Each spring, the mighty Murray cod begins its breeding journey in Australia's river systems.
These native fish rely on rising water levels and warmer temperatures to signal the arrival of spawning time. They swim upstream to lay thousands of eggs in shallow water and hollow logs. Their young, called fingerlings, need clean water, plenty of food, and connected habitats to survive. Water delivered by the Commonwealth Environmental Water Holder (CEWH) supports these needs.
Spring is a vital season for many species, like the Murray cod, a nationally Vulnerable threatened species. Fish migrate and breed, waterbirds nest, frogs call, and floodplain plants come alive. Spring flows also flush nutrients and improve water quality. They reconnect wetlands that may have been dry for months.
Water for the environment isn't just about conservation - it's about restoring balance. Spring flows are carefully planned to mimic natural seasonal patterns, helping ecosystems thrive. We work with delivery partners to manage releases from dams and weirs. This complements rainfall and natural river flows. In dry years, these flows can be crucial to prevent long-term ecological decline.
We work with other water managers, First Nations people, scientists, and local communities. We plan and deliver water where it's needed most. This collaborative approach helps protect biodiversity, cultural values, and community wellbeing.
As climate variability increases, supporting seasonal flows becomes even more important. Water for the environment builds resilience in our landscapes. Especially in spring, when life flourishes in the Basin.
