Algal bloom at West Barwon Reservoir

13 Sep 2018

Drinking water is not affected, and remains 100% safe to drink.

We’re monitoring a blue-green algae (cyanobacteria) bloom at West Barwon Reservoir.

The bloom was likely caused by the burst of warm and sunny weather, resulting in the reservoir appearing green and having an odour. This is completely normal for this type of event.

We optimise and adjust our treatment plant processes to ensure to continued supply of safe, high-quality drinking water.

We’ve posted some signage at the reservoir to alert visitors. While you can still enjoy birdwatching, walking, mountain biking and picnicking, we advise against fishing until the bloom clears and the signs are removed.

We will continue to monitor the reservoir and the Barwon River downstream, and have increased our regular water testing schedule.
