Name That Waterway

The words we use for rivers and streams change with their geography

Is that a run, a kill or a fork? Or is it actually just a regular old stream? When it comes to naming waterways, it all seems to depend on your geography.

This map, created by designer Derek Watkins, color-codes the waterways of the U.S. by names they’re given. As Watkins explains, these names have their own name: toponyms, which are general descriptions of geographic features. The degree of geographical concentration of certain name types is pretty striking. Brooks tend to stay in New England, and bayous are primarily in the Louisiana-Mississippi area. Cañadas, rios and arroyos are concentrated in the Southwest. Branches seem to have the widest territory, covering much of the southeastern corner of the country.
