With the assistance of Melbourne Water, we conducted water quality testing at four principal sites in the Park between 2008 and 2019. We tested for dissolved oxygen, pH, water temperature, salinity, turbidity and phosphate.
Our lakes are not fed by any natural watercourse and nor is there currently any discharge so in dry periods water levels drop and salt and nutrients become more concentrated.
We hope to secure runoff from nearby sites to bring more water into the Park and to create a more natural system of outflows to maintain water quality.
