Snorkelers with Parks Canada have been hunting for Zebra mussels, the reason Clear Lake has been closed for the season, and they have been found.
During a survey, a live adult zebra mussel was found, as well as a partial shell.
This, along with environmental DNA in water samples, shows that this invasive species has indeed built a presence in the Lake.
The next step is to install an impermeable curtain around the boat cove and pier area to isolate the mussels from the rest of the lake.
Potash is being considered as a means to eradicate this invasive species, but this choice needs more testing and consideration of its environmental impact.
A technical briefing is scheduled for next week that will provide further detail on this situation, and the efforts going into solving it.
