Maitland City Council raised a high alert for Telarah Lagoon and Walka Water Works Wednesday after recent water sampling indicated levels of blue green algae.
Residents have been urged to wash vehicles on grassed areas, remove leaves and clippings from gutters and to apply fertilisers only by packet instructions to avoid nutrients flowing into the local government area's waterways and increasing the likelihood of algae bloom.
'Once an algal bloom has developed, there isn't much authorities can do to reverse the situation except wait for a change in weather conditions. Council will continue to monitor the lagoons at Walka Water Works, Telarah and Rathluba for Blue Green Algae growth," the council's environment and sustainability manager, Catherine Pepper, said.
Domestic pets and livestock can also be impacted if they contact water affected by an algal bloom. The toxins in Blue Green Algae cannot be removed through boiling the water, and if people believe they or their animals have been affected by Algae toxins, they should seek medical attention, council said in a statement.
Should residents notice considerable Blue Green Algae blooms that are of concern, they have been urged to contact council's environment team on 02 4934 9700.
