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 463 miles (745 km) long.^[4] Via the Arkansas, it is part of the Mississippi River watershed.

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.

In Oklahoma the Neosho ends at its confluence with Spring River at Twin Bridges 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. In Oklahoma, a dam at Langley forms the Neosho's largest reservoir, the Grand Lake o' the Cherokees. A 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.
