The Kansas River (known locally as 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.

The Kansas River Inventory is the first comprehensive, publicly available inventory of the river.

The Kansas River Inventory is a joint project of Friends of the Kaw, the Kansas Alliance for Wetlands and Streams and Kansas State University. We would like to thank the Kingsbury Family Foundation, the Johnson County Stormwater Program, an EPA Environmental Justice Small Grant and Patagonia for the funding that has made this possible.
