Barwon River, a perennial river that is part of the Murray–Darling basin, is located in the north-west slopes and Orana regions of New South Wales, Australia.
The name “barwon” is derived from the Australian Aboriginal words of barwum or bawon, meaning great, wide, awful river of muddy water; and also baawan, a Ngiyambaa name for both the Barwon and Darling rivers.[1] The history, culture and livelihoods of the local Aboriginal people are closely intertwined with the Barwon River and its associated tributaries and downstream flows.[4]
The river is formed through the confluence of the Macintyre River and Weir River (part of the Border Rivers system), north of Mungindi, in the Southern Downs region of Queensland. The Barwon River generally flows south and west, joined by 36 tributaries, including major inflows from the Boomi, Moonie, Gwydir, Mehi, Namoi, Macquarie, Bokhara and Bogan rivers. During major flooding, overflow from the Narran Lakes and the Narran River also flows into the Barwon. The confluence of the Barwon and Culgoa rivers, between Brewarrina and Bourke, marks the start of the Darling River.
Towns on the Barwon River, from its source towards its mouth include Mungindi, Collarenebri, Walgett, and Brewarrina.
The catchment and water flows of the Barwon River are generally administered by the Murray–Darling Basin Authority and together with the Darling River, the catchment covers about 13% of the Murray-Darling Basin.[4]
In December 2018 midst drought, the Barwon River at Walgett ceased flowing, reduced to a series of stagnant pools.[5]
