A high-level algal warning (Red Alert) has been issued for the Murray River at Buronga and Mildura. The red alert previously issued for downstream Merbein pump station to Lock 9 remains current. This declaration of a red alert follows testing undertaken by WaterNSW. Levels of blue green algae in other sections of the river continue to fluctuate.

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.
