New research investigates how to include future environmental change in water runoff models

Native fish species received a $639,000 boost in 2024, with 16 grants awarded to communities, government agencies, and environmental experts to improve river conditions.

For a long time, river modellers have faced the challenges of tracking water movement across landscapes. This task becomes more complex when different river catchments use different models. Along with jurisdictions, we are in the process of improving these systems and tools.

When establishing the Basin Plan it was determined that a portion of surface water and groundwater entitlements should be recovered and retained in the system, to improve the health of rivers, wetlands and groundwater systems. This is known as the water recovery target, and is a long-term average.

The MDBA is partnering with states to create new river modelling roles, enhancing capability and building a deeper understanding of the Basin.

Water is used for a wide range of purposes across the Murray−Darling Basin. Water from rivers, lakes and underground is used by communities, farmers and industries.

We're using the best available science and knowledge to help deliver a productive and healthy future for the interconnected rivers of the Murray–Darling Basin.

There’s a limit to the amount of water that can be taken from the rivers for towns, industries and farmers in the Murray–Darling Basin.

Long-term diversion limit equivalent (LTDLE) factors (also known as the Cap factors) were established to accurately assess how much water has been recovered for the environment, and to guide future water recovery decisions.

In 2012 the Basin Plan listed estimates of the average annual volumes of floodplain harvesting as components of the baseline diversion limit (BDL) in some northern Basin sustainable diversion limit (SDL) resource units. The New South Wales ‘Healthy Floodplains Project’ includes work to enable calculation of re-estimates of BDLs associated with floodplain harvesting in these northern New South Wales SDL resource units. These volumes will contribute to re-estimates of the total BDLs for all forms of take.
