Spring environmental flow for the Yarra

Yarra River at Warrandyte State Park

An environmental water release by Melbourne Water will assist in bolstering the population of numerous fish species in the Yarra River this spring.

The release, which mimics the natural flow of the river before human intervention, is anticipated to promote the spawning of Macquarie Perch in the Yarra system.

It’s predicted numbers of the species will increase through the release of 12 billion litres of water from the Upper Yarra, Maroondah and O’Shannassy reservoirs, as well as from the Maroondah Aqueduct at Yering Gorge.

Additionally, the release is expected to benefit other species – such as the River Blackfish, the endangered Australian grayling and the platypus – as well as maintain natural habitats and support native vegetation.

Environmental flow releases are also used to improve habitat connectivity and flush sediment and debris out of the waterway.

The release is part of a larger program initiated by Melbourne Water in conjunction with the Victorian Environmental Water Holder, which aims to improve river and wetland health across greater Melbourne.
