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] |
Mouth (river)
A river mouth is where a river flows into a larger body of water, such as another river, a lake/reservoir, a bay/gulf, a sea, or an ocean. At the river mouth, sediments are often deposited due to the slowing of the current reducing the carrying capacity of the water. The water from a river can enter the receiving body in a variety of different ways. The motion of a river is influenced by the relative density of the river compared to the receiving water, the rotation of the earth, and any ambient motion in the receiving water, such as tides or seiches. If the river water has a higher density than the surface of the receiving water, the river water will plunge below the surface. The river water will then either form an underflow or an interflow within the lake. However, if the river water is lighter than the receiving water, as is typically the case when fresh river water flows into the sea, the river water will float along the surface of the receiving water as an overflow.

Tully River (Tasmania)
The Tully River is a river located in Far North Queensland, Australia. Course and features The Tully River rises in the Cardwell Range, part of the Great Dividing Range on the northern boundary of the Kirrama State Forest. The river flows generally north through Lake Koombooloomba and flows over the Tully Falls near and descends through the Tully Gorge within the Tully Gorge National Park, part of the UNESCO World Heritagelisted Wet Tropics site. Below the dam wall, the river is joined by five minor tributaries before emptying into the Coral Sea at Tully Heads. The river descends over its course. People and land use The Tully, together with the Herbert and the Burdekin rivers, were part of the proposed Bradfield Scheme to divert the upper reaches of the three rivers west of the Great Dividing Range and into the Thomson River designed to irrigate and drought-proof much of the western Queensland interior, as well as large areas of South Australia. The Scheme was proposed i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trout
Trout are species of freshwater fish belonging to the genera '' Oncorhynchus'', ''Salmo'' and ''Salvelinus'', all of the subfamily Salmoninae of the family Salmonidae. The word ''trout'' is also used as part of the name of some non-salmonid fish such as ''Cynoscion nebulosus'', the spotted seatrout or speckled trout. Trout are closely related to salmon and char (or charr): species termed salmon and char occur in the same genera as do fish called trout (''Oncorhynchus'' – Pacific salmon and trout, ''Salmo'' – Atlantic salmon and various trout, ''Salvelinus'' – char and trout). Lake trout and most other trout live in freshwater lakes and rivers exclusively, while there are others, such as the steelhead, a form of the coastal rainbow trout, that can spend two or three years at sea before returning to fresh water to spawn (a habit more typical of salmon). Arctic char and brook trout are part of the char genus. Trout are an important food source for humans and wildlife, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocean Beach (Tasmania)
Ocean Beach is a long stretch of beach running north of Macquarie Heads and Hells Gates on the West Coast of Tasmania. It is close to Strahan and parallel to the Strahan Airport runway. It extends as far north as Trial Harbour and the coast immediately west of Zeehan. Exposed to the ocean with no landmass at this longitude between it and South America, this beach can be exposed to extreme weather Extreme weather or extreme climate events includes unexpected, unusual, severe, or unseasonal weather; weather at the extremes of the historical distribution—the range that has been seen in the past. Often, extreme events are based on a locat ... conditions. In serious weather it can have large extended lines of breakers, and a swell at the Cape Sorell Waverider Buoy at up to 20+ metres. In the 1940s the beach area was utilised by local gliding and soaring club members Whale stranding frequently occurs along this stretch of the West Coast—and can be difficult to remedy d ...

Strahan–Zeehan Railway
The Strahan–Zeehan Railway, also known as the "Government Railway", was a railway from Strahan to Zeehan on the west coast of Tasmania. It linked two private railways: the Mount Lyell Mining and Railway Company railway line (now known as the West Coast Wilderness Railway) between Queenstown and Regatta Point, and the Emu Bay Railway between Zeehan and Burnie. Early photographs of the Strahan wharf and buildings adjacent taken from the north usually have the railway tracks in the lower section of the photograph, as the line followed the shore from Regatta Point around the bay before passing northward in what is considered to be West Strahan today. The line ran parallel to Ocean Beach before heading towards Zeehan. It was a critical link, due to the difficulties of shipping negotiating the entrance Macquarie Harbour and was essential during the 1912 North Mount Lyell disaster. The track gauge of the lines between Burnie was the same all the way to Queenstown. Flooding and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Zeehan-Strahan Road
Zeehan-Strahan Road (also known as the ''Strahan to Zeehan road'') is a road that links Strahan with Zeehan in Western Tasmania. It runs parallel to Ocean Beach for a distance and crosses the Henty River at the beach's northern end, before turning inland. In the 1920s, the main means of transport between the main centres of the west coast was by the available railways. Between Zeehan and Strahan, the only form of track was via Ocean Beach, otherwise the main mode was by the Strahan-Zeehan Railway. The feasibility of road connections was considered in terms of being able to allow for heavy haulage of ore and timber. The importance of the construction of roads in the West Coast was recognised in the 1920s but materialised in the 1960s or later. Following the early rough stages of the Zeehan Highway and the Strahan to Queenstown road it was possible to travel between Zeehan and Strahan in the 1940s. Following the demise of the railways in the 1960s, and the use of the ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Margaret, Tasmania
Lake Margaret is a concrete-faced gravity dam with an uncontrolled spillway across the Yolande River, located on the north side of Mount Sedgwick, in the West Coast Range, 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-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 spillway has a capacity of . In 1974 the dam wall was strengthened by the use ...

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] |
Henty Gold Mine
The Henty Gold Mine is located at the head of the Henty River on the edge of the West Coast Range in Western Tasmania. It is approximately 30 km north of Queenstown. It is east of Zeehan and south of Rosebery. It can be reached by the Hydro-built road that passes between the Henty River and Tullah. History Operations began in the 1990s. Its orebody and viability was ascertained from earlier exploration in the area during the 1970s when the priority was for other forms of mineralization within the Mount Read Volcanic Belt. Henty lies within the mineral rich Mt. Read Volcanic Belt in Western Tasmania that hosts the Hellyer, Que River, Rosebery, Hercules and Mount Lyell base metal deposits. The eastern side of the belt is dominated by the Henty Fault which runs north-east for over 60 kilometres between Mount Charter and Mount Read. The Henty operation is based on a series of structurally complex high-grade zones of gold mineralisation that occur within a package of highly a ...

Navigation
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.Bowditch, 2003:799. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks. All navigational techniques involve locating the navigator's position compared to known locations or patterns. Navigation, in a broader sense, can refer to any skill or study that involves the determination of position and direction. In this sense, navigation includes orienteering and pedestrian navigation. History In the European medieval period, navigation was considered part of the set of '' seven mechanical arts'', none of which were used for long voyages across open ocean. Polynesian navigation is probably the earliest form of open-ocean navigation; it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Badger River
Badgers are short-legged omnivores in the family Mustelidae (which also includes the otters, wolverines, martens, minks, polecats, weasels, and ferrets). Badgers are a polyphyletic rather than a natural taxonomic grouping, being united by their squat bodies and adaptions for fossorial activity. All belong to the caniform suborder of carnivoran mammals. The fifteen species of mustelid badgers are grouped in four subfamilies: four species of Melinae (genera ''Meles'' and ''Arctonyx'') including the European badger, five species of Helictidinae (genus ''Melogale'') or ferret-badger, the honey badger or ratel Mellivorinae (genus ''Mellivora''), and the American badger Taxideinae (genus ''Taxidae''). Badgers include the most basal mustelids; the American badger is the most basal of all, followed successively by the ratel and the Melinae; the estimated split dates are about 17.8, 15.5 and 14.8 million years ago, respectively. The two species of Asiatic stink badgers of the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
