We’re planning to release environmental water into the Yarra River around late April to early May to support fish breeding.
Water reserved for the environment is used to maintain waterway health by mimicking the pattern of natural flows. This release, also known as an ‘autumn high’, aims to trigger the migration of fish down to the sea to spawn.
What the release involves
Monitoring of the Yarra River is showing that it has not received sufficient flows to support the plants and animals that live in it.
The ‘autumn high’ release will use approximately 10 gigalitres (10 billion litres) of water from the river’s Environmental Entitlement over three weeks. Water will be released from the Upper Yarra and Maroondah Reservoirs, resulting in river levels rising between 40cm and 90cm along the main branch for the Yarra.
