The Colorado River is one of the longest rivers in the Western United States. It begins in the Rocky Mountains of Colorado and flows southwestward until it reaches Mexico where it becomes a small stream or dry riverbed. The Colorado River forms the border between southeastern Nevada and northwestern Arizona. In Nevada, Hoover Dam and Davis Dam control the flow of the river and create two reservoirs, Lake Mead and Lake Mohave. Hoover Dam and Davis Dam both generate hydroelectric power for Nevada and neighboring states.
Use of water from the Colorado River is carefully controlled by the Colorado River Compact, a 1922 agreement which specifies the allocation of water rights between Colorado, Utah, Wyoming, New Mexico, Arizona, California, and Nevada. In addition to the Colorado River Compact, several other laws, contracts, and guidelines define the "Law of the River."
The Colorado River Basin (State of Nevada region 13) covers just over 2,500 square miles in southern Nevada and includes the following hydrographic areas: Dry Valley, Rose Valley, Eagle Valley, Spring Valley, Patterson Valley, Panaca Valley, Clover Valley, Lower Meadow Valley Wash, Kane Springs Valley, White River Valley, Pahroc Valley, Pahranagat Valley, Coyote Springs Valley, Three Lakes Valley, Las Vegas Valley, Colorado River Valley, Piute Valley, Black Mountains Area, Garnet Valley, Hidden Valley, California Wash, Muddy River Springs Area, Lower Moapa Valley, Tule Desert, Virgin River Valley, Gold Butte Area, and Greasewood Area.
The Muddy River and Virgin River also are part of the Colorado River Basin.
USGS Nevada Water Science Center maintains several streamflow gages on the Colorado River.
