Springtime in the Shuswap heralds a surge in outdoor water activities such as boating, paddling and fishing. However, this increase in watercraft traffic also brings a hidden danger: the potential spread of aquatic invasive species, including the notorious zebra and quagga mussels.
Originating from Europe, these mussels have wreaked havoc in places like the Great Lakes and parts of the U.S. Although British Columbia and neighbouring Alberta have so far escaped invasion, vigilance remains crucial.
“Zebra and quagga mussels attach to virtually anything submerged, from boat hulls to dock pilings. Once established, they’re nearly impossible to eradicate and require costly ongoing maintenance,” explains Erin Vieira, program manager for the Shuswap Watershed Council.
A recent economic impact report from the Province of BC pegs the potential cost at $129 million annually for B.C. residents and tax-payers.
These invasive mussels don’t just threaten infrastructure; “they degrade water quality and outcompete native species, putting our entire lake ecosystem and drinking water at risk,” Vieira adds. The presence of dead mussels can also spoil the natural beauty of shorelines.
Prevention is key and Vieira highlights a critical protocol: Clean-Drain-Dry. This involves cleaning all mud, plants and debris from watercraft after use, pulling the watercraft drain-plug and draining all water compartments thoroughly, and ensuring everything is dry before relaunching.
In addition, B.C. has implemented highway-side watercraft inspection stations managed by the B.C. Conservation Officer Service. “It’s mandatory for all travellers with watercraft to stop for inspections and possible decontamination, which is free of charge,” Vieira states. Ignoring this regulation can lead to a $345 fine.
Vieira also urges the public to educate others, especially visitors from outside the province, about these precautions.
“The more people who practice Clean-Drain-Dry and comply with inspection requirements, the better protected our waters are,” she says. Awareness is essential, as even a single infested watercraft could introduce a population of invasive mussels capable of causing extensive ecological and economic damage.
Anyone suspecting the presence of zebra or quagga mussels should report it to the Provincial RAPP line immediately at 877-952-7277.
