DRYING FROM THE BOTTOM UP – COMPOUNDING IMPACTS OF CLIMATE CHANGE AND OVER EXTRACTION IN THE DARLING RIVER SYSTEM, ONE OF AUSTRALIA’S LARGEST RIVERS
The Barwon-Darling is one of Australia’s most hydrologically variable dryland river systems, with periods of low flow and small flow pulses, or freshes, punctuated by large overbank flows that fuel large scale riverine productivity. The Barwon-Darling River and its associated tributaries is also a highly developed river system with more than 50% of the in-channel flows extracted for agriculture. During 2018-2019 the northern Murray-Darling Basin was in severe drought with very little inflows into the tributaries – this made national and international headlines with the large fish kills at Menindee in December 2019 and January 2019. By late 2019 the river had mostly dried in its lower reaches between Bourke and Menindee with catastrophic consequences for both fauna and flora and there was no water for irrigation. Since the DRAFT Interim Unregulated Flow Management Plan for the Barwon-Darling River was published in 1992 there have been a number of attempts to have the low flows in the Barwon-Darling protected from extraction. Have we left it too late? Is the Barwon-Darling to be Australia’s Aral Sea or Colorado River?
