Islands Of Lake Argyle
The Lake Argyle Islands are a large group of islands in Lake Argyle, created by the Ord River Dam on the Ord River in the Kimberley region of Western Australia. There are nearly 70 islands with official names, including most of the larger islands, as well as some small rocky outcrops. Formation The islands are former elevated points and ranges found on what used to be a section of Argyle Cattle Station, prior to the damming of the Ord River in 1971. As the lake filled, the lower grasslands became submerged while higher places along ranges became newly formed islands. The dam has never, and highly unlikely to be dry, thus ensuring most islands are permanent. As the lake level often changes islands can grow, shrink, disappear and reappear according to water levels. Some islands have rocky or sandy beaches and quite a range of flora and fauna, while others are swampy/fully rock and are quite barren.

Lake Argyle
Lake Argyle is Western Australia's largest and Australia's second largest freshwater man-made reservoir by volume. The reservoir is part of the Ord River Irrigation Scheme and is located near the East Kimberley town of Kununurra. The lake flooded large parts of the Shire of Wyndham-East Kimberley on the Kimberley Plateau about inland from the Joseph Bonaparte Gulf, close to the border with the Northern Territory. The primary inflow is the Ord River, while the Bow River and many other smaller creeks also flow into the dam. The lake is a DIWA-listed wetland. Lake Argyle and Lake Kununurra were listed in 1990 as Ramsar Convention protected wetlands. History and construction The construction of the Ord River Dam was completed in 1971 by Dravo Corporation. The dam was officially opened the following year. The dam wall is long, and high. The earth-fill only dam wall at Lake Argyle is the most efficient dam in Australia in terms of the ratio of the size of the dam wall to th ...

Ord River
The Ord River is a river in the Kimberley region of Western Australia. The river's catchment covers . The lower Ord River and the conjunction with Cambridge Gulf create the most northern estuarine environment in Western Australia. The Ord River Irrigation Scheme was built in stages during the 20th century. Australia's largest artificial lake by volume, Lake Argyle, was completed in 1972. It has not been economically successful; $1.45 billion has been spent on the Ord Irrigation Scheme for a return of 17 cents on the dollar, and only 260 jobs created. The lower reaches of the river support an important wetland area known as the Ord River Floodplain, a protected area that contains numerous mangrove forests, lagoons, creeks, flats and extensive floodplains. The traditional owners are the Miriwoong and Gajerrong peoples who have inhabited the area for thousands of years and know the Ord River as . In a letter to the Surveyor General, dated 12 October 1959, Louise Gardine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Island
A lake island is any landmass within a lake. It is a type of inland island. Lake islands may form a lake archipelago. Formation Lake islands may form in numerous ways. They may occur through a build-up of sedimentation as shoals, and become true islands through changes in the level of the lake. They may have been originally part of the lake's shore, and been separated from it by erosion, or they may have been left as pinnacles when the lake formed through a raising in the level of a river or other waterway (either naturally, or artificially through the damming of a river or lake). On creation of a glacial lake a moraine can form an island. They may also have formed through earthquake, meteor, or volcanic activity. In the latter case, crater or caldera islands exist, with new volcanic prominences in lakes formed in the craters of larger volcanoes. Other lake islands include ephemeral beds of floating vegetation, and islands artificially formed by human activity. Volcanic crat ...

Islands Of The Kimberley (Western Australia)
The Islands of the Kimberley are a group of over 2,500 islands lying off the coast of the Kimberley region of Western Australia. The islands extend from the Western Australia–Northern Territory border in the east to just north of Broome in the west.
