Warragamba River
The Warragamba River is a tributary of the Nepean River, and hence of the Hawkesbury River, in New South Wales, Australia. It is best known for being the location of the Warragamba Dam and Lake Burragorang, which form a major part of the water supply to the Sydney region.[1]
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 300 metres (980 ft) to 600 metres (2,000 ft), and was 100 metres (330 ft) 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 3.5 kilometres (2.2 mi) north-east from the Warragamba Dam to its confluence with the Nepean River.[1][2]
