Going batty to save lakes

BAT boxes, granules to suck up phosphates, revegetation, and mechanically skimming algae from Brearley and Bungana lakes have been suggested to decontaminate water in Maylands’ lakes and combat mozzies.

A full water quality report was presented to about 70 concerned locals at Bayswater’s Rise last Monday, who heard long-term restoration of the lakes might cost $3 million.

• A raft of initiatives have been suggested to combat poor water quality at Maylands’ lakes, but getting residents to ease up on fertilisers remains a major obstacle.

Dredging

Dredging the two lakes and modifying their shape; installing floating wetlands and submersible solar pumps; and funding community education were some of the report’s expensive management recommendations for the long term.

But the report said ratepayers could also do their bit by limiting fertiliser use and maintaining clear gutters to keep stormwater clean. Dumped rubbish, grass clipping and pet fish were also problems they could help combat.

The report was funded by Bayswater council last year following concerns about water toxicity. The recommendations will have to come to council before being put into action.
