Blue-green algae warnings for Newlyn and Tullaroop reservoirs

Thursday 18 November, 2021

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

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

GMW Water Quality coordinator Bianca Atley said Newlyn and Tullaroop reservoirs would not be closed to the public and visitors could still sightsee and enjoy other activities that did not involve direct contact with the water.

Blue-green algae occur naturally in waterbodies and contain toxins 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.

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.

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

This is the first warning issued for Newlyn Reservoir since detailed records were kept from 2003 and the 14th alert for Tullaroop Reservoir.

Water supplied by GMW is not suitable for human consumption without first being properly treated.

Human consumption includes showering, bathing, washing, cooking, ice making and drinking.
