Reason: Blue-Green Algae
Regular testing has detected levels of blue-green algae above levels considered safe for recreation use at Lake Wallace in Edenhope.
We warn the public to avoid direct contact with the water. People may still boat, sightsee and enjoy other activities at the lake that do not involve direct water contact.
Warning signs have been positioned at major recreational areas around the lake and will remain in place while the warning is current.
Blue-green algae warnings
We advise the public to avoid direct contact with water bodies that have been issued a blue-green algae warning. Monitoring has detected levels of blue-green algae above levels considered safe for recreational use.
- Avoiding all contact with affected water.
- Affected water not be used for cooking, drinking, washing/showering or any other domestic use. Boiling the affected water will not make it safe to use.
- People who come into contact with the affected water should wash skin immediately in clean water. Characteristic signs of algae contact are skin rashes or itchiness, sore eyes, ears and nose; or if swallowed, nausea or vomiting.
- Those experiencing any health issues after being in contact with blue-green algae affected water, please seek medical advice immediately.
- Pet owners should prevent pets from drinking or having direct contact with blue-green algae affected water.
Anglers wanting more information please visit Victorian Fisheries Authority website.
Warning signs have been positioned at major recreational areas around the site and will remain in place while there are elevated levels of blue-green algae.
High levels of blue-green algae produce toxins that can affect the health of humans, animals, birds and livestock as well as harm the environment.
Blooms are common in the warmer months in Victorian rivers and lakes and can be triggered by a combination of:
- nutrients in the water
- low water inflows and storage levels
- warmer weather conditions
When we become aware of an algae bloom in one of our waterways, we may issue a warning. It's important that you respect any changes to recreational activities at lakes, reservoirs, rivers and wetlands where warnings are issued.
For warnings for the Murray River, refer to algal information issued by the NSW Department of Primary Industries.
How to recognise a blue-green algae bloom
Blue–green algal blooms often cause a green/red/brown discolouration of the water. Sometimes scum forms on the water surface and an earthy or musty smell may be present.
Although algae blooms can sometimes be seen, water samples need to analysed to know for sure.
If you suspect a blue-green algae bloom, contact us immediately on 1800 188 586.
Blue-Green Algae Regional Coordination Plan
GWMWater is the Regional Coordinator for a major blue-green algae outbreak for a number lakes, reservoirs, rivers and wetlands within our region.
