The Shoreline is an ecologically sensitive zone where the water meets the land.  Over 90% of the species in the lake either live in or pass through this zone.  Vegetation along the shoreline acts as a filter for pollutants, preventing them from entering the water.  Shrubs also act as a binding agent to prevent erosion.  Protecting this zone is critical in maintaining a healthy lake.  The municipality has passed régulations to protect this zone.  You can do your part to help preserve our shorelines.


The protection and preservation of our shorelines are key to the long term survival of our lakes, our watershed, and our ecosystem.

The Council of the MRC de La Vallee-de-la Gatineau has adopted a by-law that outlines the requirements to ensure the ecologial sustainability of our waterways, and maintaining or improving their quality through establishing adequate measures for shorelines, littoral zones, and floodplains.

The shoreline in brief:

The bylaw defines the shoreline as a strip of land bordering an aquatic zone and or a watercourse that extends inwards on the land from the high water mark. The width of the shore to protect is measured horizontally. The lakeshore or riverbank is at least 10 m wide where: the slope is less than 30%; or the slope is greater than 30% with a bank less than 5 m high. The lakeshore or riverbank is at least 15 m wide where: the slope is continuous and greater than 30%; or the slope is greater than 30% with a bank over 5 m high.

The shoreline also includes a band that extends from the water’s edge to roughly where sunlight no longer penetrates to the lake bottom.

Simply, this means that the regulations pertain to the 15 meters of land from where the water’s edge (depending on the slope) extending into the water where the sun no longer illuminates the lake bed.
