Murray-Darling Basin Authority

Our vision is to achieve a healthy working Basin by managing its water resources for the long-term benefit of all Australians, working with partner governments and the community. We work to protect the Murray–Darling Basin and meet the social, economic and environmental needs of the Basin and its communities. We oversee the roll out of the Basin Plan and operate the River Murray on behalf of NSW,

Victoria and SA Governments. State governments are responsible for an individual’s water entitlements and allocations.

We’ve released our What We Heard report for the Menindee Lakes Review.

People across the Basin have shared what matters to them about the future of the Menindee Lakes.

We heard the views, knowledge, concerns and ideas shared by First Nations peoples, local and River Murray communities, peak and regional organisations and the broader public.

Your insights will help guide the next stage of the Menindee Review as we work with River Murray governments to investigate options and pathways for the future management of the Lakes.

Thank you to everyone who took the time share their views and experiences 🤝
