Course and features

The Cataract River rises on the western slopes of the Illawarra escarpment, west of Mount Pleasant, and flows generally north northwest, impounded within Lake Cataract, before reaching its confluence with the Nepean River at Douglas Park. The river descends 215 metres (705 ft) over its 23-kilometre (14 mi) course.[2]

The river is a source of water for the Sydney region. Water is collected by the dams, weirs and aqueducts of the Upper Nepean Scheme.
