The Shoalhaven River is a perennial river that rises from the Southern Tablelands and flows into an open mature wave dominated barrier estuarynear Nowra on the South Coast of New South Wales, Australia.
A perennial stream or perennial river is a stream or river (channel) that has continuous flow in parts of its stream bed all year round during years of normal rainfall. "Perennial" streams are contrasted with "intermittent" streams which normally cease flowing for weeks or months each year, and with "ephemeral" channels that flow only for hours or days following rainfall. During unusually dry years, a normally perennial stream may cease flowing, becoming intermittent for days, weeks, or months depending on severity of the drought. The boundaries between perennial, intermittent, and ephemeral channels are not defined, and subject to a variety of identification methods adopted by local governments, academics, and others with a need to classify stream-flow permanence.
The Southern Tablelands is a geographic area of New South Wales, Australia, located south-west of Sydney and west of the Great Dividing Range.
In fluid dynamics, wind waves, or wind-generated waves, are surface waves that occur on the free surface of bodies of water. They result from the wind blowing over an area of fluid surface. Waves in the oceans can travel thousands of miles before reaching land. Wind waves on Earth range in size from small ripples, to waves over 100 ft (30 m) high.
The Shoalhaven River rises on the eastern side of the Great Dividing Range, below Euranbene Mountain, about 350 kilometres (220 mi) southwest of Sydney. The upper reaches of the river flow northwards through an upland pastoral district near the town of Braidwood. The river works its way down into a remote canyon east of Goulburn and emerges into the coastal lowlands at Nowra in the Shoalhaven district, where it is spanned by the historic Nowra Bridge. The river is joined by thirty-four tributaries, including the Mongarlowe, Corang, Endrick, and Kangaroo rivers, and descends 864 metres (2,835 ft) over its 327-kilometre (203 mi) course.
The Great Dividing Range, or the Eastern Highlands, is Australia's most substantial mountain range and the third longest land-based range in the world. It stretches more than 3,500 kilometres (2,175 mi) from Dauan Island off the northeastern tip of Queensland, running the entire length of the eastern coastline through New South Wales, then into Victoria and turning west, before finally fading into the central plain at the Grampians in western Victoria. The width of the range varies from about 160 km (100 mi) to over 300 km (190 mi). The Greater Blue Mountains Area, Gondwana Rainforests, and Wet Tropics of Queensland World Heritage Areas are located in the range.
Sydney is the state capital of New South Wales and the most populous city in Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Port Jackson and extends about 70 km (43.5 mi) on its periphery towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, 40 local government areas and 15 contiguous regions. Residents of the city are known as "Sydneysiders". As of June 2017, Sydney's estimated metropolitan population was 5,230,330 and is home to approximately 65% of the state's population.
Braidwood is a town in the Southern Tablelands of New South Wales, Australia, in Queanbeyan–Palerang Regional Council. It is located on the Kings Highway linking Canberra with Batemans Bay. It is approximately 200 kilometres south west of Sydney, 60 kilometres inland from the coast, and fifty-five from Canberra. Braidwood is a service town for the surrounding district which is based on sheep and cattle grazing, and forestry operations.
The estuary has two entrances, approximately 5 kilometres (3.1 mi) apart, that flow into the Shoalhaven Bight within the Tasman Sea of the South Pacific Ocean. The southern entrance is located at Crookhaven Heads and is permanently open. The Shoalhaven River flows south via Berrys Canal to Greenwell Point, where it is joined by the Crookhaven River and then flows east past Orient Point into the bight, north of Culburra. The Berrys Canal between the Shoalhaven and the Crookhaven was constructed in June 1822 by convicts overseen by Hamilton Hume under the direction of Alexander Berry to facilitate ship transport to the original European settlement located in the region. The construction of the canal formed Comerong Island. The canal was dug using own hand tools, and was the first land navigable canal in Australia. Berrys Canal remains one of two navigable canals in New South Wales, the other being the Alexandra Canal.
The Tasman Sea is a marginal sea of the South Pacific Ocean, situated between Australia and New Zealand. It measures about 2,000 kilometres (1,200 mi) across and about 2,800 kilometres (1,700 mi) from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, who was the first recorded European to encounter New Zealand and Tasmania. The British explorer Captain James Cook later extensively navigated the Tasman Sea in the 1770s as part of his first voyage of exploration.
In geography, a bight is a bend or curve in a coastline, river, or other geographical feature. It typically indicates a large, open bay, often only slightly receding. It is distinguished from a sound by being shallower. Traditionally, explorers defined a bight as a bay that could be sailed out of on a single tack in a square-rigged sailing vessel, regardless of the direction of the wind.
Hamilton Hume was an early explorer of the present-day Australian states of New South Wales and Victoria. In 1824, along with William Hovell, Hume participated in an expedition that first took an overland route from Sydney to Port Phillip. Along with Sturt in 1828, he was part of an expedition of the first Europeans to discover the Darling River.
The northern entrance is located south of Shoalhaven Heads, and is open intermittently, at times of peak flow and during flood events.
