Environment and shoreline

In concert with it’s mission adopted along with it’s constitution in 1990, and conscious of the fragility and the degradation of it’s shoreline in several areas, the Association has, for some time, undertaken many efforts to improve the condition of the shore.

Longstanding involvement in the protection of the shoreline

Rives1

The maintenance of an undisturbed shoreline strip is one of the factors that improve the water quality, and wildlife habitats, around the lake.

It is because rain water runoff is slowed by roots, branches and trunks, that it is filtered before entering the lake. The shoreline strip is the last filter for runoff before it enters the lake.  It is also the last buffer against waves and erosion if it is made up of flowering plants, trees and shrubs.

A lush shoreline strip imparts a natural character to the environment, and increases property values.

Protection of the shoreline and its watershed
  • Regeneration of the shoreline

The Association du lac Mercier is aware of the importance of the problem of erosion around the lake, and the need to improve the quality of shore. During the summer of 2010, the town of Mont-Tremblant has inspected the shore  and make recommendations so that each owner complies with the new regulations on the shoreline, adopted in January 2009 (Regulation 2008-102).

Where shoreline regeneration is required, some native plants are particularly successful in naturalization of shorelines. These are pioneer plants well adapted to our climatic conditions, including ease of reproduction and resistance to manipulation.

Some good choices for this purpose are: alder, dogwood, sweet gale, the vine virgin, willow and spirea shrub with large leaves.

Hereunder are the pictures of a few varieties that are recommended:  “Myrica gale” also called “Sweet gale”, growing 1 meter high, very resistant, tolerates being flooded during long periods and spreads easily.

The Bayberry Balsam is also called “wood-feels-good”, meaning its generic name besides “fragrance.” This shrub reaching 1 m high spreads very easily (seeds), is well adapted to our climate, may tolerate prolonged flooding and grows in poor environments (sandy banks) which makes it an ideal shrub for shoreline recovery.

Rives2 (2)Which plants are recommended for shoreline restoration (FR)

Since Summer 2012, there has been a remarkable re-growth of vegetation along the shoreline.

Efforts at reforestation are quite visible on most lakefront properties.

According to the Quebec Court of appeal, municipalities can oblige landowners to restore the shoreline to it’s natural state.

Small trees for planting

résineux    feuillus

May 2017: In collaboration with AGIR  pour la Diable, our members were offered small trees for planting at no cost.  More than 150 small trees have been distributed.

 

  • Erosion of the shoreline :

 Lac Mercier is especially vulnerable, because more than 50% of it’s shoreline lies adjacent to the linear park.

It is crucial to preserve as much as possible, the natural vegetation along the Linear Park.

PL14.1

The Association collaborated with the Regional Municipality and AGIR pour la Diable during Summer 2012, in the anti-erosion reforestation efforts applied to several portions of the shoreline.

  • Construction bordering the lake and development in the watershed

Several housing projects have gradually altered the appearance of the watershed of lac Mercier.

Recall of past activities related to the development in the watershed

Conscious of the environmental impact of these major projects on the shoreline and the water quality, the Association remains vigilant in order to minimize any negative impact.

We are advising our councillors so that the lifestyle character of the village sector is not lost in a maelstrom of urbanisation.

  • Short-term tourist lodging:

In order to reduce the negative impact of a variably  changing clientele in a very desirable sector,  we support the new City regulation prohibiting short-term ( less than 31 days) tourist residences  along the shoreline of lac Mercier.

Illegal rentals

 

  • Construction in the lake’s protected zone:

The City of Mont-Tremblant has recently modified the regulations relating to minor variances, so that all construction in the protected zone of the lake is prohibited. Going forward, no permits will be granted for minor variances or new construction, within the protected zone.

  • Docks

The installation of a dock can may degrade the water quality and disturb aquatic fauna. It is essential to take the necessary measure to protect the environment.

No permit is required to install a dock, but certain regulations must be respected.

Here is a summary of the City regulations that pertain to docks.

  • Roadways around lac Mercier

Because of the increasing number of cyclists now using the chemin du lac Mercier, the Association has asked the City to install warning signs indicating a reduction in the speed limit, and begin planning for widening of the road  to allow safer passage for cyclists.

We were finally able to have a paved cycling path created on the east side of the chemin du lac Mercier during Summer 2013. The speed limit was also reduced to 60 km/h in 2015.
