Lake Argyle is Western Australia's largest and Australia's second largest〔(【引用サイトリンク】title=Largest Waterbodies )〕 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.〔(【引用サイトリンク】title=Search for a Nationally Important Wetland )〕 as it is the largest lake in northern Australia and an excellent example of a man-made lake. Additionally Lake Argyle, along with Lake Kununurra, are recognised as a Ramsar protected wetlands and were listed in 1990 as Australian Site Number 32.〔(【引用サイトリンク】title=Australian Ramsar Sites - Lake Argyle and Kununurra )〕 ==History and construction== The construction of the Ord River Dam was completed in 1971 by the American 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 the amount of water stored. The lake was named after the property it partly submerged, Argyle Downs.〔 In 1996, the spillway wall was raised by , which doubled the dam's capacity. Sediment flowing into the dam caused concerns in the mid-1990s that the dam's capacity could be dramatically reduced. By 2006 continual regeneration of the upper Ord catchment appeared to have reduced the amount of sediment inflow. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lake Argyle」の詳細全文を読む スポンサード リンク
