Blue-green algae warning

In early November 2020, a slick of Blue-green algae (cyanobacteria) was found in the island bay (near Ch. Corbei). Cases like this sometimes happen in the late fall. The cold temperatures cause the bacteria to float to the surface and collect into clusters. Our assisting biologist Paul Hamilton identified it under the microscope and advises us:

Water testing results

The Association tests samples of water from the Lakes for phosphorus, nitrogen and E-coli on a regular basis. Volunteer and Lake Association member Carole Doré has collected samples for testing for over 15 years. Say Thank You when you see her!

Eurasian Milfoil - keep your boats out of the Zombie Weed

Some years, invasive Eurasian Milfoil forms a dense carpet on the lake's surface, crowding out the indigenous plant species and harming fish. It was brought in on someone's boat or fishing equipment in the 1990's. It's a Zombie Weed: each tiny piece broken off by waves or boats can turn into a new plant. Avoid areas marked with yellow buoys that mark milfoil close to the surface.

Certaines années, le myriophylle envahissant forme un tapis dense à la surface du lac, évinçant les espèces végétales indigènes et nuisant aux poissons. Il a été introduit sur le bateau ou l'équipement de pêche de quelqu'un dans les années 1990. Chaque petit morceau brisé par les vagues ou les bateaux peut se transformer en une nouvelle plante.

Canada Goose Action Plan

An adult goose can produce as much as a kilo of poop every day, and those droppings can contaminate our water - and your property. 6 more geese hatched at the lake in 2020, thankfully fewer than in 2018 and 2019.
