Reduced to a string of stagnant mustard-coloured pools, fouled in places with pesticide runoff and stinking with the rotting carcasses of cattle and fish, the Darling River is running dry. The parched earth of Australia's longest waterway, if tributaries are included, is in the grip of the continent's most severe drought in a century. At Menindee, 830 km west of Sydney, despair has turned to anger as residents blame the government for exacerbating the drought by drawing down river water in 2017 for irrigation and other uses downstream. Locals now avoid using tap water for drinking and washing babies and children, saying it has caused skin irritation, and prefer boxed and bottled water instead.
