The list of words for America’s watery topography is as long as the Colorado. The terms vary wildly from region to region, and culture to culture: "brooks" in New England; "sloughs" in the Pacific Northwest, and "cañadas" in the Southwest, to name a few. That diverse nomenclature is the subject of this enlightening infographic by Derek Watkins:

Watkins used data from the USGS National Hydrography Dataset to plot generic place names for rivers and creeks in color codes across a map of the United States. The key up top tells you which color goes with which name.
It doesn’t take much digging to realize that cultural factors have a huge impact on how we label the natural world. In turn, we can learn a lot about our roots just by zeroing in on geographic names. Note how much clustering you’ve got here: New York is peppered with dark blue (kills); the Gulf Coast and Louisiana have tons of lime green (bayous); and the southwest is scored with orange hues (arroyos, cañadas, and rios). These names reflect larger settlement patterns. The distribution of kills, a word that originates from Dutch, traces the colonial province of New Netherland in New York. Bayous figure prominently along French settlements in the south. And the Spanish-derived arroyos, cañadas, and rios echo the sallies of early conquistadors in modern-day New Mexico.
Not all the nomenclature is cut and dry, though. West Virginia is sliced almost perfectly in half, with runs in the north and branches in the south. A few states over, a lone patch of branches (a common term in Appalachia) dots the southwestern edge of Wisconsin. Watkins guesses it has something to do with "the diffusion of naming practice by way of branch-loving Appalachian miners during a regional lead mining boom in the early 19th century." Any armchair historians among you with other ideas? Watkins welcomes comments on his website.
