Whirlpool Lake and campground in Riding Mountain National Park have opened to the public for the season.
Parks Canada says there is no evidence of zebra mussels in the water after a year of diligent monitoring for the species.
The campground is open for self-registration, while the water will be accessible to paddlers as the season unfolds.
Those who wish to use park waters must have all watercraft (including canoes, kayaks, paddleboards, and flotation devices) inspected through Parks Canada’s mandatory inspection for aquatic invasive species. The service is free of charge and watercraft passing inspection will receive a permit from Parks Canada watercraft inspectors.
