Blue-green algae red alerts update for the Murray River and Neimur River

Blue-green algae red alerts update for the Murray River and Neimur River

21 April 2021

Red alert warnings have been issued for the Murray River at Moama/Echuca, Tooleybuc Euston Weir and downstream at Mount Dispersion. Further, a Red Alert is also in place for the Neimur River at Barham-Moulamein Rd. WaterNSW will continue to monitor sites 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 come into direct contact with the water. Contact with the water may also pose a threat to livestock and pets.

People should not eat mussels or crayfish from Red Alert warning areas. A precautionary approach should be applied to fishing during bloom events. Any fish caught should be cleaned and washed thoroughly in uncontaminated water and any internal organs disposed of before consumption. Fish fillet meals from algal bloom affected areas should be limited to 1-2 servings per week. Avoiding fishing in a bloom location is the best way to minimise risk, particularly catching and eating fish from locations with severe blooms that last extended periods of time. 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.

Blue-green algae usually appear as green paint-like scums on the surface, near the edges, or as greenish clumps throughout the water. The water can appear to be dirty, green or discoloured and a strong musty or earthy odour may be noticed.

Potentially harmful algal blooms tend to occur when there are warm water temperatures and sunny days, low turbidity, and calm water conditions where water may stratify. 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.
