Darling and Paroo Rivers in New South Wales, Australia30.7S 144.4E
The thick green and tan line crossing this image diagonally from northeast to southwest is a section of the Darling River. It is the fourth longest river in Australia, measuring 1,472 kilometres (915 mi) from its source in northern New South Wales to its confluence with the Murray River at Wentworth, New South Wales.
Including its longest contiguous tributaries it is 2,844 km (1,767 mi) long, making it the longest river system in Australia. One of its major tributaries, the Paroo River, can be seen flowing into the Darling near the image center.
Today the Darling is in poor health, suffering from overuse of its waters, pollution from pesticide runoff and prolonged drought. In some years it barely flows at all. The river has a high salt content and declining water quality.
