Monitoring conducted by WaterNSW has shown that concentrations of blue-green algae have declined prompting the lifting of the Red Alert.

An Amber alert is now in place and the relevant cautions apply.

Livestock owners are reminded to continue to check stock water supplies for blue-green algae and to remove stock from foreshores if surface scums becomes visible or blue-green algae are suspected.

Blue-green algae occur naturally and can reproduce quickly in favourable conditions where there is still or slow-flowing water, abundant sunlight and sufficient levels of nutrients. 

Blue-green algae usually appear as green paint-like scums on the water, near the edges, or as greenish clumps throughout the water.

It makes the water appear dirty, green or discoloured and generally has a strong musty or earthy odour.

People who believe they may have been affected by blue-green algae are advised to seek medical advice.
