Blue-green algae Red Alert lifted for Darling River BHWB Pumping Station at Menindee

14 JUNE 2024

The Red Alert warning issued on 18 March for high levels of potentially toxic blue-green algae for Darling River BHWB Pumping Station at Menindee has been lifted. The storage is now on Amber Alert.

The Red Alert was lifted following two consecutive laboratory algal reports which indicates that this location is no longer on red alert for blue-green algae.

This latest advisory is one of a number in place for the Menindee lakes and Lower Darling. The situation is changing regularly as test results are received. WaterNSW is advising the community to continue to check the algae section of the WaterNSW website (waternsw.com.au/algae) for the most current information.

While on Amber Alert, the water is generally considered to be suitable for water sports, but water users are advised to exercise caution.

It is also advised not to drink untreated or boiled water from the dam due to the risk of stomach upsets. Boiling the water does not inactivate algal toxins.

The water should be considered unsuitable for potable use and alternative supplies or prior treatment of raw water for domestic purposes should be considered.

As algal numbers can change dramatically with changes in conditions, water users should avoid water which is discoloured or gives off an earthy or musty odour.

Water users should use personal discretion at all times before entering a water body and be aware that the algal situation can change quickly.

WaterNSW will continue routine water quality monitoring and advise of any change as new results are received.

Blue-green algae is naturally occurring and can reproduce quickly in still or slow-flowing water when there is abundant sunlight and sufficient nutrients.

Visit the local council or local water utility websites for information about the management of blue-green algae risks in the nearby treated drinking water supplies.

Updates and information about blue-green algae blooms and red level warning areas can be obtained by visiting waternsw.com.au/algae or calling 1800 999 457.
