Blue-green algae alert for the Werribee River

Wednesday 13 January 2016
​Melbourne Water is advising people to avoid contact with the Werribee River, downstream of the Maltby Bypass, following the detection of blue-green algae.

Melbourne Water Waterways Manager (West Region), Cameron Howie, said there were many forms of blue-green algae and the species currently present in the river could be harmful to animals or humans.

“It’s important that people and their pets avoid contact with the water and make sure that it does not come into contact with their skin or eyes,” said Mr Howie.

“Anyone who diverts water from the Werribee River near the Maltby Bypass should stop doing so while the bloom is active.”

Mr Howie said signs had been erected in the area to warn people of the potential hazards, and regular sampling of the water would continue to monitor the problem.

Melbourne Water is working with other authorities to manage the algae bloom in line with Victorian Government guidelines.

Blue-green algae occurs naturally in waterways and forms blooms during hot weather, periods of drought or low flow, or where there is an accumulation of nutrients in waterways or water bodies.
