Hydrologic Modelling of Connectivity Expert Panel Recommendations 2025–Scenario 3–Extended Resumption of Flow

Flow rates for imposing restrictions have been set at below baseflow for 90 consecutive days at trigger sites, flow rates for lifting restrictions have been set at the lower small fresh threshold for restriction trigger sites; flow rates must exceed the small fresh threshold for 14 days at restriction trigger sites for lifting restrictions. Supplementary and floodplain harvesting has been restricted in the regulated NSW Border Rivers, Namoi, Gwydir and Macquarie River systems when the closest downstream section in the Barwon –Darling is restricted. The 30 GL cumulative flow trigger at Bourke for lifting restrictions has been removed.

Three additional trigger locations included as recommended by Panel: Mungindi, Collarenebri and Louth.
