Lake Menindee
The Menindee Lakes is a system of 9 large, but relatively shallow lakes, located in south-west New South Wales on the Darling (Barka) River, about 200 km upstream of the Darling River's junction with the River Murray. The Darling River is fed by nine major tributary river systems flowing from south-east Queensland and north and central NSW. The town of Menindee is close to the lakes and the nearest city is Broken Hill. There are 4 main lakes in the system: * Lake Wetherell * Lake Pamamaroo * Lake Menindee (the largest lake) * Lake Cawndilla. The lakes rely on replenishment, when water flows over the banks of the Darling (Barka) River. The NSW Government modified the lakes (completed 1968) to improve their storage capacity for farming, recreation, mining and urban water supply and to help manage floods in the Darling River. In the 1960s, governments decided to use some of the lakes as water storages, building a large weir (Main Weir) to divert water into lakes Pamamaroo, ...

Far West (New South Wales)
The Far West region of New South Wales, Australia refers generally to the western part of the state, which is too dry to support wheat or other crops or intensive pastoral endeavours. It is west of the North West Slopes, Central West and the Riverina. It is an area with limited rainfall, and the only major rivers found in it are the Darling River and the Murray River (on its southern edge), which originate in the Great Dividing Range to the east. The region corresponds to the combination of the Australian Bureau of Meteorology's forecast areas of ''Upper Western'' and ''Lower Western''. It also corresponds to the Western Division established under the New South Wales ''Western Lands Act 1901''. Its only city is Broken Hill, and other significant towns are Bourke, Brewarrina, Cobar, Ivanhoe and Wentworth. Ninety-five per cent of the region is uncleared. The major industries are mining and extensive pasturing. During good seasons in the 1870s and 1880s, large sheep stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...

Golden Perch
The golden perch (''Macquaria ambigua'') is a medium-sized, yellow or gold-coloured species of Australian freshwater fish found primarily in the Murray-Darling River system, though a subspecies is found in the Lake Eyre-Cooper Creek system, and another subspecies, suspected to be ancestral to all other populations, is found in the Fitzroy River system in Queensland. Other common names for golden perch are "goldens", “yellowbelly” and "callop", the last generally used only in South Australia. Golden perch are not a true perch, which belongs to the genus ''Perca'' from the family Percidae, but a member of the Percichthyidae (temperate perch) family. This relatively widespread and widely stocked species is an important angling sport fish in Australia. Description Golden perch are medium-sized fish, commonly 30–40 cm and 1–2 kg in rivers. Fish from rivers are smaller and somewhat streamlined — fish in man-made impoundments are much deeper-bodied and show much ...

Bidyanus Bidyanus
The silver perch (''Bidyanus bidyanus'') is a medium-sized freshwater fish of the family Terapontidae endemic to the Murray-Darling river system in south-eastern Australia. Taxonomy The silver perch's scientific name comes from an aboriginal name for the species – ''bidyan'' – recorded by Major Mitchell on the Barwon River on his 1832 expedition. (Mitchell's original scientific name for the species was ''Cernua Bidyana''.) Silver perch are not a "true" perch of the genus ''Perca'', but are instead a member of Terapontidae or 'grunter' family. They are the largest member of the Terapontidae, capable of growing in excess of and close to , but today wild river specimens are typically and . The silver perch is the only major representative of the family Terapontidae in the southern Murray-Darling system, compared to northern tropical systems where terapontid species are common. Another small terapontid, the spangled perch (''Leiopotherapon unicolor''), does occur sporadic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herring
Herring are forage fish, mostly belonging to the family of Clupeidae. Herring often move in large schools around fishing banks and near the coast, found particularly in shallow, temperate waters of the North Pacific and North Atlantic Oceans, including the Baltic Sea, as well as off the west coast of South America. Three species of ''Clupea'' (the type genus of the herring family Clupeidae) are recognised, and comprise about 90% of all herrings captured in fisheries. The most abundant of these species is the Atlantic herring, which comprises over half of all herring capture. Fish called herring are also found in the Arabian Sea, Indian Ocean, and Bay of Bengal. Herring played an important role in the history of marine fisheries in Europe, and early in the 20th century, their study was fundamental to the development of fisheries science. These oily fish also have a long history as an important food fish, and are often salted, smoked, or pickled. Herring are also known as "sil ...

Paakantyi
The Paakantyi, or Barkindji or Barkandji, are an Australian Aboriginal tribal group of the Darling River (known to them as the Baaka) basin in Far West New South Wales, Australia. Name The ethnonym Paakantyi means "River people", formed from ''paaka'' river and the suffix ''-ntyi'', meaning "belonging to", thus "belonging to the river". They refer to themselves as ''wimpatjas''. The name ''Paakantyi'' therefore simply means the River People. Language Traditionally they speak the Paakantyi language of the Pama–Nyungan family, and one of the three major Aboriginal languages for the people of present-day Broken Hill region. The major work on the Paakantyi language has been that of the late linguist Luise Hercus. Country The Paakantyi dwelt along the Darling River, from Wilcannia downstream almost to Avoca. Inland from either side of the Darling, their territory extended to a distance of roughly 20–30 miles. According to Norman Tindale, they inhabited an area of some . ...

Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a tel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Speculation
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] |
Ecological Resilience
In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil, and the introduction of exotic plant or animal species. Disturbances of sufficient magnitude or duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates. When such thresholds are associated with a critical or bifurcation point, these regime shifts may also be referred to as critical transitions. Human activities that adversely affect ecological resilience such as reduction of biodiversity, exploitation of natural resources, pollution, land use, and anthropogenic climate change are incre ...

Waterbird
A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water. In some definitions, the term ''water bird'' is especially applied to birds in freshwater ecosystems, although others make no distinction from seabirds that inhabit marine environments. Some water birds (e.g. wading birds) are more terrestrial while others (e.g. waterfowls) are more aquatic, and their adaptations will vary depending on their environment. These adaptations include webbed feet, beaks, and legs adapted to feed in the water, and the ability to dive from the surface or the air to catch prey in water. The term ''aquatic bird'' is sometimes also used in this context. A related term that has a narrower meaning is waterfowl. Some piscivorous birds of prey, such as ospreys and sea eagles, hunt aquatic prey but do not stay in water for long and lives predominantly over dry land, and are not considered water birds. The term waterbird is also used in the context of conservation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
