Blue-green algae Red Alert for Macquarie River at Wellington, Geurie extending to Dubbo

08 April 2019

A red alert level warning (high alert) for blue-green algae has been issued the Macquarie River extending from Wellington to the Dubbo area.

A red alert level warning indicates that people should not undertake recreational activities where they may be coming into direct contact with the water. Contact with the water may also pose a threat to livestock, pets and domestic users that pump directly from the river. Town water supplies remain unaffected and safe to drink.

Water users should lookout for signs of algae as river flows may push the algae downstream. Information on the visual identification of algae scums is on the WaterNSW website. http://www.waternsw.com.au/water-quality/algae.

People are advised not to enter the water, not to drink untreated water or bathe in untreated water drawn from the river while a red alert level warning is in place.

People should not eat mussels or crayfish from red alert 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 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

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.
