COVID-19 update: As an essential service provider, we are continuing construction and field work where it is safe to do so. We’re following up-to-date State health advice, including specific hygiene and social distancing protocols. Read more.

We’re planning to release environmental water into the Werribee River in September or October, to improve habitat for animals including frogs and bugs.

This water, reserved for the environment, maintains waterway health by mimicking the pattern of natural flows.

What the release involves

Monitoring of the Werribee River is showing that it has not received sufficient flows to support the plants and animals that live in it.

This ‘spring fresh’ involves releasing water from Lake Merrimu into Pyrites Creek at Bacchus Marsh. During the release period, we’re aiming to achieve flows of:

  • 130 megalitres (130 million litres) a day for 2 days
  • 2 megalitres a day for 30 days
  • 440 megalitres of the river’s Environmental Entitlement used in total

This release aims to improve habitat for frogs and bugs – a natural food source for a variety of animals.
