Protect park waters: preventing aquatic invasive species

Aquatic Invasive Species (AIS) are non-native plants, animals, and diseases. Many AIS are harmful to freshwater ecosystems. AIS reproduce quickly, rarely have natural predators and often out-compete native freshwater species.

Waterton Lakes National Park

Beginning April 1, 2024: all non-motorized watercraft from outside of the park are prohibited from entering waterbodies.

Yoho and Kootenay national parks

Until March 31, 2025: All waterbodies are closed to watercraft and angling to prevent the spread of whirling disease. This closure is necessary to protect vulnerable fish populations and sensitive ecosystems from aquatic invasive species.

Clean, drain, dry, and certify all watercraft and water gear before entering a new waterbody



all mud, sand, plant, and animal materials from your watercraft and water-related gear.



coolers, buckets, compartments, and other items that may hold water on land before leaving the waterbody.

Aquatic Invasive Species of concern

Aquatic invasive species (AIS) are non-native plants, animals, and diseases. Many AIS are harmful to freshwater ecosystems. AIS reproduce quickly, rarely have natural predators and often out-compete native freshwater species. Preventing aquatic invasive species from entering waterways is a Parks Canada priority. Once AIS are established, removal is next to impossible.

Report aquatic invasive species sightings

Take a picture, note the location, and send it to

Sightings outside of the national parks can be reported to: 1-855-336-2628 (BOAT) in Alberta and 1-888-933-3722 in British Columbia.
