Protect your Lake from Eurasian Watermilfoil: wash all boats!

This exotic and very invasive plant –   Eurasian Watermilfoil – has already spoiled more than 40 lakes in the Laurentians alone. Fortunately, there is none in Argenteuil. None in our lakes.

We absolutely want to keep it that way because once a lake is contaminated, little can be done to restore it.

I have raised his issue before but I am writing again about it because it is now our biggest threat!

So, this summer, make sure that the boats brought in by renters and friends – and yours if it is used in a foreign lake – are thoroughly washed before they navigate your lake.

Same applies to paddles, fishing gear, electric motors.

Here is how to proceed.

Follow these four steps: inspect – drain – clean – dry

Inspection is the most important. If you look carefully, you will probably locate exotic plants or molluscs. Drain to make sure the is no leftover water at the bottom of your kayak, for example. Clean with fresh water and a bit of bleach. Finally, let dry in the sun for a few days.

All this should evidently be done at a good distance from the lake.

    Important reminder. The problem is so intense on some lakes that property values went down dramatically. Thanks Jacques for keeping us on our toes.

    Jacques, thanks for the reminder. we can all do better with our boats. and especially to help educate the new people who rent cottages on our lakes.

    Maybe the DCA should have a renters checklist that we include on the website?

    An interesting idea, Michael. I will explore it further.
