Clean, Drain and Dry | Parks Canada

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.

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

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

Dry: minimum 48 hours after use in B.C., Alberta, or Canadian territories, including in the national parks AND minimum 30 days after use in the U.S. or provinces other than B.C., Alberta and/or the Canadian territories.
