Lac Sauvage (Wild Lake) is surrounded by public forests to the South and by the CTEL (Centre Touristique Éducatif des Laurentides) to the East. Lac Sauvage is located in the municipality of Saint-Faustin-Lac-Carré, which is part of MRC des Laurentides.

The mandate of APELS is to protect the aquatic environment of the lake and the forests surrounding it.

There are 80 members in the association and 70 of them own a cottage on the lake or are residents at the lake.

Since 1988, APELS publishes a quarterly newsletter, "Le HUARD" with the objective of sharing local news and increasing the awareness of its members to environmental questions.

APELS is a member of:

• RAL, that regroups 10 lake associations, similar to APELS, in the region of Saint-Faustin-Lac-Carré
• CRELA, Environmental regional council of the Laurentians.
