Blue-green algae downstream from Fort Courage to Lock 9

17 March 2020

A red alert level warning (high alert) for potentially toxic blue-green algae has been issued for the River Murray immediately downstream from Fort Courage to Lock 9.

Also, there is now a high caution advisory in place for Lake Cullulleraine. The red alert issued for the section of river from Psyche Bend to Fort Courage remains current.

WaterNSW and Lower Murray Water will continue to monitor water quality along the river impacted by the algal bloom and report the results as soon as they become available.

A red alert level warning indicates that people should not undertake recreational activities where they may be coming into direct contact with the water.

Contact with the water may also pose a threat to livestock, and pets. The dominant cyanobacteria detected are known to be toxin producers and may produce a strong musty odour.

People are advised not to enter the water, not to drink untreated water or bathe in untreated water while a red alert level warning is in place. Boiling the water will not remove algal toxins.

People should not eat fish, mussels or crayfish from red alert warning areas.

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

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.

It is not possible to predict how long the algae will remain at high levels. Regular monitoring will continue, and the alert will be lifted as soon as the high levels of algae dissipate.

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