We regularly monitor blue-green algae and E. coli levels at lakes Legana, Illawong and Carramar, and will notify residents if these exceed the recommended standards.
Like any open body of water, the Quiet Lakes are impacted by the surrounding environment. Stormwater, nutrient levels, low water flows and warm weather can affect water quality, increasing blue-green algae (BGA) and E. coli.
Through flow options for Lake Carramar
Following the Essential Services Commission's (ESC) decision regarding Lake Legana and Lake Illawong, we advised that we would undertake an analysis and assessment of potential solutions to enable through flow to Lake Carramar. This is now complete.
Arrangements are being finalised to implement the solution for a trial period of two years, to ensure its effectiveness. Arrangements will be in place for this summer.
We will continue to monitor the lake for levels of blue-green algae over the summer months while the trial is underway.
