Irrigation is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation.
The Reclamation Act of 1902 is a United States federal law that funded irrigation projects for the arid lands of 17 states in the American West.
Special districts are independent, special-purpose governmental units that exist separately from local governments such as county, municipal, and township governments, with substantial administrative and fiscal independence. They are formed to perform a single function or a set of related functions. The term special district governments as defined by the U.S. Census Bureau excludes school districts. In 2017, the U.S. had more than 51,296 special district governments.
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.
Tribal sovereignty in the United States is the concept of the inherent authority of Indigenous tribes to govern themselves within the borders of the United States.
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), but that was subsequently limited to 320.
Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers.
The All-American Canal is an 82-mile-long (132 km) aqueduct, located in southeastern California. It conveys water from the Colorado River into the Yuma Project, the Imperial Valley, and to nine cities. It is the Imperial Valley's only water source, and replaced the Alamo Canal, which was located mostly in Mexico. The Imperial Dam, about 30 miles (48 km) northeast of Yuma, Arizona on the Colorado River, diverts water into the All-American Canal, which runs to just west of Calexico, California before its last branch heads mostly north into the Imperial Valley. Smaller canals branching off the All-American Canal move water into the Yuma Valley and the Imperial Valley. These canal systems irrigate up to 630,000 acres (250,000 ha) of crop land and have made possible a greatly increased crop yield in this area, originally one of the driest on earth. It is the largest irrigation canal in the world, carrying a maximum of 26,155 cubic feet per second (740.6 m3/s). Agricultural runoff from the All-American Canal drains into the Salton Sea.
Water right in water law is the right of a user to use water from a water source, e.g., a river, stream, pond or source of groundwater. In areas with plentiful water and few users, such systems are generally not complicated or contentious. In other areas, especially arid areas where irrigation is practiced, such systems are often the source of conflict, both legal and physical. Some systems treat surface water and ground water in the same manner, while others use different principles for each.
The economy of the State of California is the largest in the United States, with a $3.944 trillion gross state product (GSP) as of 2023. It is the largest sub-national economy in the world. If California were a nation it would rank in terms of nominal GDP as the world's fifth largest economy, behind Japan and ahead of India. Additionally, California's Silicon Valley is home to some of the world's most valuable technology companies, including Apple, Alphabet, and Nvidia. In total, 11 of the Fortune 100 companies and 53 of the Fortune 500 companies are headquartered in California.
The American Falls Dam is a concrete gravity-type dam in the western United States, located near American Falls, Idaho, on river mile 714.7 of the Snake River. The dam and reservoir are a part of the Minidoka Project on the Snake River Plain and are used primarily for flood control, irrigation, and recreation. When the original dam was built in the 1920s by the U.S. Bureau of Reclamation, the residents of American Falls were forced to relocate three-quarters of their town to make room for the reservoir.
The U.S. House Committee on Natural Resources or Natural Resources Committee is a Congressional committee of the United States House of Representatives. Originally called the Committee on Interior and Insular Affairs (1951), the name was changed to the Committee on Natural Resources in 1991. The name was shortened to the Committee on Resources in 1995 by the new chairman, Don Young. Following the Democratic takeover of the House of Representatives in 2006, the name of the committee was changed back to its title used between 1991 and 1995.
In 2021, the economy of the State of Colorado was 16th largest in the United States with a gross state product of $421 billion.Colorado's per capita personal income in 2019 was $61,157, putting Colorado 12th in the nation.
Southwestern Idaho is a geographical term for the area along the U.S. state of Idaho's borders with Oregon and Nevada. It includes the populous areas of the Boise metropolitan area and the Treasure Valley.
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:
Modern United States wind energy policy coincided with the beginning of modern wind industry of the United States, which began in the early 1980s with the arrival of utility-scale wind turbines in California at the Altamont Pass wind farm. Since then, the industry has had to endure the financial uncertainties caused by a highly fluctuating tax incentive program. Because these early wind projects were fueled by investment tax credits based on installation rather than performance, they were plagued with issues of low productivity and equipment reliability. Those investment tax credits expired in 1986, which forced investors to focus on improving the reliability and efficiency of their turbines. The 1990s saw rise to a new type of tax credit, the production tax credit, which propelled technological improvements to the wind turbine even further by encouraging investors to focus on electricity output rather than installation.
Hydropower policy in the United States includes all the laws, rules, regulations, programs and agencies that govern the national hydroelectric industry. Federal policy concerning waterpower developed over considerable time before the advent of electricity, and at times, has changed considerably, as water uses, available scientific technologies and considerations developed to the present day; over this period the priority of different, pre-existing and competing uses for water, flowing water and its energy, as well as for the water itself and competing available sources of energy have changed. Increased population and commercial demands spurred this developmental growth and many of the changes since, and these affect the technology's use today.
