Flow-MER is the Commonwealth Environmental Water Holder’s on-ground Monitoring, Evaluation and Research program.

We work in partnership with scientists, water managers and communities across the MurrayDarling Basin to help us understand how fish, birds, vegetation and river connectivity are responding to Commonwealth environmental water.

The Flow-MER program team acknowledge and respect the Traditional Owners as the First Peoples of the lands and waters of the Murray Darling Basin.

We recognise their unique ability to care for Country and their deep spiritual connection to it. We honour Elders past and present whose knowledge and wisdom has ensured the continuation of culture and traditional practices.

We are committed to genuinely partner, and meaningfully engage, with Traditional Owners and Aboriginal communities to support the protection of Country, the maintenance of spiritual and cultural practices and their broader aspirations in the 21st century and beyond. In particular we acknowledge the Traditional Owners of the seven Selected Areas where Flow-MER research is focussed.

WEBINAR RECORDINGS

Flow-MER Fridays – Autumn 2024

The Flow-MER Friday webinar series is an opportunity to hear firsthand the activities and outcomes taking place in the Flow-MER Program. The Autumn 2024 series looked at:

  • Environmental Water: supporting the right plants in the right places
  • Flows, fish and connectivity
  • Species conservation in the age of uncertainty.

Why Flow-MER?

Monitoring, evaluation and research (MER) are critical to ensure that the use of Commonwealth environmental water achieves the best outcomes for our rivers, wetlands and floodplains, as well as the animals, plants and people that depend upon them. The Flow-MER Program continues the work undertaken through the Long-Term Intervention Monitoring (LTIM) Project and Environmental Water Knowledge and Research (EWKR) Project, which have provided us with a strong base from which to continue our investigations.

Flow-MER is the primary means by which the Commonwealth Environmental Water Holder (CEWH) monitors and evaluates the delivery of Commonwealth environmental water in the MurrayDarling Basin.  Flow-MER supports environmental water managers, demonstrates outcomes, informs adaptive management, and fulfils the legislative requirements associated with managing Commonwealth environmental water.

Flow-MER is a Basin-wide project that has two components:

  1. evaluation and research at the Basin scale that is organised around six Basin Themes and five cross-cutting themes
  2. site and area-scale monitoring at seven Selected Areas across the Basin. Research and monitoring undertaken at the Basin-scale and in the Selected Areas informs the evaluation of Commonwealth environmental watering.

Hydrology

The Hydrology Theme evaluates the extent to which Commonwealth environmental water contributes to improved connectivity (lateral and longitudinal) of watercourses in the Basin. It also produces the foundational annual datasets of flows with and without Commonwealth environmental water use at more than 100 sites in the Basin, and the maximum extent of annual inundation, used by other themes in their evaluations.

Biodiversity

The Biodiversity Theme evaluates the extent to which Commonwealth environmental water benefits waterbirds and selected animals (e.g. frogs, turtles) at different sites in the Basin.

Ecosystem Diversity

The Ecosystem Diversity Theme evaluates the contribution of Commonwealth environmental water to protecting and restoring the vast array of rivers, lakes, wetlands and floodplain ecosystems.

Fish

The Fish Theme is working closely with Selected Areas to understand, and evaluate, the extent to which Commonwealth environmental water contributes to population and movement dynamics of different native fish species in the Basin.

Vegetation

The Vegetation Theme evaluates the extent to which Commonwealth environmental water contributes to plant species diversity and vegetation community diversity in the Basin. 

Food Webs and Water Quality

The Food Webs and Water Quality Theme evaluates the extent to which Commonwealth environmental water contributes to stream metabolism through the lens of ecosystem respiration, primary productivity, dissolved oxygen levels and salinity regimes. 

Our Cross-Cutting Themes

Cross-cutting Themes provide a cohesive approach across the Evaluation and Research components of Flow-MER and include data visualisation, reporting, modelling, and stakeholder engagement and communications.

Where is Flow-MER happening?

Until 30 June 2024, Flow-MER worked across seven Selected Areas which chosen to provide geographic coverage of the Basin and include a range of key ecosystems and biota. These areas provide the monitoring data for the Basin-scale evaluations and have conducted research and engagement with their local communities. Many of their stories are available through this website. From 1 July 2024, Flow-MER increased the number of Selected Areas from seven to ten.

Lachlan

Lachlan

Led by the University of Canberra

The Lachlan River is one of three rivers of the Wiradjuri people, forming part of Songlines and Dreaming tracks. It has provided food, shelter and resources to the Wiradjuri people for between 40,000 and 65,000 years. It supports a diverse range of landscapes and species that vary enormously through extremes of weather conditions. Our work here focusses on monitoring the outcomes of environmental water in the lower Lachlan River system, from Lake Brewster to the Cumbung swamp.

Murrumbidgee

Murrumbidgee

Led by Charles Sturt University

The Murrumbidgee is a lowland river system with large meandering channels, wetlands, lakes, swamps and creek lines. Our work here focuses on understanding how native fish, waterbirds, reptiles and amphibians, as well as wetland vegetation communities, benefit from these targeted environmental watering actions.

Lower Murray

Lower Murray River

Led by the South Australian Research and Development Institute

The Lower Murray River is a complex system with diverse habitats supporting important water-dependent plants and animals. Our work here includes monitoring and evaluating the ecological responses to Commonwealth environmental water delivery.

Gwydir

Gwydir

Led by the University of New England

The Gwydir is a special place with significant environmental, cultural and economic values. Our work focuses on monitoring and evaluating the outcomes water for the environment enables in some of the largest waterbird breeding colonies in Australia. We also work in the rivers and floodplains to assess water quality, fish breeding and food webs.

Warrego–Darling

Warrego-Darling

Led by the 2rog Consulting

The WarregoDarling is a unique and diverse system that supports a rich diversity of plants and animals in a constantly changing environment.  Our work here focuses on monitoring ecosystem interactions and evaluating our findings to provide accurate and reliable information to the Commonwealth Environmental Water Holder for the effective management of environmental water.

Lower Goulburn

Lower Goulburn

Led by the Melbourne University

The Goulburn River is one of the hardest working rivers in the MurrayDarling Basin, providing water to support agriculture and rural communities, as well meeting growing downstream Murray River demands. At the same time, it is home to diverse flora and fauna. Our work focusses on assessing how environmental and consumptive (irrigation) flows affect the ecosystem of the Lower Goulburn River, and to help waterway managers to protect and enhance this vital water source into the future.

Edward/Kolety–Wakool

Edward/Kolety–Wakool

Led by Charles Sturt University

The Edward/Kolety–Wakool River system is a large anabranch of the Murray River in the southern Murray–Darling Basin. The system is a complex network of interconnected streams in a productive agricultural landscape. Our work in this system focuses on understanding how native fish, vegetation, water quality and processes that support and sustain aquatic food webs are influenced by targeted environmental watering actions.
