Castaic Creek
Castaic Creek (Chumashan languages, Chumash: ''Kaštiq'') is a , accessed March 16, 2011 stream in the Sierra Pelona Mountains, in northeastern Los Angeles County, California. It is a tributary of the Santa Clara River (California), Santa Clara River. Castaic Lake Castaic Dam on the creek forms Castaic Lake, but most of the water comes from the West Branch of the California Aqueduct#West Branch, West Branch California Aqueduct, part of the California State Water Project. The lake is the terminus for west branch of the aqueduct. The aqueduct delivers water to the lake by a pipeline from Pyramid Lake (Los Angeles County, California), Pyramid Lake. Besides storing drinking water, Castaic Lake is the lower reservoir in a Pumped-storage hydroelectricity, pumped-storage hydroelectric system. During times of peak electricity demand, water is released from Pyramid Lake and run through the water turbine, turbines at Castaic Power Plant. At night, when demand and electricity prices are ...

Pumped-storage Hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivers Of Los Angeles County, California
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

San Francisquito Creek (Santa Clara River)
San Francisquito Creek, in Los Angeles County, is a tributary stream of the Santa Clara River. It drains the south facing slopes of the Sierra Pelona Mountains of the San Gabriel Mountains within the Transverse Range of California, United States. The closest populated place to the creek is Green Valley that lies along the upper course of the creek, in the upper part of San Francisquito Canyon, southeast of the source of the Creek at San Francisquito Pass. At its mouth and confluence with the Santa Clara River is Santa Clarita. History Originally called the Arroyo San Francisquito, San Francisquito Creek and its canyon was for many years the major route of wagon and stage roads northward from Los Angeles into the San Joaquin Valley. The first was El Camino Viejo, later there was the Stockton–Los Angeles Road and the Butterfield Overland Mail stage route. The wagon road followed the course of the stream in the bottom of the canyon. Two stage stations for the Overland Mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santa Clarita, California
Santa Clarita (; Spanish for "Little St. Clare") is a city in northwestern Los Angeles County in the U.S. state of California. With a 2020 census population of 228,673, it is the third-largest city by population in Los Angeles County, the 17th-largest in California, and the 99th-largest city in the United States. It is located about northwest of downtown Los Angeles, and occupies of land in the Santa Clarita Valley, along the Santa Clara River. It is a notable example of a U.S. edge city, satellite city, or boomburb. Human settlement of the Santa Clarita Valley dates back to the arrival of the Chumash people, who were displaced by the Tataviam circa 450 AD. After Spanish colonists arrived in Alta California, the Rancho San Francisco was established, covering much of the Santa Clarita Valley. Henry Mayo Newhall purchased the Rancho San Francisco in 1875 and established the towns of Saugus and Newhall. The Newhall Land and Farming Company played a major role in the city's de ...

Aquifer
An aquifer is an underground layer of water-bearing, permeable rock, rock fractures, or unconsolidated materials (gravel, sand, or silt). Groundwater from aquifers can be extracted using a water well. Aquifers vary greatly in their characteristics. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Related terms include aquitard, which is a bed of low permeability along an aquifer, and aquiclude (or ''aquifuge''), which is a solid, impermeable area underlying or overlying an aquifer, the pressure of which could create a confined aquifer. The classification of aquifers is as follows: Saturated versus unsaturated; aquifers versus aquitards; confined versus unconfined; isotropic versus anisotropic; porous, karst, or fractured; transboundary aquifer. Challenges for using groundwater include: overdrafting (extracting groundwater beyond the Dynamic equilibrium, equilibrium yield of the aquifer), groundwater-related subsidence of land, gro ...

Groundwater Recharge
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and or reclaimed water is routed to the subsurface. Processes Water is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). Recharge may be impeded somewhat by human activities including paving, development, or logging. These activities can result in loss of topsoil resulting in reduced water infiltration, enhanced surface runoff and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tehachapi Mountains
The Tehachapi Mountains (; Kawaiisu: ''Tihachipia'', meaning "hard climb") are a mountain range in the Transverse Ranges system of California in the Western United States. The range extends for approximately in southern Kern County and northwestern Los Angeles County and form part of the boundary between the San Joaquin Valley and the Mojave Desert. Geography The Tehachapis form a geographic, watershed, habitat, and rain shadow divide separating the San Joaquin Valley to the northwest and the Mojave Desert to the southeast. The Tehachapis' crest varies in height from approximately . They are southeast of Bakersfield and the Central Valley, and west of Mojave and the Antelope Valley. The range runs southwest to northeast (SW-NE) connecting the Southern Sierra Nevada range on their northeast with the San Emigdio Mountains on the west and Sierra Pelona Mountains on the southwest.

Castaic Power Plant
Castaic Power Plant, also known as the Castaic Pumped-Storage Plant, is a seven unit pumped-storage hydroelectric plant, operated by the Los Angeles Department of Water and Power, which provides peak load power from the falling water on the West Branch of the California State Aqueduct. It is a cooperative venture between the LADWP and the Department of Water Resources of the State of California. An agreement between the two organizations was signed on September 2, 1966, for construction of the project. Location The Castaic Power Plant is located about from the northern Los Angeles city limits at the upper end of the West arm of Castaic Lake. Water supply California State Aqueduct water en route to Southern California is pumped up through the Tehachapi Mountains (by the Edmonston Pumping Plant) to the Tehachapi Afterbay. There the aqueduct divides into East and West Branches. The West Branch water is again pumped at the Oso Pumping Plant to Quail Lake, near Highway 138 Eas ...

Water Turbine
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy. History Water wheels have been used for hundreds of years for industrial power. Their main shortcoming is size, which limits the flow rate and head that can be harnessed. The migration from water wheels to modern turbines took about one hundred years. Development occurred during the Industrial revolution, using scientific principles and methods. They also made extensive use of new materials and manufacturing methods developed at the time. Swirl The word turbine was introduced by the French engineer Claude Burdin in the early 19th century and is derived from the Greek word "τύρβη" ...
