Alexandrina Council has reissued a warning for dog owners to beware blue green algae in Lake Alexandrina and Goolwa Channel.

The SA Health alert for the region remains in place, with recent water samples showing algae levels are declining but toxin levels remain elevated, particularly in the Goolwa Channel area.

While the cold weather may deter humans from swimming, dogs are not so fussy and the council warns that pets are particularly vulnerable and should be kept out of the water.

SA Health says water from Lake Alexandrina should not be ingested and neither people not dogs should swim or dive until further notice.

“Unlike other blue green algae, the species detected at Lake Alexandrina generally does not form scum and is not easily visible to the naked eye. 

“This species has not previously been detected in such high numbers in South Australia.

“SA Water does not take water from the lake and has confirmed that all drinking water supplies in the area are safe.

“Pets are particularly vulnerable and should be kept out of the water. Algae may also stick to their fur, giving them a higher exposure.”

SA Health has given the OK for boating and fishing, but the advice is that fish caught in the lake should be cleaned and gutted thoroughly before being eaten. 

Lake Albert does not currently pose a health risk.
