Kansas River

The Kansas River, also known as the Kaw, is a river in northeastern Kansas in the United States. It is the southwestern-most part of the Missouri River drainage, which is in turn the northwestern-most portion of the extensive Mississippi River drainage. Its two names both come from the Kanza people who once inhabited the area; Kansas was one of the anglicizations of the French transcription Cansez of the original kką:ze. The city of Kansas City, Missouri, was named for the river, as was later the state of Kansas.
The river valley averages 2.6 miles in width, with the widest points being between Wamego and Rossville, where it is up to 4 miles wide, then narrowing to 1 mile or less in places below Eudora and De Soto. Much of the river's watershed is dammed for flood control, but the Kansas River is generally free-flowing and has only minor obstructions, including diversion weirs and one low-impact hydroelectric dam.
