Cheyenne Bottoms, Wetland and Ramsar site in Barton County, United States.

Cheyenne Bottoms is a large wetland in western Kansas formed by five artificial water pools connected by channels fed from the Arkansas River and Wet Walnut Creek. The area spans over 40,000 acres and creates a patchwork of shallow water, marshland, and reedy vegetation that shifts with seasonal water levels.

Kansas acquired the land during the 1940s and 1950s, building dikes to form the water pools that exist today. Funding came from hunting licenses, and the project eventually transformed the area into one of North America's most important wetland refuges for migrating birds.

This place holds deep meaning for people who study and hunt waterfowl, serving as a gathering point during seasonal migrations. The site reflects a local commitment to protecting water habitats while allowing traditional hunting practices.

The site is accessible by maintained parking areas and boat ramps, with an observation tower providing elevated viewing points for wildlife watching. Plan visits during spring and fall migrations when bird populations peak, as water levels and wildlife activity vary throughout the year.

During migration season, the wetland hosts more than 350 bird species and can temporarily support over 250,000 waterfowl at once. These massive concentrations make it one of the world's most important stopping points for birds traveling between northern breeding grounds and southern wintering areas.
