The River Atlas is a comprehensive source of information on the
Kansas River. Here you will learn about the Kansas River watershed, our
conservation priorities for the River, and information on water quality
and point source and non-point source pollution. We hope that this
information brings a better understanding about the Kansas River and the
problems it faces, and serves as a thorough resource for stakeholders,
communities, and those of us who love and care for the Kansas River.
The Kansas River (which is also called the Kaw)
begins at the confluence
of the Republican and Smoky Hill Rivers near Junction City and flows
173 miles to Kansas City, where it joins the Missouri River. The Kaw
drains almost the entire northern half of Kansas, as well as part of
Nebraska and Colorado (53,000 square miles in all), and is the longest
prairie based river in the world.
