Blue-green algae warning for Lake Eppalock

Monday 30 March, 2026

Goulburn-Murray Water (GMW) is warning people to avoid direct contact with water in Lake Eppalock after monitoring detected high levels of blue-green algae.

Warning signs will be positioned at formal recreational areas around the lake and remain in place while high levels of blue-green algae are present.

Lake Eppalock will remain open to the public for any activities that do not involve direct contact with the water while the warning is in place.

GMW Water Quality Coordinator Bianca Atley asked people to take care around the water.

“Blue-green algae occur naturally in waterbodies but contain toxins harmful to humans and animals,” she said.

“Contact with it can cause rashes; sore eyes, ears, and nose; or, if swallowed, nausea or vomiting. It is therefore important for people boating or enjoying activities near the water to take extra precautions.” GMW recommends:

• People and pets avoid contact with the water.

• Those who come into contact with affected water should wash affected skin immediately in clean cold water.

• Seeking an alternative water supply for stock and pets where possible.

• Not using affected water for cooking, drinking, washing or showering. Boiling the affected water will not make it safe for these purposes.

It is not possible to predict how long the algae will remain at high levels.

Ms Atley said this latest blue-green algae warning at Lake Eppalock was the 14th warning issued at the site since records began in 2004.

“It’s important to keep in mind that blue-green algae are natural, unpredictable and their levels can change very quickly,” she said.

“There is no one factor that GMW can pinpoint as the cause of high levels of blue-green algae at one of its storages or waterways including Lake Eppalock. “

"Staff will continue to monitor blue-green algae levels at Lake Eppalock and will remove the warning when it is safe to do so.”
