For Hepburns Lagoon the warning was issued on January 9 and remained in place for 238 days.

GMW Water Quality coordinator Bianca Atley said GMW would keep testing for further changes to blue-green algae levels at its storages.

"We will continue undertaking water quality monitoring and if blue green algae reach levels deemed unsafe by national health guidelines, a warning will be issued," she said.

Ms Atley said the removal of the warnings was a welcome boost ahead of the upcoming school holiday period."

Our storages are a great place to visit and being able to remove these warnings means people can enjoy them to their full extent," she said.
