Seqwater warns to watch out for blooms of lake algae

VISITORS to Seqwater lakes have been warned about potential outbreaks of blue-green algae this summer as temperatures start to rise.

The detection of the algae can lead to recreation restrictions at lakes.

Seqwater CEO Peter Dennis said a low level of blue-green algae was not detrimental to the environment.

"Under certain conditions though, the algae can grow rapidly and become a dominating nuisance," he said.

"Blue-green algae blooms generally occur in the warmer months due to increased water temperature and optimal light conditions. So it is likely we will see an increase in the algae in coming weeks.

"Various toxins released by some species of blue-green algae can present a potential health risk to visitors. Exposure to the algae can result in a rash developing. High levels of algae can cause headaches, nausea, muscular pains, diarrhoea and gastroenteritis."

Mr Dennis said Seqwater closely monitored all lakes for the presence of blue-green algae, in addition to other water quality issues.

"If we do need to close a lake to certain recreation activities, we install signage and put safety notices on our website," he said.
