Broken River blue-green algae warning extended to Shepparton

Tuesday 13 February, 2024

Goulburn-Murray Water (GMW) is warning the public to avoid contact with water in the Broken River downstream of Lake Nillahcootie to Shepparton due to potentially high levels of blue-green algae.

The warning issued earlier this month for Lake Nillahcootie to Caseys Weir has been extended to include the Broken River to Shepparton, as well as the Broken Creek from Caseys Weir to Katamatite.

Lake Benalla is situated on the Broken River and is included in this warning. The Broken River warning does not affect water used for Benalla’s drinking water supply.

Lake Nillahcootie also has a current warning for high levels of blue-green algae.

At this stage there is no expected impact on the Goulburn River, which joins the Broken River at Shepparton, although the Goulburn River will be monitored as a precaution.

The blue-green algae warning currently has no impact on the Shepparton drinking water supply.

GMW is the designated Regional Coordinator for managing blue-green algae warnings in the Broken River. The warning is being managed in conjunction with other agencies such as the Department of Health, the Department of Energy, Environment and Climate Action, Agriculture Victoria, urban water corporations, the Goulburn Broken Catchment Management Authority, local government and Parks Victoria.

Regional Coordinator Bianca Atley said GMW customers and the public downstream of Lake Nillahcootie should be on the lookout for scums in the area and monitor their water supply in coming days.

“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. If you are near the water, take extra precautions.”

It is recommended:

  • 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.

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.
