The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands. Headquartered in Washington, D.C., and with oversight over 247.3 million acres (1,001,000 km2), it governs one eighth of the country's landmass.
The Reclamation Act of 1902 is a United States federal law that funded irrigation projects for the arid lands of 20 states in the American West.
The Colorado River is one of the principal rivers in the Southwestern United States and in northern Mexico. The 1,450-mile-long (2,330 km) river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora.
The Bureau of Reclamation, formerly the United States Reclamation Service, is a federal agency under the U.S. Department of the Interior, which oversees water resource management, specifically as it applies to the oversight and operation of the diversion, delivery, and storage projects that it has built throughout the western United States for irrigation, water supply, and attendant hydroelectric power generation. It is currently the U.S.'s largest wholesaler of water, bringing water to more than 31 million people, and providing one in five Western farmers with irrigation water for 10 million acres of farmland, which produce 60% of the nation's vegetables and 25% of its fruits and nuts. The Bureau is also the second largest producer of hydroelectric power in the western U.S.
The Flathead Indian Reservation, located in western Montana on the Flathead River, is home to the Bitterroot Salish, Kootenai, and Pend d'Oreilles tribes – also known as the Confederated Salish and Kootenai Tribes of the Flathead Nation. The reservation was created through the July 16, 1855, Treaty of Hellgate.
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 Desert Land Act is a United States federal law which was passed by the United States Congress on March 3, 1877, to encourage and promote the economic development of the arid and semiarid public lands within certain states of the Western states. Through the Act, United States citizens, or those declaring an intent to become a citizen, over the age of 21 may apply for a desert-land entry to irrigate and reclaim the land. This act amended the Homestead Act of 1862. Originally the act offered 640 acres (2.6 km2), although currently only 320 acres may be claimed.
The General Mining Act of 1872 is a United States federal law that authorizes and governs prospecting and mining for economic minerals, such as gold, platinum, and silver, on federal public lands. This law, approved on May 10, 1872, codified the informal system of acquiring and protecting mining claims on public land, formed by prospectors in California and Nevada from the late 1840s through the 1860s, such as during the California Gold Rush. All citizens of the United States of America 18 years or older have the right under the 1872 mining law to locate a lode or placer (gravel) mining claim on federal lands open to mineral entry. These claims may be located once a discovery of a locatable mineral is made. Locatable minerals include but are not limited to platinum, gold, silver, copper, lead, zinc, uranium and tungsten.
The General Land Office (GLO) was an independent agency of the United States government responsible for public domain lands in the United States. It was created in 1812 to take over functions previously conducted by the United States Department of the Treasury. Starting with the enactment of the Land Ordinance of 1785, which created the Public Land Survey System, the Treasury Department had already overseen the survey of the "Northwest Territory", including what is now the state of Ohio.
In the American legal system, prior appropriation water rights is the doctrine that the first person to take a quantity of water from a water source for "beneficial use" has the right to continue to use that quantity of water for that purpose. Subsequent users can take the remaining water for their own use if they do not impinge on the rights of previous users.
Federal lands are lands in the United States owned by the federal government. Pursuant to the Property Clause of the United States Constitution, Congress has the power to retain, buy, sell, and regulate federal lands, such as by limiting cattle grazing on them. These powers have been recognized in a long line of United States Supreme Court decisions.
The Taylor Grazing Act of 1934 is a United States federal law that provides for the regulation of grazing on the public lands to improve rangeland conditions and regulate their use.
The Arizona State Land Department is a department of the state government in the U.S. state of Arizona dedicated to the management of state-owned lands and property.
Navajo Dam is a dam on the San Juan River, a tributary of the Colorado River, in northwestern New Mexico in the United States. The 402-foot (123 m) high earthen dam is situated in the foothills of the San Juan Mountains about 44 miles (71 km) upstream and east of Farmington, New Mexico. It was built by the U.S. Bureau of Reclamation (Reclamation) in the 1960s to provide flood control, irrigation, domestic and industrial water supply, and storage for droughts. A small hydroelectric power plant was added in the 1980s.
Title 16 of the United States Code outlines the role of conservation in the United States Code.
Title 25 of the United States Code outlines the role of Indians in the United States Code.
Indian termination is a phrase describing United States policies relating to Native Americans from the mid-1940s to the mid-1960s. It was shaped by a series of laws and practices with the intent of assimilating Native Americans into mainstream American society. Cultural assimilation of Native Americans was not new; the belief that indigenous people should abandon their traditional lives and become what the government considers "civilized" had been the basis of policy for centuries. What was new, however, was the sense of urgency that, with or without consent, tribes must be terminated and begin to live "as Americans." To that end, Congress set about ending the special relationship between tribes and the federal government.
The Omnibus Public Land Management Act of 2009 is a land management law passed in the 111th United States Congress and signed into law by President Barack Obama on March 30, 2009. The bill designates millions of acres in the US as protected and establishes a National Landscape Conservation System. It includes funding for programs, studies and other activities by the Department of the Interior and the Department of Agriculture, and in some cases bars further geothermal leasing, oil and gas leasing, and new mining patents on certain stretches of protected land.
Water law in the United States refers to the Water resources law laws regulating water as a resource in the United States. Beyond issues common to all jurisdictions attempting to regulate water's uses, water law in the United States must contend with:
The Yuma Project is a U.S. Bureau of Reclamation project built to irrigate over 68,000 acres (280 km2) of land in Yuma County, Arizona and parts of Imperial County, California. The project is designed to exploit year-round farming conditions and water from the Colorado River. It consists of the Laguna Diversion Dam, pumping plants, a power plant, a 53-mile (85 km) system of canals, 218 miles (351 km) of lateral canals, levees and drains. The project began in 1903 and the majority of the work was completed by 1915. It was the first dam and reclamation project on the Colorado River and workers had to overcome many natural and logistical obstacles to build and maintain it. The Laguna Diversion Dam was replaced by the Imperial Dam as the Project's water source between 1941 and 1948. Today, it serves 275 farms and over 94,000 people.
