On July 17, 2024, while conducting a visual survey, Parks Canada snorkellers found a partial shell and one living, adult sized zebra mussel attached to a rock.
Water samples collected from Boat Cove from June 19-27, 2024, have also tested positive for environmental DNA from zebra mussels. This evidence shows the invasive zebra mussels are building a presence in Clear Lake.
Parks Canada remains highly focused on the next steps as staff take actions to prevent the spread of the aquatic invasive species.
