Blue-green algae warning for Tullaroop Reservoir

Tuesday 18 May, 2021

Goulburn-Murray Water (GMW) is warning customers and the public to avoid direct contact with water at Tullaroop Reservoir after monitoring detected high levels of blue-green algae.

Warning signs will be positioned at major recreational areas around Tullaroop Reservoir and will remain in place while high levels of blue-green algae are present. Tullaroop Reservoir will not be closed to the public.

GMW Manager Water Quality Greg Smith said people should avoid contact with the water at Tullaroop Reservoir due to high levels of blue-green algae, which may contain toxins that are harmful 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.

“Blue-green algae occur naturally in waterbodies and cannot be removed,” Mr Smith said.

“It is not possible to predict how long the algae will remain at high levels, and GMW will continue to monitor the situation.”

GMW recommends:

  • People and pets avoid contact with the water.
  • People 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.
  • Do not use affected water for cooking, drinking, washing or showering. Boiling the affected water will not make it safe for these purposes.
  • Reading GMW’s fact sheet and other information on blue green algae at GMW’s blue-green algae webpage ( to be informed of the risks.
