Floating islands bring big benefits to lake

Following the success of a floating island in Subiaco Common Lake last year, the City will install two additional islands in January.

As well as providing somewhere for local fauna to roost and nest safely, it will naturally improve water quality by filtering water through the roots of the plants, reducing the risk of algae blooms.

The additional islands will also contribute to the overall aesthetics of the popular park and, in time, look like a natural feature of the lake.

They are made up of a base structure supporting native semi-aquatic plants, enhancing biodiversity in the area.

Mayor David McMullen said the first floating island was well received.

“We know our community cares about sustainability – in all its forms – so the first island was very well received and many people have spotted wildlife making good use of it to nest and rest,” he said.

“I’m looking forward to seeing the same with the additional islands which will also further improve the water quality in a natural and sustainable way.”

The City will also be installing fish traps in the lake in the first half of 2022 to remove feral carp and koi fish which negatively impact on water quality and compete with native fish.
