Cardross Lakes
The Cardross Lakes are an irrigation drainage basin system located approximately south-west of Mildura, in the Mallee region of Victoria, Australia.

Mallee (Victoria)
The Mallee covers the most northwesterly part of Victoria, bounded by the South Australian and New South Wales borders. Definitions of the south-eastern boundary vary, however, all are based on the historic Victorian distribution of mallee eucalypts. These trees dominate the surviving vegetation through most of Mallee, (except for swamps and areas along waterways, and very rare stands of ''casuarina''). Its biggest settlements are Mildura and Swan Hill. At the 2011 census, the four local government areas (LGAs) that are usually thought to define the district had a combined population of . The area of these same four LGAs is . There is an adjacent area also once covered with mallee scrub called "the Mallee" in South Australia, which is alternatively called the Murray Mallee. Geography and climate The Mallee is, for all practical purposes, completely flat and very low-lying: in fact, for long geological periods the whole region has been inundated by the ocean. Most of ...

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 metr ...

Artificial Lake
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the ...

Irrigation In Australia
Irrigation is a widespread practice required in many areas of Australia, the driest inhabited continent, to supplement low rainfall with water from other sources to assist in growing crops and pasture. Overuse or poor management of irrigation is held responsible by some for environmental problems such as soil salinity and loss of habitat for native flora and fauna. Irrigation differs from dryland farming (farming relying on rainfall) in Australia in its level of intensity and production. Common crops produced using irrigation include rice, cotton, canola, sugar, various fruits and other tree crops and pasture, hay and grain for use in beef and dairy production. Surface irrigation is the most common irrigation method in Australia, with drip and center pivot also utilised. All rights to use and control water are vested in the state, which issues conditional entitlements for water use. The first large-scale irrigation schemes in Australia were introduced during the 1880s, parti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Mogurnda Adspersa
''Mogurnda adspersa'' (commonly known as the southern purple-spotted gudgeon) is a species of endangered gudgeon that is endemic to south-eastern mainland Australia (the states of South Australia, New South Wales and Victoria and Queensland). The fish is brown, although the shade becomes lighter near its abdomen. Spots of various colours occur on its sides. After a dramatic population decline in the late 20th century, the fish was thought to be locally extinct in several areas, but was rediscovered both in South Australia and Victoria in the 21st century. Various state governments, the (Commonwealth Government) Murray-Darling Basin Authority, and various volunteer organisations have been taking measures to increase the fish's numbers. Description ''Mogurnda adspersa'' is countershaded dark brown on top, with its colour becoming progressively lighter on the sides and underside, where it is light brown or cream. The fish has three red bars on each cheek, and red, purple, black, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Murray Hardyhead
The Murray hardyhead (''Craterocephalus fluviatilis'') is a species of fish in the family Atherinidae endemic to inland parts of southeastern Australia. The fish is an omnivore, feeding on small crustaceans, aquatic insects and algae Algae ( , ; : alga ) are any of a large and diverse group of photosynthetic, eukaryotic organisms. The name is an informal term for a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from .... Conservation The fish was once widespread and abundant in the Murray and Murrumbidgee River systems in southern NSW and northern Victoria. However, they have suffered a serious population decline and now seem to be limited to a few sites, mainly in northern Victoria. There are very few recent records of Murray hardyheads from NSW. The main threat to remaining populations is increasing salinity and lack of water. Murray hardyheads are now listed as an endangered species in NSW and threatened in ...

Lakes Of Victoria (state)
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
