The Woronora River is a perennial river of the Sydney Basin, located in the Sutherland Shire local government area of Greater Metropolitan Sydney, approximately 22 kilometres (14 mi) south of the Sydney central business district, in New South Wales, Australia.
Location and features
The Woronora River rises on the northwestern slopes of the Illawarra escarpment and has its origin from Waratah Rivulet, near Darkes Forest, and flows generally north for approximately 36 kilometres (22 mi), joined by three minor tributaries, before reaching its confluence with the Georges River, between Como and Illawong. The total catchment area of the river is approximately 174 square kilometres (67 sq mi) and the area is generally administered by the Sydney Catchment Authority in its upper reaches and the Sutherland Shire Council in its lower reaches.[3] Much of the course of the river is through the Dharawal State Conservation Area, Heathcote National Park and the Royal National Park as it descends 354 metres (1,161 ft) from source to mouth.[2]
The river is impounded by the Woronora Dam, opened in 1941. The 71,790-megalitre (2,535×106 cu ft) impoundment is Lake Woronora, formed to augment water supply for southern Sydney and the northern Illawarra region.[2]
The Woronora River is traversed by high level and low level road bridges and a footbridge in the suburb of Woronora. A road bridge on Heathcote Road, linking Heathcote and Holsworthy also provides a crossing over the river. At the area known as "The Needles", near Woronora Road in Engadine, a footbridge links the suburb to Barden Ridge.
Etymology
In the Australian Aboriginal Dharug language the river draws its name, meaning "black rocks".[1]
