Darling river

The Darling River is the third-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. The Darling River is the outback’s most famous waterway.

The Darling is in poor health, suffering from over-allocation of its waters to irrigation, pollution from pesticide runoff, and prolonged drought. During drought periods in 2019, it barely flowed at all. The river has a high salt content and declining water quality. Increased rainfall in its catchment in 2010 improved its flow, but the health of the river will depend on long-term management.
