We work along 10 river systems within the Basin, conducting targeted monitoring and research to understand local ecosystem responses and inform water management practices. The data is also used to help inform Basin Evaluation.

This digital booklet captures that journey. It reflects the progress, partnerships, and knowledge built through Flow-MER – the Basin’s largest and longest-running environmental water science program.
In January 2025, researchers heard an endangered Australasian bittern in the Gwydir Wetlands, where the species had virtually disappeared. With only 1,300 left in Australia, they hope environmental flows will bring a breeding comeback.
The latest evaluation reports from the Flow MER Program and CEWH highlight a decade of progress in delivering water for the environment across the Murray Darling Basin. Findings show how science, adaptive management and collaboration continue to shape outcomes for fish, birds, ve
Researchers and Flow MER teams are using drones and deep learning to monitor how lignum responds to water for the environment. With 91% accuracy across four river systems, this collaboration is helping build a clearer picture of how floodplain vegetation recovers and thrives.
Researchers reveal how waterbirds cope with Australia’s highly variable climate and hydrology, and how they “chase the floods” across vast distances. By attaching tiny satellite-tracking backpacks to 200+ birds, the project gathered more than 50,000 bird‑days of tracking data.
Kolety Werkul River Rangers worked with scientists to monitor the first environmental watering of Werai Forest since 2009. Blending cultural knowledge with science, they tracked how flows support the forest’s plants, animals, and cultural heritage.
Researchers, Aboriginal Elders, and water managers journeyed through the Lower Balonne to share cultural knowledge and science on river flows. Their insights are guiding smarter water management for communities, wetlands, and wildlife across the river system.
