The zebra mussel, an invasive species, has been present in Lake Memphremagog since 2017. Its proliferation is exponential, the situation is described as “uncontrollable”.
< p>An adult zebra mussel can lay between 30,000 and 1 million eggs per year. It is a small freshwater bivalve mollusc, according to the Ministry of Forests, Wildlife and Parks.
The zebra mussel has no natural predators and it is impossible to exclude it completely from a body of water once it has settled.
Thus, limiting its spread comes with a rather high bill for municipalities.
< p>A source of drinking water
The presence of mussels requires special attention, since 175,000 people drink water from Lake Memphremagog.
“In the city of Magog, we inspect more infrastructure, together with Sherbrooke, which is experiencing a similar situation. For the moment, it does not go beyond the plant,” explained Josianne Pouliot, coordinator in the environment division.
In Sherbrooke, we confirm that the increase in the number of zebra mussels is still increasing, but that its presence in city facilities is under control.
