Colorado Drainage Basins

This is a list of drainage basins in the U.S. State of Colorado.

Colorado encompasses the headwaters of several important rivers. The state is divided into two major hydrographic regions by the Continental Divide of the Americas. East of the Continental Divide, surface waters flow to the Gulf of Mexico, either via the Rio Grande or via one of several rivers (the South Platte River, the North Platte River, the Republican River, the Arkansas River, the Cimarron River, or the Canadian River) which eventually feed the Mississippi River along the way. West of the Continental Divide, surface waters flow via the Green River, the upper Colorado River (formerly the Grand River), or the San Juan River into the Colorado River and on to the Gulf of California.

Colorado also has three significant endorheic basins: the San Luis Closed Basin in the San Luis Valley, and the Bear Creek Basin and the White Woman Basin spanning the Colorado-Kansas border north and south of the Arkansas River.

Notes

  1. ^ 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. 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, 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.
  2. ^ The summit of Uncompahgre Peak at 14,321 feet (4365.0 m) is the highest point in the drainage basins of the Cimarron River, the Gunnison River, the former Grand River, the Colorado River, and the Gulf of California.
  3. ^ The summit of Mount Elbert at 14,440 feet (4401.2 m) is the highest point in the drainage basins of the Arkansas River and the Mississippi River.
  4. ^ The summit of Blanca Peak at 14,351 feet (4374 m) is the highest point in the drainage basin of the Rio Grande (Rio Bravo del Norte).
  5. ^ The headwaters of the Green River are located in the Wind River Mountains of the State of Wyoming.
  6. ^ The summit of Clark Peak at 12,960 feet (3950 m) is the highest point in the drainage basins of the Laramie River and the North Platte River.
  7. ^ The summit of Mount Lincoln at 14,293 feet (4356.5 m) is the highest point in the drainage basins of the South Platte River, the Platte River, and the Missouri River.
  8. ^ The headwaters of the Cimarron River are located in Union County, New Mexico, a short distance south of the Colorado border.
  9. ^ The Gunnison River Basin is the most extensive river basin exclusively within the State of Colorado.
  10. ^ The summit of Culebra Peak at 14,053 feet (4283 m) is the highest point in the drainage basin of the Purgatoire River.
  11. ^ The San Luis Closed Basin is the most extensive endorheic basin in the State of Colorado.
  12. ^ The summit of Crestone Peak at 14,300 feet (4359 m) is the highest point in the San Luis Closed Basin.
  13. ^ The summit of Hagues Peak at 13,573 feet (4137 m) is the highest point in the drainage basins of the Cache la Poudre River and the Big Thompson River.
  14. ^ The summit of West Spanish Peak at 13,631 feet (4155 m) is the highest point in the drainage basins of the Huerfano River and Apishapa River.
  15. ^ The point at which the Arikaree River flows out of the Colorado and into Kansas is the lowest point in the State of Colorado at 3317 feet (1011 m).
  16. ^ The summit of Castle Peak at 14,279 feet (4352.2 m) is the highest point in the drainage basins of the Roaring Fork River and the Taylor River.
