Here are some of the biologists' observations and solutions:

Water: Lake Tremblant is oligotrophic, or relatively healthy.

Recommendations:

• Monitoring of its phosphorus and chlorophyll A concentrations, transparency levels, and the risk of invasive plant introductions must continue.

• The LTA will continue water quality monitoring (RSVL) and enforcement of watercraft washing regulations, together with the PLTN Marina.

Shoreline buffers: The overall quality of the riparian buffers is good, despite deforestation and the increased presence of multidwelling developments.

Recommendations:

• Establish a fund for the purchase of targeted land (nature reserve)

• Restoration and re-vegetation in compliance with Muni regulations.

• Maintain the riparian strip, the floodplain and the shoreline vegetated with native species appropriate for these environments.

Wastewater: It is important to monitor septic systems and the presence of unsuitable soils to avoid indirect contamination of the water through the discharge of harmful sediments such as sand, salt and other pollutants.

Recommendations:

• One of the by-products of COVID is that vacation homes are used more frequently by more members of families, hence septic systems should be inspected more frequently, rather than four-yearly.

• Sediment ponds should be obligatory at all commercial shoreline facilities to capture sand, salt and other pollutants.

Protection of the fauna and flora of Lac Tremblant :

Recommendations:

• Reduce human intervention to a minimum in the shoreline, floodplain and littoral zone

• Each citizen and their contractors along the shoreline ensures that projects to be carried out along the shoreline and the littoral respect the best environmental and wildlife practices

• Awareness work to find alternative solutions to road salt around the lake (e.g. Eco-road)

• Raise awareness for the protection of fish habitats. Search for subsidies to supervise the seeding of smelts by volunteers (seeding planned for a period of at least three years). The objective is to avoid the introduction of disease

Education, awareness and communication:

Recommendations:

• Pursue any acquisition of knowledge related to the lake, the hydrographic environments and the various impacts on them, and/or in connection with any relevant point, including those mentioned above, in order to have a background that will ensure a better guideline in the collaborative future of the concerted plan.

• Ensure that boating safety in general is well taught in order to avoid and/or reduce the impacts of erosion of the shores of Lake Tremblant.

• Make a request, if applicable, that the nautical police of the Sûreté du Québec be available to provide training in this regard to boaters on an annual basis. Make landlords aware of certain problems directly related to short-term rentals (think in this case, among other things, of the increase in waste generated by this type of rental).

• Make landlords aware of certain problems directly related to short-term rentals (think in this case, among other things, of the increase in waste generated by this type of rental).

• Promote and advocate the eco-responsibility of tenants in order to provide for better management of waste and residues on the part of the latter by simply adding a sentence to this effect in any residence advertisement offered for rent on any platform such as, or similar to, AirBnb (such as, for example, being able to bring back returnable containers, or to make good use of the ecocentre, by providing any relevant information on the various services offered nearby, etc.).

• From a communications point of view, not only is it essential to promote membership in the Association, but it is also essential that a section on lake protection awareness be added to the monthly newsletters at each edition.

• One of the repercussions of Covid-19 is that we have been able to see more and more family members enjoying their second homes more frequently, which inevitably makes it more than wise to inspect septic tanks more regularly than usual, instead of just once every four years.

• Sedimentation ponds should be mandatory at any commercial location along the banks to capture sand, salts and other unwanted pollutants.

• Carry out awareness-raising work to find alternative solutions to the use of road salts on the outskirts of the lake (as could be for example an "Eco-road", etc.)
  
  As you can see, this LACtion process has identified opportunities for harmonization of regulations between adjoining municipalities and issues of compliance with municipal and provincial environmental regulations. It also highlights the importance of community involvement in preserving the environment.
