The principal tributaries of the Colorado River of North America are the Gila River, the San Juan River, the Green River, and the Gunnison River.
The following is a tree demonstrating the points at which the major and minor tributaries of the Colorado River branch off from the main river and from each other.
The Little Colorado River is a tributary of the Colorado River in the U.S. state of Arizona, providing the principal drainage from the Painted Desert region. Together with its major tributary, the Puerco River, it drains an area of about 26,500 square miles (69,000 km2) in eastern Arizona and western New Mexico. Although it stretches almost 340 miles (550 km), only the headwaters and the lowermost reaches flow year-round. Between St. Johns and Cameron, most of the river is a wide, braided wash, only containing water after heavy snowmelt or flash flooding.
The Gunnison River is located in western Colorado, and it is one of the largest tributaries of the Colorado river. The 180-mile (289-km) long river flows east to west, and it has a drainage area of 7,923 square miles (20,520 km2) according to the USGS. The drainage basin of the Gunnison River collects water from different habitats, such as forests and alpine meadows, located the along Continental Divide. As the river flows westward, it carves through the San Juan Mountains. It flows into the Colorado River at Grand Junction.
Curecanti National Recreation Area(Pronounced or .) is a National Park Service unit located on the Gunnison River in western Colorado. Established in 1965, Curecanti National Recreation Area is responsible for developing and managing recreational facilities on three reservoirs, Blue Mesa Reservoir, Morrow Point Reservoir and Crystal Reservoir, constructed on the upper Gunnison River in the 1960s by the U.S. Bureau of Reclamation to better utilize the vital waters of the Colorado River and its major tributaries. 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.
The Domínguez–Escalante expedition was a Spanish journey of exploration conducted in 1776 by two Franciscan priests, Atanasio Domínguez and Silvestre Vélez de Escalante, to find an overland route from Santa Fe, New Mexico, to their Roman Catholic mission in Monterey, on the coast of modern day central California. Domínguez, Vélez de Escalante, and Bernardo de Miera y Pacheco, acting as the expedition's cartographer, traveled with ten men from Santa Fe through many unexplored portions of the American West, including present-day western Colorado, Utah, and northern Arizona. Along part of the journey, they were aided by three indigenous guides of the Timpanogos tribe.
The Colorado River Storage Project is a United States Bureau of Reclamation project designed to oversee the development of the upper Colorado River basin. The project provides hydroelectric power, flood control and water storage for participating states along the upper portion of the Colorado River and its major tributaries.
The Colorado River is a major river of the western United States and northwest Mexico in North America. Its headwaters are in the Rocky Mountains where La Poudre Pass Lake is its source. Located in north central Colorado it flows southwest through the Colorado Plateau country of western Colorado, southeastern Utah and northwestern Arizona where it flows through the Grand Canyon. It turns south near Las Vegas, Nevada, forming the Arizona–Nevada border in Lake Mead and the Arizona–California border a few miles below Davis Dam between Laughlin, Nevada and Needles, California before entering Mexico in the Colorado Desert. Most of its waters are diverted into the Imperial Valley of Southern California. In Mexico its course forms the boundary between Sonora and Baja California before entering the Gulf of California. This article describes most of the major features along the river.
