Montana’s watercraft inspectors intercepted the 27th mussel-fouled vessel for the year. Last Sunday, vacationers traveling from Michigan to Glacier National Park with a kayak strapped on their van stopped at Nashua inspection station where inspectors found a zebra mussel attached to the kayak’s hull. The kayak had last been in Michigan’s Lake Cadillac, a known mussel-infested waterbody. Inspectors thoroughly decontaminated the kayak before sending the vacationers on their way.
