The Shoalhaven River is a river in the southeast of the Australian state of New South Wales .
It rises in the southern plateau of New South Wales and flows into the Tasman Sea at Nowra on the coast of New South Wales .
history
The explorer George Bass found the mouth of the Shoalhaven River in 1797 on a trip in his whaling boat down the New South Wales coast. He named the river Shoals Haven because of the muddy and sandy shoals he found in the mouth. Today this estuary is called the Crookhaven River .
geography
The Shoalhaven River rises on the eastern slopes of the Great Dividing Range about 350 km south of Sydney . In the upper reaches, it flows north through pastureland in the highlands near Braidwood . East of Goulburn , the river enters Morton National Park and turns its course to the east, where it has carved a narrow, inaccessible gorge into the plateau. At Nowra in the Local Government Area Shoalhaven City, it pours into the coastal lowlands. There the historic Nowra Bridge spans it .
Berry Canal
The river's estuary has two entrances, the southern one at Crookhaven Heads , which is always open, and the northern one at Shoalhaven Heads , which can only be passed at high tide. The two entrances are 5 km apart and about 150 km south of Sydney.
A short canal between the Shoalhaven River and the Crookhaven River was built in June 1882 by a group of convicts overseen by Hamilton Hume , under the direction of Alexander Berry , to facilitate the transport of goods to the European settlement there, Coolangatta Estate . Comorong Island was created through the construction of the canal . The canal was built using simple tools and was the first navigable artificial canal in Australia. To date, only one more navigable canal has been added in New South Wales, the Alexandra Canal near Sydney.
Use for water supply
The Lake Yarrunga defined by the Tullowa Dam was dammed, is the only major reservoir on the Shoalhaven River and part of the Shoalhaven system . It lies on the lower reaches and serves to supply drinking water to the greater Sydney area. Some of the water from the lake is pumped across the highlands into Lake Burragorang . Plans for a much larger reservoir at Welcome Reef on the upper reaches of the river have been abandoned.
environment
The Shoalhaven River and its main tributary, the Kangaroo River , were once known as good fishing waters for the Australian perch . Unfortunately, the Tullowa Dam presents an insurmountable barrier to migratory fish that spend their youth in the sea or an estuary, such as the Australian perch. The dam prevents them from accessing more than 80% of their previous habitat in the Shoalhaven River system. The release of farmed perch in Lake Yarrunga in November 2008 was an attempt to improve this situation. In August 2009 a fish ladder was installed at the Tullowa Dam. Lake Yarrunga has also suffered from the illegal use of very harmful, exotic carp , which are found there in very large numbers today.
River crossings
The following roads and modes of transport cross the Shoalhaven River (ordered downstream):
- The Warri Bridge on the Kings Highway spans the river at Braidwood. At this point a bridge was opened for the first time on September 23, 1874 and was later replaced by the current bridge.
- Steward's Crossing is a ford along the Steward's Crossing Road .
- Oallen Crossing is a single lane wooden bridge on Oallen Ford Road near Nerriga that was built in 1936.
- The Nowra Bridge spans the river on the Princes Highway between Bomaderry and Nowra.
- The Comorong Island Ferry brings passengers and cars to Comerong Island in the estuary.
