Last summer (2017) , Sheryl Jacson-Caron and a bunch of volunteers under the leadership of Vanesssa Nadeau from CRE Laurentides undertook a survey of aquatic plants on Curran Lake. They identified 18 species, more than in Clear Lake (10) but much less than on lake Louisa (25). A total of 44 species were found in the 44 lakes of Argenteuil surveyed so far.
None of these plants are exotic or invasive.
And as this map shows, plant density on Curran is low
These are the plants that were identified.
