Flows in the River Murray system vary widely depending on a range of factors, including rainfall, inflows, evaporation, and demands for water from all users.

The Murray–Darling Basin Authority (MDBA) met for the first time this year on 12 and 13 February 2025 on the lands of the Ngunnawal people in Canberra (ACT).

​​This study explored the ability to develop reference curves to describe exemplar age class distributions for key floodplain tree species. ​ ​​Understanding the characteristics of tree populations, such as their density, age structure, rates of recruitment (germination and establishment of new trees), growth, and mortality (death rates), are important to understanding the likelihood that tree populations are sustainable. This includes understanding the role of these processes on age class distributions. Developing reference curves – tools that help to define the acceptable limits of parameters such as age class distributions – helps us to determine the likelihood that tree populations are sustainable or may require management intervention to promote recruitment or old growth for example. ​

This report presents a stocktake and analysis of completed, current and proposed activities and initiatives which focus on improving longitudinal surface water connectivity across the northern Murray–Darling Basin (the northern Basin) ‘to and through’ Menindee Lakes. Longitudinal connectivity along and between river reaches is critical for maintaining healthy ecosystems and supports a wide range of social, cultural and economic values.

Sam joined the Murray–Darling Basin Authority (MDBA) in December 2024, and will be working alongside 7 other REO’s as we embark on a big year in our journey to Rivers, for generations.

Transfers from Dartmouth Dam to Hume Dam are expected to continue throughout February and the coming months if conditions remain dry.

The Basin Plan sets sustainable diversion limits (SDL). This is how much water can be used in the Murray–Darling Basin by towns and communities, farmers and industries, while keeping the rivers and the environment healthy. To provide flexibility, the Basin Plan includes a mechanism to adjust sustainable diversion limits.

The Basin Plan requires that the Authority undertake a reconciliation of the 2017 adjustment to sustainable diversion limits, if it considers that the result as at 31 December 2026 would be different to the 2017 determination.

To provide flexibility, the Basin Plan includes a mechanism to adjust sustainable diversion limits (SDLs). The mechanism requires a suite of measures to be implemented – the package of supply measures are designed to allow Basin Plan environmental outcomes to be achieved with less water. The package of efficiency measures will achieve enhanced environmental outcomes.

Under the sustainable diversion limit adjustment mechanism (SDLAM), a range of measures were brought forward by Basin state governments that were expected to deliver equivalent environmental outcomes and keep 605 gigalitres (GL) of water in consumptive use.
