High levels of blue-green algae produce toxins that can affect the health of humans, animals, birds and livestock as well as harm the environment.
Blooms are common in the warmer months in Victorian rivers and lakes and can be triggered by a combination of:
- nutrients in the water
- low water inflows and storage levels
- warmer weather conditions
When we become aware of an algae bloom in one of our waterways, we may issue a warning. It's important that you respect any changes to recreational activities at lakes, reservoirs, rivers and wetlands where warnings are issued.
For warnings for the Murray River, refer to algal information issued by the NSW Department of Primary Industries.
How to recognise a blue-green algae bloom
Blue–green algal blooms often cause a green/red/brown discolouration of the water. Sometimes scum forms on the water surface and an earthy or musty smell may be present.
Although algae blooms can sometimes be seen, water samples need to analysed to know for sure.
If you suspect a blue-green algae bloom, contact us immediately on 1800 188 586.
Blue-Green Algae Regional Coordination Plan
GWMWater is the Regional Coordinator for a major blue-green algae outbreak for a number lakes, reservoirs, rivers and wetlands within our region.

The blue-green algae warning for Taylors Lake has been lifted. Testing of water samples and visual inspection indicates that the water in Taylors Lake is safe for recreational activities, including swimming, boating and fishing.
The water in Taylors Lake will continue to be regularly monitored.
GWMWater is warning the public to avoid direct contact with water in Lake Toolondo after monitoring detected levels of blue green algae above levels considered safe for recreational use.
