Algal red alert lifted for Pindari dam

The Severn River below Pindari Dam remains on Amber Alert.

Stock and domestic water users on the Severn River below the dam should apply a level of caution.

They should keep a check on water supplies and discontinue using these waters if algae become present.

While on an Amber Alert, the water at Pindari Dam is generally considered to be suitable for water sports, but water users are advised to exercise caution.

It is 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. The water should be considered unsuitable for potable use and alternative supplies or prior treatment of raw water for domestic purposes should be considered.

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.

Water users should use personal discretion at all times before entering a water body and be aware that the algal situation can change quickly.

WaterNSW will continue routine water quality monitoring and advise of any change as new results are received.

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.

Blue-green algae usually appear as green paint-like scums 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 who believe they may have been affected by blue-green algae are advised to seek medical advice.

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.
