Blue green algae Red Alert warning lifted for Cobram and Tocumwal

Blue green algae Red Alert warning lifted for Cobram and Tocumwal

16 April 2020

The previously issued high level algal warning (Red Alert) for Cobram and Tocumwal on the Murray River has been cleared. Monitoring conducted by WaterNSW has shown that concentrations of blue-green algae have declined considerably.  Red alerts issued for Corowa and immediately downstream from Yarrawonga Weir remain current until consecutive weekly results fall below the high alert threshold.

The reduction in the blue-green algal growth within mid reach of the Murray River can in part be attributed to lower water temperatures and increased flows.

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.
