Zebra mussels & boat stickers

The municipalities around lake Massawippi have adopted common by-laws to prevent the infestation of lake Massawippi by the zebra mussel. Lake users must get a seasonal boat sticker (or daily for one time visitors), to have their boat washed before going into the lake.

The cost of the seasonal boat sticker is established each year. Here are 2022 rates:

For residents

Motor boats $40 for the first one and $25 for all others

Non motorized boats 5 $ each

For non-residents

Motor boats $350 each

Non motorized boats 5 $ each

The by-law requiring a boat sticker and by-laws relating to security are enforced by the lake patrole (Patrouille nautique). The patrol usually included a few officers for the summer season.

Boat Sticker are available at the following Town Halls: 

Ayer’s Cliff

Canton de Hatley
