Blue-green algae red alert lifted for Macintyre River

A red alert warning for blue-green algae in the Macintyre River has now been lifted.

The high alert for the toxic algae was issued for the Macintyre River at Boggabilla, Toomelah and Goondiwindi in June, however monitoring by WaterNSW and Goondiwindi Regional Council has shown a reduction in concentrations of blue-green algae, prompting the removal of the red alert.

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 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.

WaterNSW has urged anyone who believes they may have been affected by blue-green algae to seek medical advice.
