Threat of Invasive Mussels Continues as Domestic Travel is Encouraged

Invasive zebra and quagga mussels have been introduced into many water bodies in eastern Canada, but as yet, are not known in parts of Canada west of Manitoba. Increased domestic travel due to the pandemic could see many more infested watercraft traveling west and increasing the risk of infesting British Columbia waters.

“The only way to prevent the spread of invasive mussels is to make sure that every watercraft entering BC is inspected at a Provincial watercraft inspection station, which are run by the Conservation Officer Service,” said Sue Davies, Aquatic Coordinator for the Columbia Shuswap Invasive Species Society (CSISS), adding “so far this season watercraft inspection stations have intercepted 10 mussel fouled watercraft”.  We encourage Columbia Shuswap residents to talk to their out-of-province friends and family about the importance of watercraft inspection.

Invasive zebra (Dreissena polymorpha) and quagga (D. bugensis) mussels can travel as hitchhikers on watercraft due to their ability to attach to surfaces such as boat hulls and propellers, and to their tolerance for being out of the water for many days.  Invasive mussels can withstand up to 30 days out of the water and could easily survive the drive across country on either a trailered boat or a canoe.

The Provincial watercraft inspectors determine the risk level of the watercraft depending on where and when it was last in the water.  “If the watercraft is determined to be low risk, then the traveler is free to go; if it is high risk, travelers may be required to have their boat decontaminated, which is free to the traveler,” said Davies. “The consequence of travelers with watercraft not stopping at an inspection station is a swift fine, and the potential to destroy BC beaches, environments, and cost BC millions every year, so best to take the few minutes to stop in, and help prevent the spread of invasive species,” she added.

Provincial watercraft inspection stations are situated mostly along BC’s southern and eastern borders.  If a station is open, then it is mandatory for all travelers with watercraft, including paddleboards and canoes, to stop.

Travellers bringing watercraft to BC are encouraged to visit the provincial website,, and suspected invasive mussels should be reported to the Conservation Officer Service Report All Poachers and Polluters (RAPP) line at 1 877 952-7277.

The BC Government’s Invasive Mussel Defence Program is responsible for inspecting all watercraft entering BC and overseeing the invasive mussel lake monitoring program to sample waterbodies for invasive zebra and quagga mussels. Local invasive species societies like the Columbia Shuswap Invasive Species Society (CSISS) run outreach campaigns about how to prevent the spread of invasive species, and do much of the sampling of priority waterbodies in the Columbia Shuswap region as part of the Provincial lake monitoring program.  So far this season, the Province has reported that all samples tested to date for invasive mussels within BC are negative.  CSISS thanks the Province of BC, Habitat Conservation Trust Foundation, and the Shuswap Watershed Council for funding this important work.

Other aquatic invasive species such as Eurasian watermilfoil (Myriophyllum spicatum) and curly pondweed (Potamogeton crispus), are already present in some BC lakes.  Cleaning, draining and drying all watercraft when moving them between waterbodies will help prevent their spread within BC freshwaters.

The Columbia Shuswap Invasive Species Society is a non-profit organization dedicated to the prevention, management and reduction of invasive species in the Columbia Shuswap Regional District. CSISS is thankful for the generous support of the Habitat Conservation Trust Foundation, Shuswap Watershed Council, Columbia Basin Trust, the Columbia Shuswap Regional District, and the Province of BC.

The Invasive Mussel Defense Program has released a summer interim report.

So far 12,800 watercraft have been inspected, 74 of them were deemed high risk, and 10 were found to be mussel fouled.  Of the 10 mussel fouled watercraft, all but three were referred by other agencies, i.e. Canada Border Services, or inspection stations in Alberta, Manitoba, Idaho, or Washington.

K9 officers Kilo and Major continue to work at BC inspection stations, seeking out potentially infested watercraft.

Monitoring BC lakes for invasive mussels began in June.   227 samples have been collected and analysed so far, no mussels have been found.

August 15 th CSISS is hosting an educational booth at the base of Revelstoke Mountain Resort for the Revelstoke Wildflower Festival
August 11th and 13thCSISS is hosting an Invasive Plant Walk as part of the Revelstoke Wildflower Festival- See poster below and event schedule for details


Unlike these Western Painted turtles, CSISS employees are practicing physical distancing! Our highest priority is to ensure the health and safety of our workers and community, to achieve this we are following newly implemented safety protocols so we can safely complete field and outreach activities.
🌟 New Staff 🌟

Introducing our rockstar summer program assistant Kathleen Meszaros! 

Kathleen joined CSISS June 1st and has been primarily focused on supporting the aquatic program, completing boater outreach,  assisting with social media and completing veliger sampling.

Kathleen completed her BSc in 2017 and is currently in the MSc of Ecological Restoration program jointly at Simon Fraser University and the BC Institute of Technology. She has previously studied harmful algae blooms in the Pacific Northwest and has a keen interest in protecting our beautiful lakes and rivers.

Thanks Kathleen for all of your hard work!

CSISS staff are hard at work this summer! This video highlights some of the locations where our staff are completing aquatic and terrestrial surveys and monitoring of invasive species.
What’s new from our social media channels?
We have started two NEW weekly series for this season!
Every Wednesday look for our “What’s Flowering This Week?” post to share on our channels and local gardening and community group pages. Learn about native and invasive plant species, how to differentiate look-a-like species and how to choose native and non-invasive flowers for gardening.
Keep an eye out for “Invasive Catch of the Day” posts to learn about aquatic invaders. We share these with aquarium hobbyist and fishing groups on social media for targeted outreach.
Since last March, CSISS Outreach Coordinator Kim Kaiser has been creating Botanical Illustration videos of invasive plants. These videos highlight characteristics of specific invasive plants to aid in identification. Stay tuned for more videos on our instagram and youtube!
Aquatic Program Updates

The CSISS invasive mussel monitoring program is again sampling lakes across the region for zebra or quagga mussels to facilitate early detection. To date we have collected 47 samples from 10 waterbodies – Thanks to Habitat Conservation Trust Fund and Shuswap Watershed Council for their ongoing support.

Watercraft Inspection stations (run by the Conservation Officer Service) are operating this summer, inspecting and potentially decontaminating watercraft coming into BC to prevent the spread of invasive mussels and other aquatic invasives. More information on their program website:

Please report any suspected invasive mussels to the RAPP line on 1-877-952-7277. If you’re bringing your boat from out-of-province, stop at a Watercraft Inspection Station or contact the Provincial Mussel Defense Program at to determine if your boat is HIGH-RISK and should be decontaminated for possible zebra or quagga mussel presence before accessing B.C.’s lakes and rivers. It’s free! Do not launch the boat into any B.C. waters until you have received instruction from a B.C. Provincial Aquatic Invasive Species Inspector. 

See the Shuswap Watershed Council’s 2019 Water Quality Report for information about invasive mussel sampling, Asian Clam and Eurasian Water Milfoil in the Shuswap.
Summer, is that you?

Rain or shine, CSISS terrestrial field staff are happy to have their boots on the ground, completing invasive plant inventories, treatment monitoring, and responding to invasive plant reports.
