Mammoth Pool Reservoir
Mammoth Pool Reservoir is a reservoir on the San Joaquin River in the Sierra Nevada (U.S.), Sierra Nevada, within the Sierra National Forest in California. It creates the border between Fresno County, California, Fresno County and Madera County, California, Madera County. It is about north-northeast of Fresno, California, Fresno. Hydroelectric power The reservoir is formed by Mammoth Pool Dam, an earth-fill dam completed in 1960. It was built by Southern California Edison for hydroelectricity production. The dam's power plant can produce up to 190 megawatts. The dam, reservoir and power plant are part of the Big Creek Hydroelectric Project, perhaps the most extensive hydroelectric system in the world. Recreation The reservoir is also a recreation area. Activities at the lake include, swimming, fishing, camping and boating. The reservoir is closed to the public during the month of May and the first half of June to allow migrating deer to swim across the reservoir so as to spend ...

Sierra National Forest
Sierra National Forest is a U.S. national forest located on the western slope of central Sierra Nevada in Central California and bounded on the northwest by Yosemite National Park and the south by Kings Canyon National Park. The forest is known for its mountain scenery and beautiful lakes. Forest headquarters are located in Clovis, California. There are local ranger district offices in North Fork and Prather. History Sierra National Forest was the second National Forest created in California and the largest at the time. It covered over six million acres (24,000 km2) of the Sierra Nevada and was about four times the average area of typical California National Forests. Originally it embraced parts of eight counties from Tuolumne on the north to Kern on the south and Mono and Inyo on the east. Initially its name was descriptive, but later when the Sierra was divided into different units this was no longer the case. President Harrison proclaimed the Sierra Forest Reserv ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, 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.

Landforms Of The Sierra Nevada (United States)
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoirs In Madera County, California
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...

List Of Lakes In California
There are more than 3,000 named lakes, reservoirs, and dry lakes in the U.S. state of California. Largest lakes In terms of area covered, the largest lake in California is the Salton Sea, a lake formed in 1905 which is now saline. It occupies in the southeast corner of the state, but because it is shallow it only holds about of water. Tulare Lake in the San Joaquin Valley was larger, at approximately , until it was drained during the later years of the nineteenth century. In terms of volume, the largest lake on the list is Lake Tahoe, located on the California–Nevada border. It holds roughly of water. It is also the largest freshwater lake by area, at , and the deepest lake, with a maximum depth of . Among freshwater lakes entirely contained within the state, the largest by area is Clear Lake, which covers . Many of California's large lakes are actually reservoirs: artificial bodies of fresh water. In terms of both area and volume, the largest of these is Lake S ...

Creek Fire (2020)
The Creek Fire was a large wildfire which started on September 4, 2020, near Shaver Lake, California, and became one of the largest fires of the 2020 California wildfire season. The fire burned and was declared 100% contained on December 24, 2020. The fire burned mostly in the Sierra National Forest. The Creek Fire was the fifth-largest wildfire in modern California history, and the second-largest single fire not part of a greater complex. The fire necessitated the rescue of hundreds of people by National Guard helicopters. Evacuations were issued in North Fork, Bass Lake, Big Creek, Shaver, Huntington Lake, Tollhouse and Auberry, California. Half the homes in Big Creek were reported to have been destroyed by the fire. The Creek Fire destroyed at least 856 buildings and cost over $193 million (2020 USD) in fire suppression costs, while the total property damage is currently unknown. Events The fire began around 6:40 PM PDT on Friday, September 4, 2020, in the Big Creek dra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowplow
A snowplow (also snow plow, snowplough or snow plough) is a device intended for mounting on a vehicle, used for removing snow and ice from outdoor surfaces, typically those serving transportation purposes. Although this term is often used to refer to vehicles mounting such devices, more accurately they are known as winter service vehicles, especially in areas that regularly receive large amounts of snow every year, or in specific environments such as airfields. In other cases, pickup trucks and front end loaders are outfitted with attachments to fulfill this purpose. Some regions that do not frequently see snow may use graders to remove compacted snow and ice off the streets. Snowplows can also be mounted on rail cars or locomotives to clear railway tracks. Usage A snowplow works by using a blade to push snow to the side to clear it from a surface. Modern plows may include technology to make it easier to perform the work and stay on the road. These include Global Positioning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Creek Hydroelectric Project
The Big Creek Hydroelectric Project is an extensive hydroelectric power scheme on the upper San Joaquin River system, in the Sierra Nevada of central California. The project is owned and operated by Southern California Edison (SCE). The use and reuse of the waters of the San Joaquin River, its South Fork, and the namesake of the project, Big Creek – over a vertical drop of – have over the years inspired a nickname, "The Hardest Working Water in the World". The primary purpose of the project was to provide electric power for the fast-growing city of Los Angeles. California engineer John S. Eastwood was the principal designer of the system, which was initially funded and built by Henry E. Huntington's Pacific Light and Power Company (PL&P). Construction of the system's facilities started in 1911, and the first power was transmitted to Los Angeles in 1913. After SCE acquired PL&P in 1917, the system was gradually expanded to its present size, with the last powerhouse coming on l ...

Power Plant
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built by Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern California Edison
Southern California Edison (or SCE Corp), the largest subsidiary of Edison International, is the primary electricity supply company for much of Southern California. It provides 15 million people with electricity across a service territory of approximately 50,000 square miles. However, the Los Angeles Department of Water and Power, San Diego Gas & Electric (SDG&E), Imperial Irrigation District, and some smaller municipal utilities serve substantial portions of the southern California territory. The northern part of the state is generally served by the Pacific Gas & Electric Company of San Francisco. Other investor-owned utilities (IOUs) in California include SDG&E, PacifiCorp, Bear Valley Electric, and Liberty Utilities. Southern California Edison (SCE) still owns all of its electrical transmission facilities and equipment, but the deregulation of California's electricity market in the late 1990s forced the company to sell many of its power plants, though some were probably sold ...
