    The contaminated boats were discovered at the Dunmore vehicle inspection station southeast of Medicine Hat and the Vermilion station 200 kilometres east of Edmonton.

  • “Alberta is being very proactive in taking steps to stop invasive mussels from entering our lakes,” said Environment and Sustainable Resource Development Minister Robin Campbell in a release.

    “Our success really depends on boaters taking advantage of inspection sites and always cleaning, draining and drying their boats. With only about half of boaters stopping to have their watercraft inspected this summer, stricter measures may be necessary to protect our waterways.”

    An infestation in Alberta would cost an estimated $75 million annually, the province said. 

    “One of the contaminated boat owners admitted he was very thankful for the inspection station, as he wouldn’t want to be responsible for bringing mussels into an Alberta lake,” the province said in a release.

    Earlier this summer the province said it was deploying sniffer dogs at checkpoints near lakes and rivers around the province in a bid to prevent an infestation of zebra and quagga mussels in Alberta.

    The fingernail-sized freshwater molluscs get attached to boats and can choke out native species and clog water intake pipes and machinery once they get established.

    Quagga mussels arrived in Canada and the United States from Europe in the 1980s. Along with the closely-related zebra mussels, they cost governments in Eastern Canada and many U.S. states millions of dollars per year.

A boat overrun with invasive mussels was intercepted by Alberta’s watercraft inspectors before it made it into Sylvan Lake on the May long weekend.

It was discovered during one of the mandatory inspections, which started over the weekend on highways coming into Alberta and at lakes across the province.

“It was amazing,” said Cindy Sawchuk of Alberta Environment and Sustainable Resource Development. “It’s scary, also.“It had mussels on it.”

The owner, who had bought the boat in Ontario, was about to launch it at the Sunbreaker Cove launch at Sylvan Lake when the inspectors found the mussels.

He was fully cooperative and the boat will be decontaminated by the province’s specialized teams.

Sawchuk said it was one of 269 boats inspected on the May long weekend for the invasive mussels.
