Lake Margaret (Tasmania)
Lake Margaret is a concrete-faced gravity dam with an spillway, uncontrolled spillway across the Yolande River, located on the north side of Mount Sedgwick (Tasmania), Mount Sedgwick, in the West Coast Range, West Coast, Tasmania, West Coast of Tasmania, Australia. The impounded reservoir is also called Lake Margaret. The dam was constructed in 1918 by the Mount Lyell Mining and Railway Company for the purpose of generating hydro-electricity, hydro-electric power via the Lake Margaret Power Station, which is located below the dam wall. Following the closure of the Mount Lyell Mining and Railway Company, in 1985 the control of the dam, lake, and power station was transferred to Hydro Tasmania. Features and location The dam, called Lake Margaret, was completed in 1918 and it was the first gravity dam constructed in Tasmania. It was built of concrete with conglomerate "plums". The dam wall is high and is long and the concrete-faced dam wall has a volume of . The uncontrolled s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydro-electricity
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.

Pipeline Transport
Pipeline transport is the long-distance transportation of a liquid or gas through a system of pipes—a pipeline—typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries of the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. ''Pipeline and Gas Journals worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels – such as oil, natural gas and biofuels – and other fluids including sewage, slurry, water, beer, hot water or steam for shorter distances. Pipelines are useful for transporting water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodstave
] A stave is a narrow length of wood with a slightly bevelled edge to form the sides of barrels, tanks, tubs, vats and pipelines, originally handmade by coopers. They have been used in the construction of large holding tanks and penstocks at hydro power developments. They are also used in the construction of certain musical instruments with rounded bodies or backs. See also *Rubicon Hydroelectric Scheme, which has wood stave penstocks on operating power stations *Lake Margaret Power Station The Lake Margaret Power Stations comprise two hydroelectric power stations located in Western Tasmania, Australia.

Pelton Turbine
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] |
Lake Beatrice
Lake Beatrice is a natural lake on the lower eastern side of Mount Sedgwick in the West Coast Range of Western Tasmania, Australia. Lake Beatrice is higher in altitude than the nearby Lake Burbury; however, it is not visible from that level, but can be seen either from the air or the higher slopes of the eastern part of Mount Lyell or the upper levels of Mount Sedgwick. The lake was a reference point for the planned Great Western Railway The Great Western Railway (GWR) was a British railway company that linked London with the southwest, west and West Midlands of England and most of Wales. It was founded in 1833, received its enabling Act of Parliament on 31 August 1835 and ran ... that was considered at the end of the nineteenth century; however was never built.

Tasmap
Tasmap is the main government authority for the state of Tasmania in Australia for the mapping and management of land information systems for the state. In earlier decades most Australian mapping departments were known by the common name of the ''Lands and Surveys departments'', however marketing and other factors have simplified the names of such departments. The current Tasmanian government department umbrella for the Tasmap operations is the Department of Primary Industries, Parks, Water and Environment. The range of products from the authority include: * Cadastral/Topographic maps in the 1:25000 scale * Topographic maps in 1:250,000 and 1:100,000 * Digital mapping products As well as a range of atlases and maps serving various purposes, it provides a series of national park maps.

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Sedgwick, Tasmania
Mount Sedgwick is a mountain located within the West Coast Range, in the West Coast region of Tasmania, Australia. It lies in line behind Mount Lyell in views from high points in Queenstown and from the roads leading out to Strahan and Zeehan. Bands of the pink and grey coloured conglomerate show strikingly on its south west slopes. Its western and south western slopes are significantly more precipitous and rocky, compared to the once heavily forested southern and south eastern slopes. Geology The geology of Mount Sedgwick has remnant Jurassic, Permian and Palaeozoic features. The top of Mount Sedgwick is columnar jointed Jurassic Dolerite interpreted as a remnant of a dolerite sheet. The lack of a strong magnetic signature suggests it is not a plug that intrudes Permian tillite, which is exposed on the South East flank of the mountain. Mount Sedgwick and its surrounding area was identified in the 1890s by Thomas Bather Moore as being associated with evidence of glaciation ...

Zeehan Highway
Zeehan Highway (also known as the Queenstown-Zeehan road) is a road between Zeehan and Queenstown in Western Tasmania. Where it leaves the valley in which Queenstown lies, it is the junction with the Queenstown to Strahan road that is at Howards Plains on higher ground, that the highway proceeds north. A little further north is the turnoff for the Lake Margaret Power Station, and then the turnoff for Anthony Road. It crosses the Dundas River, Henty and Yolande rivers. Although it was considered much earlier it was being planned in the 1930s, following the completion of the Lyell Highway. It was not completed until the 1960s, causing the Mount Lyell Mining and Railway Company to ship copper out of Queenstown via the Mount Lyell railway (now the West Coast Wilderness Railway) until the time of its completion. It was the part of the route for trucks hauling copper ore from Mount Lyell Mining and Railway Company from the Queenstown mine to Melba Flats between 1962 and 1994 ...

Henty River
The Henty River is a perennial river in the West Coast region of Tasmania, Australia. The river generally lies north of and south of . Location and features Formed by the confluence of the Dobson and Newton Creeks, the river rises below Lake Newton on the western slopes of the Tyndall Range, northwest of Mount Tyndall, part of the West Coast Range of Tasmania. The river flows generally south by west and then west, joined by eight tributaries. : Bottle Creek : Lost Creek : Malcolm Creek : McCutcheom's Creek : Tully : Yolande :Badger The mouth emptying into the Southern Ocean at Henty Dunes. The river descends over its course. In the area known as the Upper Henty at the river's headwaters is the Henty Gold Mine. Its upper reaches were some of the last sites of dam making by the Hydro Tasmania in its long history of regulating flow of Tasmanian rivers. The river catchment has two areas of high ground. One is known as the ''Professor Plateau'', west of the ''Professor Range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
