It was another successful year for keeping invasive mussels out of Alberta’s waterways.

Alberta Environment and Parks says,  in 2018 inspectors looked over 31,000 boats and watercraft at inspection stations across the province, finding mussels on 11 vessels.

The Dunmore Weigh Station has been one of those locations boaters must stop at since the program began.

Officials say testing of waters in the province continue to show no invasive quagga or zebra mussels in any lake, river or stream.

Previous estimates indicate it would cost the government around $75 million annually should an infestation occur in Alberta.
