The Warrego River is an intermittent river that is part of the Darling catchment within the Murray–Darling basin, which is located in South West Queensland and in the Orana region of New South Wales, Australia. The Warrego River is the 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 over its 1,380-kilometre 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.
The Warrego River is one of a few rivers where silver perch breed naturally.[4] Golden perch and murray cod are also found in the river.
