Blue-green algae Red Alert warning for two locations at Wyangala Dam has been cleared
6 FEBRUARY 2023The red alert warning for blue-green algae for Wyangala Dam at the Inland Waters Park and the dam walllocationswas lifted following two consecutive algal sample results of lower than red alert level. The sites are now on amber alert for blue-green algae.
While on an 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 this sampling site 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.
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.
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 musky or earthy odour.
People who believe they may have been affected by blue-green algae are advised to seek medical advice.
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.
