Blue-green algae Red Alert lifted for Hunter River upstream of Glenbawn Dam

The Red Alert was lifted following two consecutive laboratory algal reports which indicates that the river site is no longer on red alert for blue-green algae.

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 is naturally occurring and can reproduce quickly in still or slow-flowing water when there is abundant sunlight and sufficient 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.
