Blue green algae Red Alert warning lifted at Burrendong Dam

30 April 2020

The previously issued high level algal warning (Red Alert) at Burrendong Dam, located 30 kilometres south-east of Wellington in the Central West region.

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

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.
