Neosho River

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 460 mi (740 km) long. Via the Arkansas, it is part of the Mississippi River watershed.

In its southern portion, it is also known as the Grand River.

Course

The Neosho rises in Morris County, Kansas and initially flows southeastwardly through southeastern Kansas. In Ottawa County, Oklahoma the river turns south-southwestwardly for the remainder of its course through Oklahoma. It meets the Arkansas River near the city of Muskogee, about a mile downstream of the mouth of the Verdigris River.

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.
