Notes

Of the 158 named rivers that flow through the State of Colorado, all but the Green River [lower-alpha 3] and Cimarron River [lower-alpha 1] 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

  1. 1 2 3 The headwaters of the Cimarron River are located in Union County, New Mexico, a short distance south of the Colorado border.
  2. 1 2 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″N109°53′09″W / 38.1892°N 109.8857°W 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. 1 2 The headwaters of the Green River are located in the Wind River Mountains of the State of Wyoming.
  4. 1 2 The Gunnison River Basin is the most extensive river basin exclusively within the State of Colorado.

<span class="mw-page-title-main">San Luis Valley</span> High-altitude basin in Colorado and New Mexico in the United States

The San Luis Valley is a region in south-central Colorado with a small portion overlapping into New Mexico. The valley is approximately 122 miles (196 km) long and 74 miles (119 km) wide, extending from the Continental Divide on the northwest rim into New Mexico on the south. It contains 6 counties and portions of 3 others. It is an extensive high-elevation depositional basin of approximately 8,000 square miles (21,000 km2) with an average elevation of 7,664 feet (2,336 m) above sea level. The valley is a section of the Rio Grande Rift and is drained to the south by the Rio Grande, which rises in the San Juan Mountains to the west of the valley and flows south into New Mexico. The San Luis Valley has a cold desert climate but has substantial water resources from the Rio Grande and groundwater.

<span class="mw-page-title-main">South Platte River</span> River in Colorado and Nebraska, United States

The South Platte River is one of the two principal tributaries of the Platte River. Flowing through the U.S. states of Colorado and Nebraska, it is itself a major river of the American Midwest and the American Southwest/Mountain West. Its drainage basin includes much of the eastern flank of the Rocky Mountains in Colorado, much of the populated region known as the Colorado Front Range and Eastern Plains, and a portion of southeastern Wyoming in the vicinity of the city of Cheyenne. It joins the North Platte River in western Nebraska to form the Platte, which then flows across Nebraska to the Missouri. The river serves as the principal source of water for eastern Colorado. In its valley along the foothills in Colorado, it has permitted agriculture in an area of the Colorado Piedmont and Great Plains that is otherwise arid.

A popular destination for boating and fishing, Curecanti offers visitors two marinas, traditional and group campgrounds, hiking trails, boat launches, and boat-in campsites. The state's premiere lake trout and Kokanee salmon fisheries, Curecanti is a popular destination for boating and fishing, and is also a popular area for ice-fishing in the winter months.
