Map of Lake Illawarra, New South Wales, Australia
The lake environment is administered by the Lake Illawarra Authority, a New South Wales statutory authority established pursuant to the Lake Illawarra Authority Act 1987 (NSW) with the aim of transforming the degraded waters and foreshores of Lake Illawarra into an attractive recreational and tourist resource.
Location and features
Located south of the city of Wollongong, north of the city of Shellharbour, and 5 kilometres (3.1 mi) northeast of Dapto, Lake Illawarra receives runoff from the Illawarra escarpment through Macquarie Rivulet and Mullet Creek, drawing from a catchment area of 238 square kilometres (92 sq mi). With an average depth of 2.1 metres (6 ft 11 in), the relatively shallow lake, brought about because of infilling by sand which has been eroded from the surrounding catchments, covers a surface area of 35.8 square kilometres (13.8 sq mi). At an elevation of 0.3 metres (1 ft 0 in) AHD , the maximum volume of water held in the lake is 74,275 megalitres (2,623.0×106 cu ft).
The narrow tidal entrance to the Tasman Sea of the South Pacific Ocean is located at Windang.
Located on the western shore of Lake Illawarra at Yallah is the natural gas-powered Tallawarra Power Station. The power station draws water from the lake for cooling purposes, and returns water to the lake via an onsite water management system that ensures water quality is maintained at levels above the catchment average.
The lake's location within the sprawling Wollongong urban area means that Lake Illawarra is vulnerable to pollution and urban run-off.
Recreation
Lake Illawarra is popular for recreational fishing, prawning and sailing. On 12 January 2009, it is suspected a man was bitten by a bull shark whilst snorkelling at Windang, near the mouth of Lake Illawarra.
Birds found at the lake include pelicans, cormorants, musk ducks, hoary-headed grebes, black swans, black ducks, grey teal ducks, herons, ibises and spoonbills.
History
The traditional custodians of the land surrounding what is now known as Lake Illawarra are the Aboriginal Tharawal and Wadi Wadi peoples. Lake Illawarra was a valuable source of food and spirituality. Burial sites and middens (shell and camp rubbish heaps) discovered at Windang and surrounding areas indicate that the Wadi Wadi used the area extensively and performed various corroborees and ceremonies in the area. The name Illawarra is derived from various adaptions of the Aboriginal Tharawal language words of elouera, eloura, or allowrie; illa, wurra, or warra mean generally a pleasant place near the sea, or high place near the sea, or white clay mountain.
Matthew Flinders and George Bass called the lake Tom Thumb's Lagoon on Flinders' chart, named after their little boat the Tom Thumb, when they were there in March 1796.‹See TfD›
In Lake Illawarra: an ongoing history, Joseph Davis provides a wide-ranging environmental and historical biography of the lake and its foreshores. The book also contains many images and photographs depicting the lake. Davis edited John Brown of Brownsville: his manuscripts, letterbook and the records of Dapto Show Society 1857-1904 that deals with the man who did most to protect the vegetation of the lake islands, and he authored Gooseberry & Hooka: the island reserves of Lake Illawarra 1829-1947, the latter examining the records of John Brown and others and deals with the history of these two islands and how they survived to become nature refuges rather than recreation reserves.
