GWMWater has warned the public to avoid direct contact with water in the lake after regular monthly testing detected levels of blue-green algae above levels considered safe for recreational use.

Warning signs have been positioned at major recreational areas around the lake and will remain in place while the warning is current.

People can still boat, sightsee and enjoy other activities at the lake that do not involve direct water contact.

GWMWater recommends people avoid all contact with affected water. If you come into contact with affected water, you should wash affected skin immediately in clean water.

Blue-green algae occurs naturally and can be dangerous to humans and animals.

Characteristic signs of algae contact are skin rashes or itchiness, sore eyes, ears and nose; or if swallowed, nausea or vomiting

GWMWater said it was not possible to predict how long the algae will remain at high levels within the lake. The lake will be regularly monitored.
