arkansas, it is part of the Mississippi River watershed. Its name is an Osage word meaning "clear water."[http://muskogeephoenix.com/okcentennial/x2128964679/How-places-got-their-names Muskogee Phoenix.

Course

The Neosho's headwaters are in Morris County, Kansas, and it flows southeast through Kansas. In Ottawa County, Oklahoma, the river turns south-southwest for the remainder of its course through Oklahoma. It meets the Arkansas River near the city of Muskogee, about a mile downstream of the confluence of the Arkansas River and the Verdigris River. The area of convergence of the three rivers Arkansas, Verdigris and Neosho is called "Three Forks."

In Oklahoma the Neosho ends at its confluence with Spring River at the Twin Bridges Area at Grand Lake State Park. From that point on it is called the Grand River. The Grand River flows south to the Grand Lake.

Dams

The Neosho has been dammed at several points along its course, in most cases by the U.S. Army Corps of Engineers. In Kansas, a dam upstream of Council Grove forms Council Grove Lake, and a dam near New Strawn forms John Redmond Reservoir. There are also 12 dams in between John Redmond and the Kansas border, including lowhead dams at Burlington, Neosho Falls, Ottawa, Iola, Humboldt, two near Chanute and Erie. It was also dammed to provide water for the city of Parsons, and is also dammed at the former Kansas Gas & Electric Power Plant at Strauss, as well as at Oswego and Chetopa.{{Cite web|url=http://ks.water.usgs.gov/pubs/reports/wrir.99-4147.html|title = Kansas Water Science Center | U.S. Geological Survey}} In Oklahoma, Pensacola Dam at Langley forms the Neosho's largest reservoir, the Grand Lake o' the Cherokees. Robert S. Kerr Dam near Locust Grove forms Lake Hudson, (also known as Markham Ferry Reservoir), and a dam upstream of Fort Gibson forms Fort Gibson Lake.

Tributaries

In Kansas, the Neosho is joined by the Cottonwood River in Lyon County. In Oklahoma, it is joined by the Spring River in Ottawa County and the Elk River in Delaware County.
