Blue-green algae warning for the Central Goulburn and Loddon Valley Irrigation Areas

Friday 24 March, 2017

Goulburn-Murray Water (GMW) is warning the public to avoid direct contact with water in various locations within the Central Goulburn and Loddon Valley Irrigation Areas after monitoring detected high levels of blue-green algae.

The following locations are affected by the warning:

  • Central Goulburn No.7, 8 and 9 channel systems – these are in the region west of Harston, Merrigum, Lancaster and Kotupna to approximately Echuca Village, Timmering, Carag Carag.
  • Loddon Valley irrigation customers east of the Loddon River (including Dingee, Mitiamo and Pyramid Hill), but not the East Loddon pipeline.

GMW recommends water users from affected areas seek an alternative water supply where possible.

GMW recommends:

  • Wherever possible alternate water supplies should be used.
  • Untreated water should never be used for human consumption. For example drinking, cooking, showering, bathing and washing.
  • Boiling the affected water will not make it safe to use. Blue-green algae release toxins into the water when heated.
  • People should avoid contact with the water.
  • Stock and pets should be kept away from blue-green algae affected water.
  • Water can be used on gardens, however water should not be sprayed on vegetables and fruit.
  • Stock should be kept away from recently irrigated areas for at least seven days.
  • Reading GMW’s fact sheet and other information on blue green algae at GMW’s blue-green algae webpage ( www.g-mwater.com.au/bluegreenalgae-alert) to be informed of the risks. 

Blue-green algae occur naturally in waterbodies. They 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.

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

GMW is continuing to monitor the situation.

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