The Warragamba River is a river in the east of the Australian state of New South Wales .

It is a tributary of the Nepean River , a source of the Hawkesbury River . The Warragamba dam was built on it, on which the river to Lake Burragorang , the largest reservoir for water supply of Sydney, is dammed.

Before the dam was built, the Warragamba River was formed at the confluence of the Coxs River , Nattai River and Wollondilly River in the Burragorang Valley . Downstream, the river passed a gorge that was between 300 m and 600 m wide and 100 m deep. This configuration made it possible to build a narrow but quite high dam, which made it possible to retain a large amount of water in the gorge. Today, the Burragorang Valley and much of the course of the river are covered by Lake Burragorang, and the remainder of the river flows from the lower end of the Warragamba Dam only three and a half kilometers to its confluence with the Nepean River.
