Notes[edit]

Of the 158 named rivers that flow through the State of Colorado, all but the Green River[c] and Cimarron River[a] have their headwaters in that state.

As of February 1, 2008, the U.S. Board on Geographic Names had identified 5,564 natural streams in the State of Colorado. Of this number, 147 larger streams (2.6%) were named river and 11 (0.2%) were named rio. The vast majority of the Colorado streams (5082 or 91.3%) were named creek. Of the remaining Colorado streams, 122 (2.2%) were named arroyo, 60 (1.1%) were named wash, 44 (0.8%) were named fork, 18 (0.3%) were named branch, 17 (0.3%) were named brook, 17 (0.3%) were named run, 15 (0.3%) were named rito, 10 (0.2%) were named slough, but not a single stream was named stream. Perhaps the most unusual river name in Colorado belongs to the West Fork East Fork Williams Fork located in Garfield County.

Many streams in Colorado share a name with another stream in the same state. In addition to the Canadian River that is the largest tributary of the Arkansas River, there is also a Canadian River that is a tributary of the North Platte River. In addition to the Cimarron River that is another major tributary of the Arkansas River, there is also a Cimarron River that is a tributary of the Gunnison River. There is a Fall River that is a tributary of the Big Thompson River as well as a Fall River that is a tributary of Clear Creek.

There are 72 streams in the State of Colorado that are named Willow Creek, 71 streams named Spring Creek, 53 streams named Cottonwood Creek, 49 streams named Bear Creek, 49 streams named Beaver Creek, 48 streams named Dry Creek, 33 streams named Rock Creek, 33 streams named Sand Creek, and 32 streams named Mill Creek. The Arkansas River and the Colorado River flow through Colorado, as do a Florida River, an Idaho Creek, an Illinois River, an Indiana Creek, a Maryland Creek, a Michigan River, a Minnesota Creek, six Missouri Creeks, a Montana Creek, two New York Creeks, two Ohio Creeks, two Pennsylvania Creeks, two Tennessee Creeks, seven Texas Creeks, and a Virginia Creek.

Notes[edit]

  1. ^ a b c The headwaters of the Cimarron River are located in Union County, New Mexico, a short distance south of the Colorado border.
  2. ^ a b The Colorado River did not officially flow through the State of Colorado until July 25, 1921. Prior to that date, the origin of the Colorado River was officially the confluence of the Grand and Green rivers at 38°11′21″N 109°53′09″W / 38.1892°N 109.8857°W / 38.1892; -109.8857 (Confluence of the Green and Colorado rivers) in what is now Canyonlands National Park of Utah. In 1921, U.S. Representative Edward T. Taylor of Colorado petitioned the Congressional Committee on Interstate and Foreign Commerce to rename the Grand River as the Colorado River.[3] On July 25, 1921, President Warren G. Harding signed House Joint Resolution 32 - To change the name of the Grand River in Colorado and Utah to the Colorado River,[4] over the objections of representatives from Wyoming, Utah, and the United States Geological Survey, who noted that the Green River was longer and had a larger drainage basin, although the Grand River often contributed a greater flow of water.
  3. ^ a b The headwaters of the Green River are located in the Wind River Mountains of the State of Wyoming.
  4. ^ a b The Gunnison River Basin is the most extensive river basin exclusively within the State of Colorado.
