Hunter River (New South Wales)

The Hunter River (Wonnarua: Coquun) is a major river in New South Wales, Australia. The Hunter River rises in the Liverpool Range and flows generally south and then east, reaching the Tasman Sea at Newcastle, the second largest city in New South Wales and a major harbour port. Its lower reaches form an open and trained mature wave dominated barrier estuary.[5]

The Hunter River rises on the western slopes of Mount Royal Range, part of the Liverpool Range, within Barrington Tops National Park, east of Murrurundi, and flows generally northwest and then southwest before being impounded by Lake Glenbawn; then flowing southwest and then east southeast before reaching its mouth of the Tasman Sea,[1] in Newcastle between Nobbys Head and Stockton. The river is joined by ten tributaries upstream of Lake Glenbawn; and a further thirty-one tributaries downstream of the reservoir. The main tributaries are the Pages, Goulburn, Williams and the Paterson rivers and the Moonan, Stewarts and Wollombi brooks. East of Hexham, the river splits into two main channels, separated by the Ramsar-protected Kooragang Wetlands that feeds Milham Ponds, Wader Pond, Swan Pond and a series of smaller wetland pondages. The southern arm of the river also creates Hexham Island, while the northern creates Smiths Island and flows in Fullerton Cove. The two channels converge at Walsh Point, reaching confluence with Throsby Creek adjacent to the Newcastle central business district, before reaching the river mouth. The Hunter River descends 1,397 m (4,583 ft) over its 468 km (291 mi) course from the high upper reaches, through the Hunter Valley, and out to sea.[3]

The Hunter River is subject to substantial flooding, which Glenbawn Dam, near Scone, was constructed to ameliorate. Major floods have occurred on the Hunter including the flood of 1955 that caused devastation to townships along the river, especially Maitland. Severe flooding again occurred in June 2007 and again in 2015.

Towns along the Hunter River, from upstream to downstream, include Aberdeen, Muswellbrook, Denman, Jerrys Plains, Singleton, Maitland, Morpeth, and Raymond Terrace.

At Hexham, the river is transversed by the Pacific Highway; while at Singleton and again at Aberdeen, the river is crossed by the New England Highway; and the Golden Highway crosses the river to the north and to the southeast of Denman.
