There has been a breach in containment at Clear Lake.
Zebra mussels have been a looming threat to the lake throughout the summer, and the curtain containing them has been compromised.
Park canada has confirmed that strong winds created waves to push the containment curtain out of place.
Investigation is underway with Parks canada and their contractor to assess the repairs.
This containment curtain was installed at the start of August as an addition to the boat ban to prevent the spread of zebra mussels.
