The Warrego River, an intermittent river that is part of the Darling catchment within the Murray–Darling basin, is located in the south west of Queensland and in the Orana region of New South Wales, Australia. The Warrego River is northernmost tributary of the Darling River.
The river rises from below Mount Ka Ka Mundi in the Carnarvon Range, near Tambo in Queensland, and flows generally south, reaching its confluence with the Darling River, downstream from Bourke. The river is joined by thirty-seven tributaries, including the Nive and Langlo rivers; descending 528 metres (1,732 ft) over its 1,380-kilometre (860 mi) course. The river flows through a series of reservoirs, including the Dillalah Waterhole, Ten Mile Waterhole, Lower Lila Dam, Six Mile Dam, Turtle Waterhole, and Boera Dam.
The towns of Augathella, Charleville, Wyandra, and Cunnamulla are located on the banks of the river.
Most of the basin of the Warrego is too dry for cropping and has a very erratic rainfall of between 350 and 500 millimetres (14 and 20 in). It is covered with a natural vegetation of grassland of more fertile clay soils, and saltbush shrubland on less fertile red earths. The predominant land use is low-intensity grazing of sheep and cattle: the river's flow is much too erratic to permit irrigated cropping. The Warrego is essentially an ephemeral stream: it is not unknown for years to pass without any flow in the basin and substantial amounts of water reach the Darling River only in wet years almost always associated with La Niña events.
