Protecting the Lake
The PLTN board remains very concerned with the risk of aquatic invasive species contaminating our lakes. Of the roughly 20 plant species in Québec considered invasive, the predominant threat is from myriophylle (Eurasian Milfoil) which has already contaminated 46 surrounding lakes in the Laurentians including Supérieur, Mercier, Ouimet, Barkmere, Labelle and Lac Carré.
With no known predators this plant spreads very quickly, absorbing much of the oxygen and over-taking a lake and its biodiversity. Once established it is virtually impossible to eliminate and can only be managed with very costly efforts.
Environmental Watershed Study
Your Board has been informed of a new initiative by l’Organisme des Bassins Versants des Rivières Rouge, Petite Nation et Saumon (OBV RPNS) to study the impact of the dams within this water system, including the dam at the south end of Lac Tremblant.
If you have an interest in participating or contributing, please contact our PLTN secretary.

PLTN would like to present new electronic technologies that can be used as a cleaner option for our lakes.
Eurasian Milfoil Information
With no known predators this plant spreads very quickly, absorbing much of the oxygen and over-taking a lake and its biodiversity. Once established it is virtually impossible to eliminate and can only be managed with very costly efforts. It has significant impacts on the lake, including:
- Negatively impacts swimming
- Restricts boat navigation
- Fish populations diminish
- decreases food supply
- decreases size and number of fish
- interferes with spawning.
- Property values likely to drop (Lac a la Truite residents claiming 50% devaluation)
- Can prevent natural water flow
- Can grow far from shore, up to 10m depth.
- Impact on tourism, Ironman event, local businesses
Nearby Lac Superior has been dealing with this for over 10 years. In an effort to control it, the population voluntarily shut down all boat traffic on the lake for 3 years. They were unable to eliminate the Eurasian milfoil.
