Great Lake (Tasmania)
The Great Lake, officially yingina / Great Lake, is a natural lake and man-made reservoir that is located in the central northern region of Tasmania, Australia. Location and features Fed by the Pine Rivulet and Breton Rivulet, the original natural freshwater lake, much smaller in size than its current surface area, was expanded as a result of the 1922 construction of Miena Dam #2 at its southern outflow into the Shannon River. This dam is considered to be of high heritage value by Engineers Australia. Miena Dam #2 created the once-famous ''Shannon Rise'', in the 500-metre section of the Shannon River between the dam and Shannon Lagoon. The hatching of thousands of caddis moths in early summer, attracted large numbers of trout and fishermen. In 1967, a sloping-core rock-fill dam was built just downstream of Miena Dam #2 to increase the maximum-capacity level, destroying the ''Shannon Rise''. It was raised a further in 1982, causing Miena Dam #2 to be periodically submerg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Highlands (Tasmania)
The Central Highlands is a region in Tasmania, Australia where geographical and administrative boundaries closely coincide. It is also known as ''The Lake Country of Tasmania''. Geographical region The mountains of Central Tasmania are mainly found in four different conservation reserves: * Cradle Mountain-Lake St Clair National Park - in the western part * Walls of Jerusalem National Park - in the central part * Central Plateau Conservation Area in the eastern part Administrative region The Central Highlands Council incorporates most of the highland region. Former Hydro communities Early power developments by Hydro Tasmania in the Central Highlands included the communities of workers who were employed in construction. Significant numbers of the communities were migrants to Australia The Tarraleah Power Station, Tarraleah community was one established in 1934 which was a significant early community for the Upper Derwent Power Development. The part of Tarraleah known as ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian National Committee On Large Dams
The Australian National Committee on Large Dams (abbreviated as ANCOLD) is an Australian-based non-government, non-profit and voluntary association of organisations and individual professionals with a common technical interest in large dams and their environs. ANCOLD is not an advocate for dams but an apolitical industry body that focuses on disseminating knowledge, developing capability and providing guidance on all aspects of dam engineering, management and associated issues. ANCOLD is a member of the International Commission on Large Dams The International Commission on Large Dams, or ICOLD, (french: Commission Internationale des Grands Barrages ''or CIGB'') is an international non-governmental organization dedicated to the sharing of professional information and knowledge of the de ...

Lake Highway
The Lake Highway, or A5, is a main highway and A-road in Tasmania. Although still known as the Lake Highway the official title of the road was changed in 2001 to Highland Lakes Road. The Lake Highway branches off the Midland Highway at Melton Mowbray in southern Tasmania and continues for 152 kilometres, with Bothwell being the main town of any size en route, it terminates in Deloraine. Until recently it was the only major A-road in Australia that was partially unsealed; works to seal the road were completed in April 2019.Highland Lakes Road' The highway is one of the least used in Tasmania, except during the summer months when the road is used by Great Lake commuters. The portion of the highway on and near the Great Lake in Tasmania's Central plateau, averages a height of about 1000 metres. During the winter months it is sometimes snowed under. Two major roads that branch from the Lake Highway are the Marlborough Highway (which connects to the A10 Lyell Highway), and Poat ...

Shack
A shack (or, in some areas, shanty) is a type of small shelter or dwelling, often primitive or rudimentary in design and construction. Unlike huts, shacks are constructed by hand using available materials; however, whereas huts are usually rural and made of natural materials (mud, rocks, sticks, etc.) shacks are generally composed of scavenged man-made materials like abandoned construction debris, repurposed consumer waste and other useful discarded objects that can be quickly acquired at little or no cost and fashioned into a small dwelling. Background In areas of high population density and high poverty, shacks are often the most prevalent form of housing; it is possible that up to a billion people worldwide live in shacks. Fire is a significant hazard in tight-knit shack settlements. Settlements composed mostly or entirely of shacks are known as slums or shanty towns. In Australian English ''shack'' can also refer to a small holiday house with limited conveniences, for i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydro Tasmania
Hydro Tasmania, known for most of its history as the Hydro-Electric Commission (HEC) or The Hydro, is the trading name of the Hydro-Electric Corporation, a Tasmanian Government business enterprise which is the predominant electricity generator in the state of Tasmania, Australia. The Hydro was originally oriented towards hydro-electricity, due to Tasmania's dramatic topography and relatively high rainfall in the central and western parts of the state. Today Hydro Tasmania operates thirty hydro-electric and one gas power station, and is a joint owner in three wind farms. The Minister for Energy, currently the Hon. Guy Barnett MP, has portfolio responsibility for Hydro Tasmania. Hydro Tasmania operates under the ''Government Business Enterprises (GBE) Act'' 1995 and the ''Hydro-Electric Corporation Act'' 1995, and has a reporting requirement to the Treasurer of Tasmania, currently the Hon. Michael Ferguson (Australian politician) MP. Hydro Tasmania was projected to pay the Tasma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poatina Power Station
The Poatina Power Station is a conventional hydroelectric power station located in the Central Highlands region of Tasmania, Australia. The power station is situated on the Great Lake and South Esk and is owned and operated by Hydro Tasmania. Technical details Located in the Great Lake and South Esk catchment area, Poatina makes use of a descent from the Great Western Tiers to the Norfolk Plains in Tasmania's northern Midlands. Water from Great Lake is diverted via a tunnel to the edge of the Great Western Tiers where it plummets down a viable penstock line, which enters the ground again near the power station. The Poatina Power Station is located underground in a massive artificial cavern hence the name Poatina, Palawa for "cavern" or "cave". The headrace tunnel and penstocks were bored through mudstone with the aid of a Robbins Mole. Water leaves the power station via a roughly long tailrace tunnel and discharges into the Macquarie River via Brumbies Rivulet. Poatin ...

Tourism
Tourism is travel for pleasure or business; also the theory and practice of touring (other), touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tour (other), tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be Domestic tourism, domestic (within the traveller's own country) or International tourism, international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of t ...

Fishing
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans ( shrimp/ lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms ( starfish/ sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations ( fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead. Fishing has been an important part of human culture since hunter-gatherer times, and is one of the few food production activities that have persisted ...

Hydro-electric
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.

Australian Height Datum
The Australian Height Datum was introduced in 1971 as the official vertical datum for Australia, and thereby serves as the benchmark to which all height measurements are referred. The Australian Height Datum is an amalgamation of decades of spirit levelling work conducted by numerous state and territory authorities across the country, and was corrected to align with the mean sea level observations of thirty tide gauges positioned around the entire coastline. While it remains the published vertical datum for all surveying and engineering operations performed throughout Australia, newer technologies have uncovered numerous deficiencies, offsets and distortions within the Australian Height Datum, leading to discussions about defining a new Australian vertical datum. Background The National Mapping Council (pre-1945) Prior to the creation of the Australian Height Datum, levelling surveys were carried out by professional surveyors for construction and mapping purposes using only ...
