What is being done to fix them?
In 2015, the City conducted a year long water quality study of the three lakes. An environmental consultant was hired to review the data and the findings were published in the Lake Bungana, Lake Brearley & Brickworks Lake, Maylands Environmental Report. Some of the suggested short and long term options were:
- Physical removal of algae and waste
- Reduction of phosphorus levels (Phoslock application)
- Extension of the lakes.
In February 2018, the City applied phoslock to the three lakes. Phoslock helps to minimise the re-release of phosphorous from the sediment back into the water.
Phoslock was applied to the lakes by boat and from the edge of the lake with a hose. The clay is white and this will give the lakes a milky colour for approximately two weeks as the clay settles to the bottom of the lakes.
