The Marl Lake Ratepayers Association is pressuring Brockton Council to approve a fertilizer ban soon.
The proposal is for all inland lakes -- such as Marl Lake and Lake Rosalind -- to avoid last summer's problems with blue green algae.
Vice President Rick Katie says until that bylaw is passed, some lake resident will continue to fertilize and spray their lawns.
It's believed the fertilizer was responsible for the blue green algae problem last summer.
Katie admits it's frustrating the only way to stop residents is through a bylaw.
Brockton Council has vowed to have the bylaw ready by September or October.
A public meeting will first be held to provide residents as well as those in the fertilizer industry a chance to voice their opinion on the matter.
Katie says a strong public education effort has more and more lake residents changing their lawn care practices to be 'green' friendly.
Last summer Marl Lake and Lake Rosalind underwent a ‘Do not use, bath or swim’ ban due to the blue green algae problem which was linked to lawn care fertilizer.
