The Red Alert warning issued on 6 November 2024 for high levels of potentially toxic blue-green algae in the Copeton Dam has been lifted. Copeton Dam is now on Amber Alert.
While on Amber Alert, the water is generally considered to be suitable for water sports, but water users are advised to exercise caution.
Water users should use personal discretion at all times before entering a water body and be aware that the algal situation can change quickly.
The water should be considered unsuitable for potable use and alternative supplies or prior treatment of raw water for domestic purposes should be considered.
It is also advised not to drink untreated or boiled water from the dam due to the risk of stomach upsets. Boiling the water does not inactivate algal toxins.
As algal numbers can change dramatically with changes in conditions, water users should avoid water which is discoloured or gives off an earthy or musty odour.
WaterNSW will continue routine water quality monitoring and advise of any change as new results are received.
Blue-green algae is naturally occurring and can reproduce quickly in still or slow-flowing water when there is abundant sunlight and suIficient nutrients.
Visit the local council or local water utility websites for information about the management of blue-green algae risks in the nearby treated drinking water supplies.
