The Warragamba River, a river that is part of the Hawkesbury-Nepean catchment, is located in the Macarthur region of New South Wales, Australia. ==Course and features== Formed through the confluence of the Coxs River and two minor tributaries, Warragamba River rises within Lake Burragorang and is the river on which Warragamba Dam is established, creating a large reservoir with total capacity of , that forms a major part of the water supply to greater metropolitan Sydney. The river descends , the majority of which is over the dam spillway, and then flows north into the Nepean River, north of the village of Warragamba, a course of approximately .〔 Prior to the creation of Lake Burragorang, the Warragamba River would have been formed by the confluences of the Coxs, Nattai, and Wollondilly rivers in the Burragorang Valley. Downstream, the river flowed through a gorge that varied in width from to , and was in depth. It was this configuration which allowed a relatively short but high dam wall in the gorge to impound a large quantity of water. Today, the Burragorang Valley and most of the Warragamba River is submerged beneath the lake, and the remaining section of the river flows only the north-east from the Warragamba Dam spillway to its confluence with the Nepean River.〔 The area surrounding Warragamba River is managed by Sydney Catchment Authority under the that defines special zones and places restrictions and controls on land use, development and access in order to safeguard potable water. 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「Warragamba River」の詳細全文を読む スポンサード リンク
