Peripheral Canal
The Peripheral Canal was a series of proposals starting in the 1940s to divert water from California's Sacramento River, around the periphery of the San Joaquin-Sacramento River Delta, to uses farther south. The canal would have attempted to resolve a problem with the quality of water pumped south. Pumps create such a powerful suction that the boundary between freshwater to saltwater has shifted inland, negatively affecting the environment. The pumps have increased by the amount of water exported each year to the Central Valley and Southern California. However, the peripheral canal as proposed would have reduced the overall freshwater flow into the Delta and move the freshwater-saltwater interface further inland, causing damage to Delta agriculture and ecosystems. Water project impact Before the Central Valley Project and State Water Project were built, all freshwater—primarily runoff from the Sierra Nevada—entering the Sacramento–San Joaquin River Delta flowed into San ...

Central Valley Project
The Central Valley Project (CVP) is a federal power and water management project in the U.S. state of California under the supervision of the United States Bureau of Reclamation (USBR). It was devised in 1933 in order to provide irrigation and municipal water to much of California's Central Valley—by regulating and storing water in reservoirs in the northern half of the state (once considered water-rich but suffering water-scarce conditions more than half the year in most years), and transporting it to the water-poor San Joaquin Valley and its surroundings by means of a series of canals, aqueducts and pump plants, some shared with the California State Water Project (SWP). Many CVP water users are represented by the Central Valley Project Water Association. In addition to water storage and regulation, the system has a hydroelectric capacity of over 2,000 megawatts, and provides recreation and flood control with its twenty dams and reservoirs. It has allowed major cities to gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California is a U.S. state, state in the Western United States, located along the West Coast of the United States, Pacific Coast. With nearly 39.2million residents across a total area of approximately , it is the List of states and territories of the United States by population, most populous U.S. state and the List of U.S. states and territories by area, 3rd largest by area. It is also the most populated Administrative division, subnational entity in North America and the 34th most populous in the world. The Greater Los Angeles area and the San Francisco Bay Area are the nation's second and fifth most populous Statistical area (United States), urban regions respectively, with the former having more than 18.7million residents and the latter having over 9.6million. Sacramento, California, Sacramento is the state's capital, while Los Angeles is the List of largest California cities by population, most populous city in the state and the List of United States cities by population, ...

Dianne Feinstein
Dianne Goldman Berman Feinstein ( ; born Dianne Emiel Goldman; June 22, 1933) is an American politician who serves as the senior United States senator from California, a seat she has held since 1992. A member of the Democratic Party, she was mayor of San Francisco from 1978 to 1988. Born in San Francisco, Feinstein graduated from Stanford University in 1955. In the 1960s, she worked in local government in San Francisco. Feinstein was elected to the San Francisco Board of Supervisors in 1969. She served as the board's first female president in 1978, during which time the assassinations of Mayor George Moscone and City Supervisor Harvey Milk by Dan White drew national attention. Feinstein succeeded Moscone as mayor and became the first woman to serve in that position. During her tenure, she led the renovation of the city's cable car system and oversaw the 1984 Democratic National Convention. Despite a failed recall attempt in 1983, Feinstein was a very popular mayor and was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canals In California
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal.
