Blue green algae Amber alert is current at Buronga
Green alerts are also current at Echuca/Moama, Tooleybuc, Euston, MtDispersion, Curlwaa, Fort Courage, Lock 8 and Lake Victoria outlet.
The potentially toxic species identified from monthly sampling along the Murray River was the colony forming cyanobacteria Microcystis sp. As one of the most common bloom-forming cyanobacterium Microcystis exhibits phenotypic plasticity, readily adapting to a wide range of environmental conditions including water temperatures from 12 to 30 º.
Weekly 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.
