Marlène Thonnar holds up a handful of Eurasian water-milfoil plucked from the water of Lac des Trente et Un Milles.
He said that one of the main draws of the lake is the cleanliness of its water, and that too much overgrown vegetation could make boating difficult and drive tourists away. Carpentier hopes users of the lake will respect signs that may be installed to direct boaters away from the water-milfoil.The municipality has given a greenlight to a study into the health of fish populations in the areas affected by Eurasian water-milfoil.
To study the lake's fish population, the team will use a combination of traditional nets and an electrofishing technique that briefly knocks the fish unconscious, allowing researchers to collect the fish, identify, count and measure them, and then release them back into the water.
