Tracking Golden Perch in the Lower Murrumbidgee

Eighty-one golden perch have been tagged with acoustic trackers in the Lowbidgee wetlands. Charles Sturt University researchers are now following their movements to uncover when and where they spawn, and how environmental water can best support their recovery.

Mosaic: Life on the Western Lakes

In south-western New South Wales, on Mutthi Mutthi country, the Murrumbidgee River reaches the Western Lakes. This is a mosaic of temporary and permanent wetlands, where environmental water is delivered to support vegetation and create habitats for water-dependent animals.

A collection of threatened and migratory species of the Murrumbidgee Valley

A range of threatened species make their home in and around the Murrumbidgee. These include brolgas, Australasian bitterns, southern bell frogs, and many other species. Knowing where these animals live is important. This information guides decisions about where and when to use wa

Basin-scale evaluation of 2022–23 Commonwealth environmental water: Synthesis Report

High rainfall in 2022-23 led to extensive flooding in the Murray-Darling Basin, boosting wetland health and supporting diverse plant and animal species.

The water requirements of the endangered Australasian bittern

Scientists use audio recorders to track the elusive Australasian bittern, revealing how water management can boost breeding success in key wetlands.

Celebrating 10 years of the CEWH’s science program Flow-MER

For a decade, the Commonwealth Environmental Water Holder (CEWH) has invested in science to ensure environmental water is planned, delivered and evaluated on a strong evidence base. The CEWH’s science program Flow-MER (Flow Monitoring, Evaluation and Research) has been central to this effort—building long-term datasets, strengthening partnerships and improving how outcomes are measured across the Murray–Darling Basin.

Species conservation in the age of uncertainty

Globally, freshwater vertebrates are declining rapidly, four times faster than their terrestrial counterparts, due to threats like habitat loss and invasive species. This presentation will discuss the challenges faced by threatened species in managed floodplains and explore the potential of environmental water management in conservation efforts.

Biodiversity in the Basin

Freshwater ecosystems are biodiversity hotspots. In the Murray-Darling Basin rivers and wetlands support numerous rare and threatened species and are vital habitats for many migratory waterbird species. We introduce the frogs, reptiles, waterbirds, mammals and monotremes in the Murray Darling Basin and discuss how managed environmental water deliveries can support biodiversity.

What can reptiles and frogs tell us about environmental flow delivery

The benefits of flow delivery and environmental water are likely to aid many other wetland dependant vertebrates – including frog-eating snakes – so what can they tell us about water management? In this webinar, Skye, Damian and Erin share their learnings about wetland dependant vertebrates like snakes and frogs, and their relationship with the delivery of environmental flows.
