Description The traditional owners of the area are the Noongar peoples. The lake is part of a dreaming trail that extends from the south coast near Augusta to the Great Victoria Desert country to the north east. Other features along the trail include Mulka's Cave, Wave Rock, Jilakin Rock, Jitarning Rock and Puntapin Rock. The explorers Henry Landor and Henry Maxwell Lefroy are usually credited with the discovery of Dumbleyung Lake, although it appears to have been shown on a map in 1839 with the name ''Kondening Lake''. Grazing leases around the lake were first granted to George Kersley in 1875. Dumbleyung Lake received world recognition when Donald Campbell broke the world water speed record on it on 31 December 1964, travelling at 444.66 km/h (276.3 mph) in his boat ''Blue ...

Donald Campbell
Donald is a masculine given name derived from the Gaelic name ''Dòmhnall''.. This comes from the Proto-Celtic *''Dumno-ualos'' ("world-ruler" or "world-wielder"). The final -''d'' in ''Donald'' is partly derived from a misinterpretation of the Gaelic pronunciation by English speakers, and partly associated with the spelling of similar-sounding Germanic names, such as ''Ronald''. A short form of ''Donald'' is ''Don''. Pet forms of ''Donald'' include ''Donnie'' and ''Donny''. The feminine given name ''Donella'' is derived from ''Donald''. ''Donald'' has cognates in other Celtic languages: Modern Irish ''Dónal'' (anglicised as ''Donal'' and ''Donall'');. Scottish Gaelic ''Dòmhnall'', ''Domhnull'' and ''Dòmhnull''; Welsh '' Dyfnwal'' and Cumbric ''Dumnagual''. Although the feminine given name ''Donna'' is sometimes used as a feminine form of ''Donald'', the names are not etymologically related.

Lakes Of The Great Southern (Western Australia)
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Lakes Of Australia
Natural freshwater lakes in Australia are rare due to the general absence of glacial and tectonic activity in Australia. Types Most lakes in Australia fall within one of five categories. Excluding lakes created by man-made dams for water storage and other purposes, one can identify the following: * coastal lakes and lagoons including perched lakes; * natural freshwater inland lakes, often ephemeral and some part of wetland or swamp areas; * the Main Range containing mainland Australia's five glacial lakes. In Tasmania, due to glaciation, there are a large number of natural freshwater lakes on the central plateau, many of which have been enlarged or modified by hydro-electric developments; * predominantly dry, salt lakes in the flat desert regions of the country lacking organised drainage; and * lakes created in volcanic remnants.

Australian Shelduck
The Australian shelduck (''Tadorna tadornoides''), also known as the chestnut-breasted shelduck or mountain duck, is a shelduck, a group of large goose-like ducks part of the bird family Anatidae. The genus name ''Tadorna'' comes from Celtic roots and means "pied waterfowl". They have a striking chestnut-coloured breast and black body. They are protected under the National Parks and Wildlife Act 1974. Taxonomy and naming William Jardine and Prideaux John Selby described the Australian shelduck in 1828. Description The males are mostly dark, with a chestnut breast. They have white neck collars and dark green heads. The females are similar, but they have white around the eyes and are smaller. Both males and females have chestnut and black wings with a green speculum, and show some white on their wings during flight. The downy young are white with a brown crown and brown stripes from crown to tail. Juvenile males are duller than the adults and also lack a white collar, while juv ...

Moult
In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle. In medieval times it was also known as "mewing" (from the French verb "muer", to moult), a term that lives on in the name of Britain's Royal Mews where the King's hawks used to be kept during moulting time before becoming horse stables after Tudor times. Moulting can involve shedding the epidermis (skin), pelage (hair, feathers, fur, wool), or other external layer. In some groups, other body parts may be shed, for example, the entire exoskeleton in arthropods, including the wings in some insects. Examples In birds In birds, moulting is the periodic replacement of feathers by shedding old feathers while producing new ones. Feathers are ...

Drought Refuge
A drought refuge is a site that provides permanent fresh water or moist conditions for plants and animals, acting as a refuge habitat when surrounding areas are affected by drought and allowing ecosystems and core species populations to survive until the drought breaks. Drought refuges are important for conserving ecosystems in places where the effects of climatic variability are exacerbated by human activities. Description Reliable drought refuges are characterised by the ability to retain sufficient water throughout the drought, having water quality good enough to maintain the life of the ecosystem that are not subject to physical disturbance and that have access to surrounding habitat, so that refugees can recolonise the main habitat when the drought ends. For fish and aquatic invertebrates a drought refuge may be an isolated permanent pool in a stream that ceases to flow and mostly dries up during a period of drought.Bond, N.R. (2007).

A Directory Of Important Wetlands In Australia
A Directory of Important Wetlands in Australia (DIWA) is a list of wetlands of national importance to Australia published by the governmental agency Environment Australia. Intended to augment the list of wetlands of international importance under the Ramsar Convention, it was formerly published in report form, but is now essentially an online publication. Wetlands that appear in the ''Directory'' are commonly referred to as "DIWA wetlands" or "Directory wetlands". Criteria for determining wetland importance Using criteria agreed in 1994, a wetland can be considered “nationally important” if it satisfies at least one of the following criteria: # It is a good example of a wetland type occurring within a biogeographic region in Australia. # It is a wetland which plays an important ecological or hydrological role in the natural functioning of a major wetland system/complex. # It is a wetland which is important as the habitat for animal taxa at a vulnerable stage in their life cycle ...

Bluebird K7
''Bluebird K7'' is a jet engined hydroplane which Britain's Donald Campbell set seven world water speed records between 1955 and 1967. ''K7'' was the first successful jet-powered hydroplane, and was considered revolutionary when launched in January 1955. Campbell and ''K7'' were responsible for adding almost to the water speed record, taking it from existing mark of to just over . Donald Campbell was killed in an accident with a much modified ''K7'', on 4 January 1967, whilst making a bid for his eighth water speed record, with his aim to raise the record to over on Coniston Water. Design Donald Campbell began his record-breaking career in 1949 following the death of his father, Sir Malcolm Campbell. Initially, he had been using his father's 1939-built Rolls-Royce 'R' type powered propeller-driven hydroplane '' Blue Bird K4'' for his attempts, but he met with little success and suffered a number of frustrating setbacks. In 1951, ''K4'', which had been modified to a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
