When a specific river or wetland location, or ‘site’ in the Murray–Darling Basin is identified as requiring water to support or restore its health, the site is allocated an amount of water. With the strategic objectives defined, it’s time to deliver the water.

Delivery agencies

The Murray-Darling Basin Authority works to support federal, state and local agencies to deliver the right amount of water, when and where it’s needed most.

Structures to deliver water

Water is delivered in a variety of ways depending on the site, and the desired outcomes. For example, water can be released from a dam into a river, or transferred to a wetland via pumps, gates and other purpose-built structures, known as environmental works.

Works – built at key points along the Murray–Darling system – include dams, weirs, locks, levee banks, pumps and regulators. They assist water managers to transport, store, hold back or deliver the right amount of water when, where and how it’s needed most. These structures allow effective environmental water delivery to maximise its ecological benefits.

Monitoring and reporting

Once water for the environment has been planned, monitoring commences. The specific environmental objectives for the delivery of water (for the improved health of native vegetation, fish or waterbirds, or to improve river flows and connectivity) are monitored, and results are reported.

We continue to gain a better understanding of the outcomes these watering events have. As we learn more about how the Murray–Darling Basin system responds to water for the environment, we will continue to revise, rework and improve its delivery and effectiveness.
