8 WaterNSW Northern Basin First Flush Event

• The 2020 Northern Basin First Flush Event: • Followed an extensive period of hot and dry conditions with record low rainfall and record low inflows • Included significant inflows from across the Northern Basin including the Border, Moonie, Gwydir, Namoi, Culgoa, Bokhara, Macquarie, Bogan and Warrego systems. • Involved a large number of Temporary Water Restrictions being placed on extractions in the Northern Basin. • Raised issues regarding communication and decision making processes. • Resulted in the appointment of an Independent Panel to assess the management of the event – https://www.industry.nsw.gov.au/water/allocations-availability/northern-basin-first-flush-assessment – Terms of Reference, consultation, Water User Reference Group – Final report with recommendations – end of August 2020 • Resulted in around 585 GL of inflow arriving into the Menindee system.

WaterNSW published regular Operations Updates throughout the event at https://www.waternsw.com.au/supply/regional-nsw/operations-updates
