Invasive species are a major concern in the Gatineau. A number of lakes are infested with Eurasian milfoil. The municipalities of Blue Sea and Messines recently made boat pressure-washing mandatory (see the story), and Lac Sinclair has a boat-washing program. Here at Lac Mahon, there is no public access, and our Boater`s Code provides that

• • Before launching I will thoroughly wash my boat, well away from the lake.

  • If I allow someone to launch a boat from my property, I will make them aware of this Boater’s Code.
