WaterNSW red alert for blue-green algae at Goodhope in Burrinjuck Dam

17 April 2018

WaterNSW has issued a red alert warning for blue-green algae at Goodhope in Burrinjuck Dam.

Algal warning signs will be erected and additional water samples will be taken and analysed to determine the full extent of the algal outbreak.

A red alert level warning indicates that people should not undertake recreational activities where they may come into direct contact with the water, such as swimming, as well as domestic uses including showering and washing.

Contact with the water may also pose a threat to livestock and pets. Warning signs will remain in place while high levels of blue-green algae are present.

Blue-green algae are potentially toxic and may cause gastroenteritis in humans if consumed and skin and eye irritation after contact. Boiling the water does not remove algal toxins. People are advised not to enter the water, not to drink untreated water or bathe in water drawn from the dam while this red alert level warning is in place.

Livestock owners are reminded to continue to check stock water supplies for blue-green algae and to remove stock from foreshores where surface scum is visible or blue-green algae are suspected.

Blue-green algae usually appear as green paint-like scum on the water, near the edges, or as greenish clumps throughout the water. It makes the water appear dirty, green or discoloured and generally has a strong musty or earthy odour.

People should not eat mussels or crayfish from red level warning areas. Any fish caught should be cleaned and washed thoroughly in uncontaminated water and any internal organs disposed of before consumption.

Blue-green algae occur naturally and can reproduce quickly in favourable conditions where there is still or slow-flowing water, abundant sunlight and sufficient levels of nutrients.

It is not possible to predict how long the algae will remain at high levels. Regular monitoring will continue and the alert will be lifted as soon as the high levels of algae dissipate. People who believe they may have been affected by blue-green algae are advised to seek medical advice.

Information updates about blue-green algae blooms and red level warning areas can be obtained from the Regional Algal Coordinating Committee free-call Algal Information Hotline on 1800 999 457 or visit our algae webpage.
