Historical records show that the channel out to sea moves along the sand dunes over time. At times of greater river flow and rough seas, the two bodies of water would erode the sand dunes to create a new channel leaving the old one to silt and disappear. The mouth of

Coorong and Lakes Alexandrina and Albert Wetland Lake Alexandrina is a coastal freshwater lake located between the Fleurieu and Kangaroo Island and Murray and Mallee regions of South Australia , about 100 kilometres (62 mi) south-east of Adelaide .

George "Chinese" Morrison , then aged 18, navigated the river by canoe from Wodonga to its mouth, in 65 days, completing the 1,555-mile (2,503 km) journey in January 1881. Shipping cannot enter the Murray from the sea because it does not have an estuary . However, in the 19th century the river supported a substantial commercial trade using shallow-draft paddle steamers ,

The Murray River has been a significant barrier to land-based travel and trade. Many of the ports for transport of goods along the Murray have also developed as places to cross the river, either by bridge or ferry. The first bridge to cross the Murray, which was built in 1869, is in

From the Pleistocene about 2.5 million years ago,

The Murray was plagued by "snags", fallen trees submerged in the water, and considerable efforts were made to clear the river of these threats to shipping by using barges equipped with steam-driven winches . In recent times, efforts have been made to restore many of these snags by placing dead gum trees back into

They are the Goolwa Barrage, with a length of 632 metres (2,073 ft); Mundoo Channel Barragel 800 metres (2,600 ft); Boundary Creek Barragel 243 metres (797 ft); Ewe Island Barrage, 853 metres (2,799 ft); and Tauwitchere Barrage, 3.6 kilometres (2.2 mi). These dams inverted

The unreliable levels made it impossible for boats to compete with the rail and later road transport . However, the river still carries pleasure boats along its entire length. Today, most traffic on the river is recreational. Small private boats are used for water skiing and fishing. Houseboats are common, both commercial for hire and privately owned. There are

Eager to rectify his failure to catch his prey, the hunter and his two wives (sometimes the escaped sibling wives of Waku and Kanu) hurried on, and took positions high on the cliff on which Tailem Bend now stands. They sprung an ambush on Pondi only to fail again. Ngurunderi set off in pursuit again but lost his prey as Pondi dived into Lake Alexandrina. Ngurunderi and

Its tributaries include five of the next six longest rivers of Australia (the Murrumbidgee , Darling , Lachlan , Warrego and Paroo Rivers ). Together with that of the Murray, the catchments of these rivers form the Murray–Darling basin , which covers about one-seventh the area of Australia. It

The Murray also receives water from the complex dam and pipeline system of the Snowy Mountains Scheme . An additional reservoir was proposed in the 1960s at Chowilla Dam , which was to have been built in South Australia and would have flooded land mostly in Victoria and New South Wales. It was cancelled in favour of building Dartmouth Dam due to costs and concerns relating to increased salinity. From 1935 to 1940

But Pondi was a wily prey and carved a weaving path, carving out the river's various tributaries.

In a 1980 judgement, the High Court of Australia ruled on the question as to which state had jurisdiction in the unlawful death of a man who was fishing by the river's edge on the Victorian side of the river. This boundary definition can be ambiguous, since the river changes its course over time, and some of

The lake is shallow and contains a number of islands near the southern end. Loveday Bay is an inlet located at the south-east of Lake Alexandrina, adjacent to Tauwitchere Channel. Lake Alexandrina is connected by a narrow channel to

The Murray rises in the Australian Alps , draining the western side of Australia's highest mountains, then meanders northwest across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows into South Australia . From an east–west direction it turns south at Morgan for its final 315 km (196 mi), reaching

Aboriginal people having an association with the lake were reported as knowing it by such names as Mungkuli, Parnka and Kayinga. English settlers named the lake after Princess Alexandrina , niece and successor of King William IV of Great Britain and Ireland. When

West of this sector, the Murray is entirely within

#17327718071111650-517: The river red gum . The health of the Murray has declined significantly since European settlement, particularly through regulation of its flows. Extreme droughts between 2000 and 2007 put significant stress on river red gum forests, leading to mounting concern over their long-term survival. The Murray has also flooded on occasion. The most significant was the flood of 1956 : lasting for up to six months, it inundated many towns on its lower reaches in South Australia. Between 2.5 and 0.5 million years ago,
1725-467: The Cadell Fault. About 25,000 years ago, displacement occurred along this fault, raising its eastern edge, which runs north–south, 8 to 12 m (26 to 39 ft) above the floodplain. This created a complex series of events. A section of the original Murray River channel immediately behind the fault was rendered abandoned (it exists today as an empty channel known as Green Gully).

The mouth is an opening in the coastal dune system which separates the river system from the ocean and which extends from near Goolwa in a south-easterly direction along the continental coastline for about 145 kilometres (90 miles). The mouth divides

The lake drained less than a million years ago, creating the current course.

At its maximum extent, Lake Bungunnia covered 33,000 km (12,741 sq mi), extending to near the Menindee Lakes in the north and to near Boundary Bend in the south. The draining of Lake Bungunnia occurred approximately 600,000 years ago. Deep clays deposited by

The Murray has not had enough flow power to naturally enlarge The Barmah Choke and The Narrows to increase the amount of water they can carry.

As of 2010 , the Murray River system received 58 per cent of its natural flow; the figure varies considerably.

Thus the displacement of the Cadell Fault 25,000 BP led directly to the formation of the famous Barmah River Red Gum Forests.

The Murray carries only a small fraction of the water of comparably sized rivers in other parts of the world, and with great annual variability of its flow.

These were originally proposed to support navigation even in times of low water, but riverborne transport was already declining due to improved highway and railway systems.

In 2006, the Government of South Australia released a plan to investigate the construction of controversial Wellington Weir . Lock 1 was completed near Blanchetown in 1922.

Considerably higher rainfall would have been required to keep such a lake full; the draining of Lake Bungunnia appears to have marked the end of a wet phase in the history of the Murray–Darling Basin and the onset of widespread arid conditions similar to today.

There are widespread concerns that the river will be unusably salty in the medium to long term – a serious problem given that the Murray supplies 40 per cent of the water supply for Adelaide . Efforts to alleviate the problems have proceeded but disagreement between various groups has hampered progress. Introduced fish species such as carp , gambusia , weather loach , redfin perch , brown trout , and rainbow trout have also had serious negative effects on native fish. The most pernicious are carp, which have contributed to environmental degradation of
