Water Quality
The Corangamite Catchment Management Authority and the Environmental Protection Agency advise that individuals avoid contact with the river for at least 48 hours following heavy rainfall. This precaution is to ensure public safety, as water quality may be impacted by runoff from surrounding areas.

BLUE-GREEN ALGAE FOR BARWON RIVER GEELONG
During warmer weather, Corangamite CMA closely monitors the waterway for blue-green algae. When levels pose a health risk, some water-based activities may be restricted or the Barwon River temporarily closed.
Conditions can change quickly, so please check recreation and safety notices before you go. Corangamite CMA will keep the community informed of any changes. Public safety is our top priority. If you feel unwell after contact with water, seek medical advice.
What is blue-green algae?
Blue-green algae are naturally occurring bacteria in our waterways. Hot weather and still water provide ideal conditions for algae levels to increase in our rivers, streams and channels.
Blue-green algae contain toxins that are harmful to humans and animals.
It is not known how long the blue-green algae will remain at high levels.
How is blue-green algae detected?
Water sample are sent to a laboratory, where the blue‑green algae are identified and counted under a microscope.
When high levels are detected Corangamite CMA issues alerts warnings and advice through its website and the media.
Can blue-green algae be removed?
Blue-green algae are very small and Corangamite CMA cannot remove them.
Chemicals that kill blue-green algae cannot be used in natural waterbodies due to their impact on other creatures that live in the water.
How do I find out if there is a warning?
Current warnings can be found on the Corangamite CMA website, and social media channels.
Warning signs are placed at major recreational areas.
When levels decline the website and our media channels will be updated and warning signs will be removed.
