Blue-green algae Red Alert issued for the Hunter River upstream Glenbawn Dam

30 June 2021

A Red Alert warning has been issued for the Hunter River upstream Glenbawn Dam. The Red Alert will apply from Belltrees downstream to the upper reaches of the lake. A Stock Alert is also in place while high concentrations are present. There is currently no alert for Glenbawn Dam.

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 and pets. Stock owners should seek alternate sources of water and restrict stock access to affected areas of the river.

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. Fish fillet meals from algal bloom affected areas should be limited to 1-2 servings per week.

Blue-green algae usually appear as green paint-like scums on the surface, near the edges, or as greenish clumps throughout the water. The water can appear to be dirty, green, or discoloured and a strong musty or earthy odour may be noticed.

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 blue-green algae dissipate.

People who believe they may have been affected by blue-green algae are advised to seek medical advice.