Tallowa Dam is the only major dam on the Shoalhaven, and is a part of the Shoalhaven Scheme. It impounds the river's lower reaches to form Lake Yarrunga and part of Sydney's water supply. Some water is pumped out of the lake and over the Southern Highlands into Lake Burragorang. Proposals for a much larger water storage at Welcome Reef on the upper Shoalhaven have been shelved.[ citation needed ]
Tallowa Dam, completed in 1976, is a concrete gravity dam with central overflow spillway, located on the Shoalhaven River, downstream from the river's confluence with the Kangaroo River. The dam wall of 325 cubic metres (11,500 cu ft) is 43 metres (141 ft) high and 528 metres (1,732 ft) in length. At 100% capacity, the dam wall holds back approximately 85,500 megalitres and creates the impounded reservoir of Lake Yarrunga that has a surface area of 831 hectares, drawn from a catchment area of 5,750 square kilometres (2,220 sq mi). The spillway has a discharge capacity of 27,600 cubic metres per second (970,000 cu ft/s).
The Shoalhaven Scheme is a dual-purpose water supply and hydro-electric power generation scheme located on the South Coast region of New South Wales, Australia.
Lake Burragorang is an Australian man-made water supply dammed reservoir.
The Shoalhaven River and its main tributary the Kangaroo River were once renowned as an Australian bass fishery. Unfortunately, Tallowa Dam has been a potent barrier to migratory native fish with estuarine/marine juvenile stages, blocking species including Australian bass from more than 80% of their former range in the Shoalhaven system. Recent stockings of hatchery-bred Bass in Lake Yarrunga are an attempt to remediate the situation.[ citation needed ] A fishway for Tallowa Dam was completed in August 2009. This fishway is designed to allow for the movement of bass and other native fish over the dam. Lake Yarrunga has also suffered the illegal introduction of highly damaging European carp, which are now present in high densities.
The Australian bass is a small to medium-sized, primarily freshwater species of fish found in coastal rivers and streams along the east coast of Australia. It is a member of the family Percichthyidae and the genus Macquaria. Australian bass is an important member of the native fish assemblages found in east coast river systems. It is a predatory native fish and an extremely popular angling species. The species was simply called perch in most coastal rivers where it was caught until the 1960s, when the name Australian bass started to gain popularity.
The common carp or European carp is a widespread freshwater fish of eutrophic waters in lakes and large rivers in Europe and Asia. The native wild populations are considered vulnerable to extinction by the International Union for Conservation of Nature (IUCN), but the species has also been domesticated and introduced into environments worldwide, and is often considered a destructive invasive species, being included in the list of the world's 100 worst invasive species. It gives its name to the carp family Cyprinidae.
The traditional custodians of the land surrounding the Shoalhaven River, in its lower reaches, are the Aboriginal peoples of the Yuin nation. In the land north of the river, the people from the Wodi Wodi clan are the traditional custodians; while south of the river, the Wandi Wandian clan are the traditional custodians.Some of the culturally important Aboriginal places in the Shoalhaven include Coolangatta Mountain, Bundarwa (Beecroft Headland), Cambewarra Mountain, Didthul or Pigeon House Mountain, Kangaroo Valley, Burrill Lake, and Murramarang Aboriginal Area and its environs.
The explorer and navigator George Bass found the entrance to the Shoalhaven River during his whaleboat voyage down the south coast of New South Wales in 1797. He gave the name Shoals Haven to the river (now known as the Crookhaven River) because of the shoals of mud and sand he found at the river mouth.
Approximately 20 kilometres (12 mi) west of Nowra are a series of properties along the banks of the Shoalhaven River that were a gift to the people of Australia from Arthur Boyd, his wife, Yvonne, and the Boyd Family. Entrusted to the Bundanon Trust, along with further gifts by Boyd, including copyright of all of his artwork, these properties provide an environment that promotes visual arts, writing, music and other performing arts, and the promotion of education and research in the arts.

Bendeela Pondage, completed in 1972, is an earth and rockfill embankment dam structure located on the Kangaroo River arm of Lake Yarrunga in New South Wales, Australia. It is located between Fitzroy Falls Dam and Tallowa Dam. The pondage, part of the Shoalhaven Scheme, functions as a buffer storage for out-of-balance flow between the two dams during hydro-electric power generation or water pumping at Kangaroo Valley and Bendeela pumping and power stations. The dam has no significant catchment but has been provided with a weir type spillway to protect the dam in the event of operational problems at the two pumping and power stations. The embankment is 15 metres (49 ft) high and 2,118 metres (6,949 ft) in length. At 100% capacity, the dam wall holds back approximately 1,200 megalitres.
Fitzroy Falls Dam in New South Wales, Australia, is part of the Shoalhaven Scheme, completed in 1974. It consists of four separate earth and rockfill embankments located on the Yarrunga Creek upstream of Fitzroy Falls and about 16 kilometres (9.9 mi) southeast of Moss Vale. The main embankment of 760 cubic metres (27,000 cu ft) is 14 metres (46 ft) high and 1,530 metres (5,020 ft) in length. At 100% capacity, the dam wall holds back approximately 9,950 megalitres of water, creating the impounded Fitzroy Falls Reservoir, which has a surface area of 522 hectares, drawn from a catchment area of 31 square kilometres (12 sq mi). The spillway has a discharge capacity of 516 cubic metres per second (18,200 cu ft/s).
