Pyramid Lake (Los Angeles County, California)
Pyramid Lake is a reservoir formed by Pyramid Dam on Piru Creek in the eastern Topatopa Mountains, near Castaic, Southern California. It is a part of the West Branch California Aqueduct, which is a part of the California State Water Project. Its water is fed by the system after being pumped up from the San Joaquin Valley and through the Tehachapi Mountains. Background This lake was created in 1972, and completed in 1973, as a holding reservoir for the California State Water Project. The lake was named after a pyramid-shaped rock carved out by engineers building U.S. Route 99. Travelers between Los Angeles and Bakersfield christened the landmark “Pyramid Rock,” which still stands just adjacent to the dam. The earth and rock dam was built by the California Department of Water Resources and was completed in 1973. Pyramid Lake is part of the California Aqueduct, which is part of the California State Water Project. Outflow goes downstream to Castaic Lake, which ...

Topatopa Mountains
The Topatopa Mountains are a mountain range in Ventura County, California, north of Ojai, Santa Paula, and Fillmore. They are part of the Transverse Ranges of Southern California. Etymology A name for the mountains was first inscribed within the archives of Mission Basilica San Buenaventura in 1943, citing a nearby Chumash ranchería named "Si-toptopo". In 1945, American linguist and ethnologist John Peabody Harrington noted that "topa" is a Chumash word meaning " reed" or " rush". Geography The Topatopa Mountains lie in an east–west direction east of the Sierra Madre Mountains, and west of the Sierra Pelona Mountains. To the south lies the Santa Clara River Valley into which various creeks drain starting in the mountains into the Santa Clara River. The range reaches an elevation of at Cobblestone Mountain, about north-northeast of Fillmore and about northwest of Castaic. Snow frequently falls on the high peaks during winter.

Aqueduct (watercourse)
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term ''aqueduct'' is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term ''aqueduct'' also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, the ancient Near East, ancient Rome, ancient Aztec, and ancient Inca. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water. Etymology The word ''aqueduct'' is derived from the Latin words (''water'') and (''led'' or ''guided''). Ancient aqueducts Although particularly ...

Santa Clara River (California)
The Santa Clara River () is an longU.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 16, 2011 river in Ventura and Los Angeles counties in Southern California. It drains parts of four ranges in the Transverse Ranges System north and northwest of Los Angeles, then flows west onto the Oxnard Plain and into the Santa Barbara Channel of the Pacific Ocean. The watershed has provided habitat for a wide array of native plants and animals and has historically supplied humans with water, fish, and fertile farmland. The northern portion of the watershed was home to the Tataviam people while the southern portion was occupied by the Chumash people. Much of the Santa Clara River Valley is used for agriculture which has limited the use of structural levees to separate the natural floodplain from the river. Although it is one of the least altered rivers in Southern California, some levees exist where the river flows through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rancho Temescal
Rancho Temescal was a Mexican land grant in present-day Ventura County and Los Angeles County, California given in 1843 by Governor Manuel Micheltorena to Francisco Lopez and José Arellanes. The word “temescal” is Spanish for "sweat bath" or "sweat lodge", deriving from the Nahuatl “temazcalli”. The grant was located in the upper end of the Santa Clara Valley, in the eastern section of Ventura County, in the upper Santa Clara River Valley near the base of the Topatopa Mountains where Piru Creek and the Santa Clara River meet. The grant encompassed present-day Lake Piru and town of Piru. History Francisco Lopez and José Arellanes were granted three square league Rancho Temescal in 1843. The grant was later transferred to Ramon de la Cuesta and Francisco Gonzales Ciminio. With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored. As required by the L ...

Ridge Route
The Ridge Route, officially the Castaic–Tejon Route and colloquially known as the Grapevine, was a two-lane highway between Los Angeles County and Kern County, California. Opened in 1915 and paved with concrete between 1917 and 1921, the road was the first paved highway directly linking the Los Angeles Basin with the San Joaquin Valley (southern Central Valley) over the Tejon Pass and the rugged Sierra Pelona Mountains ridge south of Gorman. Much of the old road runs through the Angeles National Forest, and passes many historical landmarks, including the National Forest Inn, Reservoir Summit, Kelly's Half Way Inn, Tumble Inn, and Sandberg's Summit Hotel. North of the forest, the Ridge Route passed through Deadman's Curve before ending at Grapevine. The road was originally built as a state highway, a segment of the unsigned Legislative Route 4, before it became signed as part of U.S. Route 99 (US 99) in 1926. The road was then bypassed by the three-lane Ridge R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.
