The San Juan River is a major tributary of the Colorado River in the Southwestern United States, providing the chief drainage for the Four Corners region of Colorado, New Mexico, Utah, and Arizona. Originating as snowmelt in the San Juan Mountains of Colorado, it flows 383 miles (616 km) through the deserts of northern New Mexico and southeastern Utah to join the Colorado River at Glen Canyon.
The Dolores River is a tributary of the Colorado River, approximately 241 miles (388 km) long, in the U.S. states of Colorado and Utah. The river drains a rugged and arid region of the Colorado Plateau west of the San Juan Mountains. Its name derives from the Spanish El Rio de Nuestra Señora de Dolores, River of Our Lady of Sorrows. The river was explored and possibly named by Juan Maria Antonio Rivera during a 1765 expedition from Santa Fe.
The Dolores Project, located in the Dolores and San Juan River basins in southwestern Colorado, uses water from the Dolores River for irrigation, municipal and industrial use, recreation, fish and wildlife, and production of hydroelectric power. It also provides flood control and aids in economic redevelopment. The primary storage of Dolores River flows for all project purposes is provided by the McPhee Reservoir. Service is provided to the northwest Dove Creek area, central Montezuma Valley area, and south to the Towaoc area on the Ute Mountain Ute Indian Reservation. Irrigation water is available for 61,660 acres (249.5 km2).

The Central Utah Project is a US federal water project that was authorized for construction under the Colorado River Storage Project Act of April 11, 1956, as a participating project. In general, the Central Utah Project develops a portion of Utah's share of the yield of the Colorado River, as set out in the Colorado River Compact of 1922.
In Section 203(a) of the Central Utah Project Completion Act, the United States Congress authorized a federally authorized and funded replacement project to replace the Uinta and Upalco Units of the Central Utah Project (CUP) which were not constructed. The replacement project is the Uinta Basin Replacement Project (UBRP). The UBRP will provide: 2,500 acre-feet (3,100,000 m3) of irrigation water; 3,000 acre-feet (3,700,000 m3) of municipal and industrial water; reduced wilderness impacts; increased instream flows; and improved recreation. Design work began in 2002. Construction began in 2004 and is anticipated to be completed in 2011. The Central Utah Water Conservancy District is responsible for construction. The United States Department of the Interior oversees funding and compliance with law and environmental regulation.
The Colorado River Storage Project is a United States Bureau of Reclamation project designed to oversee the development of the upper basin of the Colorado River. 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.
Scofield Reservoir is a 2,815-acre (11.39 km2) reservoir impounded by Scofield Dam, in Carbon County, Utah.

Crawford Dam impounds water for Crawford Reservoir in Delta County, Colorado about a mile south of the town of Crawford.
Platoro Dam is a dam in Conejos County, Colorado.
Willow Creek Dam is a dam in Grand County, Colorado.
The Middle Rio Grande Project manages water in the Albuquerque Basin of New Mexico, United States. It includes major upgrades and extensions to the irrigation facilities built by the Middle Rio Grande Conservancy District and modifications to the channel of the Rio Grande to control sedimentation and flooding. The bulk of the work was done by the United States Bureau of Reclamation and the United States Army Corps of Engineers in the 1950s, but construction continued into the 1970s and maintenance is ongoing. The project is complementary to the San Juan-Chama Project, which transfers water from the San Juan River in the Colorado River Basin to the Rio Grande. Although distribution of water from the two projects is handled through separate allotments and contracts, there is some sharing of facilities including the river itself. The ecological impact on the river and the riparian zone was the subject of extended litigation after a group of environmentalists filed Rio Grande Silvery Minnow v. Bureau of Reclamation in 1999.
