High levels of blue-green algae have been detected in Lake Boga, leading Goulburn-Murray Water to issue a warning to the public to avoid direct contact with the water.

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

Lake Boga will not be closed to the public.

“Blue-green algae occur naturally in waterbodies and cannot be removed, says GMW Water Quality Coordinator Bianca Atley.

“They 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.”

GMW has issued a list of recommendation for locals:

- 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 (g-mwater.com.au/news/bga) to be informed of the risks.

GMW is continue to monitor the situation, saying it's not possible to provide a prediction about how long the high levels will last.
