Blue green algae Red Alert warning

Published on 08 April 2020

A high-level algal warning (Red Alert) has been issued for the Murray River at Corowa, immediately downstream from Yarrawonga Weir and at Cobram. The red alert previously issued for Picnic Point and Tocumwal 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.
