Cat Arm Hydro Electric Development
The Cat Arm Generating Station is located on the Great Northern Peninsula of Newfoundland and makes use of 380.5 m of head between the reservoir and White Bay. Each of the two units operates with an average rated flow of 20 m3/s to generate a total 127 MW of electrical power with an average annual production of 733 GWh. The two 63.5 MW units, equipped with pelton turbines, were first synchronized on February 10 and 12, 1985. The watershed of the Cat Arm River was located on a plateau with an average elevation of approximately 518 m on the raised uplands of the Long Range Mountains. The project involved the creation of a reservoir with a surface area of approximately 53 square kilometres by the erection of one main dam A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use ... and seven ...

Great Northern Peninsula
The Great Northern Peninsula (Inuttitut: ''Ikkarumiklua'') is the largest and longest peninsula of Newfoundland, Canada, approximately 270 km long and 90 km wide at its widest point and encompassing an area of 17,483 km2. It is defined as that part of Newfoundland from Bonne Bay northwards around Cape Norman and Cape Bauld and thence southwards to the head of White Bay, bounded by the Gulf of St. Lawrence on the west, the Strait of Belle Isle on the north and the Labrador Sea and White Bay on the east. The vast majority of the peninsula is located within Division No. 9, Newfoundland and Labrador, except for the southeastern corner, which is part of Subdivision G of Division No. 5, Newfoundland and Labrador. In 1991, the peninsula had 23,854 inhabitants. By 2016, however, the population had decreased to 15,607, further decreased to 14,733 in 2021. St. Anthony is the largest population centre on the peninsula. A ferry service operates at the western part of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newfoundland And Labrador
Newfoundland and Labrador (; french: Terre-Neuve-et-Labrador; frequently abbreviated as NL) is the easternmost province of Canada, in the country's Atlantic region. The province comprises the island of Newfoundland and the continental region of Labrador, having a total size of 405,212 square kilometres (156,500 sq mi). In 2021, the population of Newfoundland and Labrador was estimated to be 521,758. The island of Newfoundland (and its smaller neighbouring islands) is home to around 94 per cent of the province's population, with more than half residing in the Avalon Peninsula. Labrador borders the province of Quebec, and the French overseas collectivity of Saint Pierre and Miquelon lies about 20 km west of the Burin Peninsula. According to the 2016 census, 97.0 per cent of residents reported English as their native language, making Newfoundland and Labrador Canada's most linguistically homogeneous province. A majority of the population is descended from English and Irish s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir (water)
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 ...

Pelton Wheel
The Pelton wheel or Pelton Turbine is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many earlier variations of impulse turbines existed, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ran at half the speed of the water jet, the water left the wheel with very little speed; thus his design extracted almost all of the water's impulse energywhich made for a very efficient turbine. History file:Pelton wheel (patent).png, Figure from Lester Allan Pelton's original October 1880 patent Lester Allan Pelton was born in Vermillion, Ohio in 1829. In 1850, he traveled overland to take part in the California Gold Rush. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cat Arm River
The cat (''Felis catus'') is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is commonly referred to as the domestic cat or house cat to distinguish it from the wild members of the family. Cats are commonly kept as house pets but can also be farm cats or feral cats; the feral cat ranges freely and avoids human contact. Domestic cats are valued by humans for companionship and their ability to kill rodents. About 60 cat breeds are recognized by various cat registries. The cat is similar in anatomy to the other felid species: they have a strong flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey. Their night vision and sense of smell are well developed. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling, and grunting as well as cat-specific body language. Although the cat is a social species, they are a solitary hunter. As ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Range Mountains
The Long Range Mountains are a series of mountains along the west coast of the Canadian island of Newfoundland. The long range mountains form the northernmost section of the Appalachian mountain chain on the eastern seaboard of North America. Mapping of the Great Northern Peninsula was first done in the early 1900s by Mattie Mitchell, Mi'kmaq chieftain, guide and explorer. In 2003, it was announced that the International Appalachian Trail would be extended through the Long Range Mountains. A portion of the trail opened in 2006. Description The Great Northern Peninsula of Western Newfoundland contains the Highlands, the largest external basement massif of the Grenville Orogeny in the Appalachian Orogen. This Precambrian basement is known as the Long Range Inlier, Long Range Complex or Basement Gneiss Complex, consisting of quartz-feldspar gneisses and granites that are up to 1,550 million years in age. The Long Range dikes are mafic in composition and have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Newfoundland And Labrador
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power Stations In Newfoundland And Labrador
Hydroelectricity, or hydroelectric power, is 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 sources combined and also more than nuclear power. Hydropower can provide large amounts of 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.
