URGENT UPDATE: The latest assurance report from the Murray-Darling Basin Authority (MDBA) reveals a concerning water shortfall that could significantly impact the region ahead of the crucial December 31, 2026 deadline. This report, released today, underscores that many key projects under the Sustainable Diversion Limit Adjustment Mechanism (SDLAM) may not be completed on time, threatening the Basin’s water management strategy.
Authorities confirm that the expected water supply will fall drastically short of the 605 gigalitres per year target set in 2017. Current estimates suggest the supply could range between 250 gigalitres and 350 gigalitres, resulting in a staggering shortfall of up to 355 gigalitres. This alarming update highlights the urgent need for collaboration among the state governments of New South Wales, Victoria, and South Australia to ensure that projects are completed and operational before the deadline.
MDBA Chief Executive Andrew McConville stated, “While we have seen successful outcomes from smaller projects, such as those at the Chowilla floodplain and Hattah Lakes, we are now facing a reality where many significant projects will not be delivered.” This is a critical moment for water management in the Basin, as the findings could have profound implications for agricultural communities, local ecosystems, and regional economies.
The report emphasizes the importance of timely project execution, noting that the final SDLAM supply contribution will ultimately depend on the completion of these essential initiatives. As the MDBA prepares for a final reconciliation in 2026, the stakes have never been higher for stakeholders involved in water management within the Basin.
Looking ahead, the MDBA plans to release a draft determination of the proposed SDL adjustment later in 2026, providing the public with an opportunity to voice their opinions before final decisions are made. The final determination will be submitted to the Australian Government Minister for Water by December 31, 2026, paving the way for critical decisions regarding the future of water resources in the Murray-Darling Basin.
Stay tuned for further updates as this situation develops, and consider the implications for local industries and communities that rely on these vital water resources. The need for action and collaboration has never been more urgent.
