Conservation officers discovered zebra mussels on a boat inspected at Blackstrap Provincial Park, prompting an immediate quarantine, decontamination and criminal charges against the vessel owner, the provincial government said.
Inspection stopped a potential infestation
Officials said the boat had recently been in Lake Ontario when it arrived in Saskatchewan. Officers, working in co-operation with the provincial Ministry of Environment, implemented a quarantine order before the vessel entered any Saskatchewan waterway.
The vessel was decontaminated and placed under an additional 30-day quarantine, the news release said. The boat owner, described as an Ontario resident, was charged with transporting a prohibited species.
"Watercraft inspections are critical to ensuring Saskatchewan's waterways are protected from the spread of aquatic invasive species," Environment Minister Darlene Rowden said in the release.
Why the discovery matters
Zebra mussels are a highly invasive aquatic species that can attach to infrastructure, outcompete native species and alter ecosystems. Once established in a waterbody, they are extremely difficult, if not impossible, to remove.
Community Safety Minister Michael Weger highlighted inspections as more than regulation, calling them "one of the most effective tools we have for stopping aquatic invasive species from entering and damaging Saskatchewan's waterways."
- Boat recently travelled in Lake Ontario — origin of contamination.
- Decontamination completed, followed by a 30-day quarantine.
- Owner charged with transporting a prohibited species.
What watercraft owners must do
The province reminded boat owners to follow responsible practices and the Clean, Drain and Dry guidelines. Conservation officers will continue inspections throughout the summer and into early fall, and anyone transporting a watercraft is required to stop at open inspection stations.
| Action | Reason |
|---|---|
| Stop at inspection stations | Prevents contaminated vessels from entering waterways |
| Decontaminate equipment | Removes aquatic invasive species |
| Observe 30-day quarantine | Ensures no surviving organisms remain |
The discovery at Blackstrap underscores that invasive species continue to be transported between jurisdictions on equipment and vessels. Provincial officials urged diligence from boaters and travellers to reduce the risk of introducing zebra mussels and other aquatic pests to Saskatchewan lakes and rivers.
Conservation officers will maintain a presence at inspection stations for the remainder of the season. The province said anyone transporting a watercraft must stop at open stations to allow inspections and to help protect local ecosystems.
