The Darling River is the longest river on the continent of Australia at 2,844 kilometers (including headwaters) .

It flows into the Murray River . It has a very irregular water flow averaging 102 m³ / s at Menindee .

The river is referred to as the Darling River for only 1570 kilometers . The successive sections of the Culgoa River , Condamine River and Balonne River of the right - smaller but longer - source river are added to the total length of 2,844 kilometers . Together with the 828-kilometer stretch of river after it flows into the Murray River, this results in a river system of 3672 kilometers in length.

Since 2005 there have been long periods of drought, which lead to the river falling dry in places, especially in the lower reaches. The river's water is used for irrigation of agricultural areas and as drinking water for humans and cattle. Wild animals are also dependent on the river water. The Murray-Darling Basin Authority , which was created in 2007, aims to regulate the equitable use of water in the Murray-Darling Basin by the states of Queensland , New South Wales , Australian Capital Territory , Victoria and South Australia .

geography

River course

Darling and Murray originate on the western slopes of the Great mountains vagina ( Great Dividing Range ) and flow into weak turns with very low gradient (6-14 centimeters per kilometer) by grasslands to the west and south. The Darling is created by the confluence of the Culgoa River (right) and Barwon River (left, more watery) near Bourke . The right, longer source river is called the Condamine River , later the Balonne River , in the upper reaches and then merges into the Culgoa.

Periodically recurring droughts can cause the darling to turn into a chain of pools. In the years between 1885 and 1960 alone, the river at Menindee fell dry 48 times; 1902/03 even for 364 days. If there is flooding, huge areas are flooded. The floods then leave their bed despite up to twelve meters high embankments and spread over flat terrain for up to 80 kilometers. Nowadays the salinization of the river is a major problem, for which dry periods and erosion caused by clearing are the main causes.

In the Menindee Lakes near Menindee , flood peaks can be temporarily stored and gradually given to agriculture to irrigate the fields. The lakes serve as a drinking water reservoir for the town of Broken Hill , 120 kilometers away . Treaties between the states of New South Wales, Victoria and South Australia regulate how much water is fed back into the river.

At Wentworth the Darling flows into the Murray , which flows to the Indian Ocean . The runoff here is much lower than at Menindee, mainly due to water drainage, and averages only around 47.56 m³ / s (at Burtundy).

South of Menindee, the Darling used to run further west in a river bed. Since the completion of the Menindee Lakes , water has been channeled into the former Great Darling Anabranch river to provide water for the area's ranchers. In the future, the farmers will be supplied with a pipeline, which will allow the Anabranch to be converted back into a natural dry valley ecosystem. The Great Darling Anabranch flows into the Murray around a dozen kilometers west of Wentworth.

history

From 1815 the areas on the headwaters of the Darling were gradually settled. In 1828, Ralph Darling , Governor of New South Wales, commissioned the explorer Charles Sturt , accompanied by his old companion, Hamilton Hume , to explore the Macquarie River . During this expedition they discovered the Darling River, which was named after the client. In 1835 Thomas Mitchell embarked on an expedition on which he was the first to explore the entire course of the Darling, thus proving its confluence with the Murray, which Sturt had previously suspected.

Darling and Murray were important transportation routes from the second half of the 19th century. Up to 240 paddle steamers were on the two rivers and their tributaries. The ships with shallow drafts mainly transport wool and wheat to the coast and supply the settlers with goods. From the turn of the century, the importance of rivers as transport routes decreased rapidly after major droughts made transport difficult and the railroad became more and more popular.

In the 2010s, the river on the lower reaches of the river dried up completely, and millions of fish died . The population on the lower reaches around Menindee accuses the Murray-Darling Basin Authority, which should regulate a compatible use of water in the various states, of failure. It is complained that in the headwaters in Queensland too much water would be withdrawn for cotton cultivation and that not enough water would reach the lower reaches. The government justifies the water shortage primarily through long periods of drought.
