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-related gear before entering a new waterbody
Clean
all mud, sand, plant, and animal materials from your watercraft, gear, and angling equipment.
Drain
all watercraft, gear, and angling equipment before leaving the waterbody.
Dry
for at least 48 hours when last used within AB, BC, NWT, or YT; and at least 30 days when last used outside of AB, BC, NWT, or YT.
Certify
watercraft, gear, and angling equipment by visiting a Parks Canada inspection station or obtaining a self-certification permit.

[Two people tip a canoe onto its side; water is emptied from a canoe on its side.]
Text: Drain coolers, buckets, compartments and other items that may hold water on land before leaving the waterbody.
[A paddle is pulled apart and emptied of water.]
Text: Some aquatic invasive species can survive in pools of water for 30 days.
[Two people stand a paddleboard up against a tree.]

How to certify
In most of the mountain national parks, an Aquatic Invasive Species (AIS) Prevention Permit is required to access waterbodies with any watercraft, gear, or angling equipment. The type of AIS Prevention Permit required is dependent on the park and the type of watercraft or gear. See below for current mandatory permit requirements.
Mandatory AIS prevention permitting requirements in the mountain national parks for 2024:| Motorized Watercraft | Non-motorized Watercraft | Angling equipment and other gear | |

The Self-Certification permit and watercraft inspection stations are available at the following locations:
Banff National Park
Watercraft Inspection Stations:
- Lake Louise Inspection Station: Located in the Lake Louise overflow parking lot approximately 7 km southeast from the town of Lake Louise on Highway 1
- Lake Minnewanka Inspection Station: Located along the Minnewanka Loop Road, approximately 6 km northeast from the town of Banff
Self-Certification Permits are available at the following locations:
- Kiosks located at waterbody access points and trailheads

Jasper National Park
Kootenay National Park
All waterbodies are closed
To prevent the spread of whirling disease, all waterbodies in Yoho and Kootenay national parks are closed to watercraft and angling until March 31, 2025.
This closure is necessary to protect vulnerable fish populations and sensitive ecosystems from aquatic invasive species. There is no treatment for whirling disease. Once established, it is very difficult to eradicate. Protect park waters — respect all closures.

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.

Whirling Disease
Whirling disease is caused by a parasite that affects trout, whitefish, and salmon. The parasite develops in a fish’s skull and spine, resulting in skeletal deformities, difficulty swimming, and a dark or blackened tail. The parasite can be spread in mud and water on watercraft and waders. This disease is not harmful to humans or other mammals but can have significant effects on trout, whitefish, and salmon populations. -
Invasive mussels
Quagga and zebra mussels are small, fan-shaped species, that range from dark brown to white in colour. They are very efficient at filtering nutrients from the water, limiting food for native species. Dense colonies of mussels can clog water pipes, damage boats and infrastructure, and make shorelines and beaches unusable. Quagga and zebra mussels are often transported unknowingly to new waterbodies on boats and recreational equipment. New recent invasions have occurred in Manitoba and Idaho. -
Eurasian water milfoil
Eurasian water milfoil is a perennial, submersed aquatic plant native to Eurasia and North Africa. Eurasian water milfoil forms thick stands that shade native plants, decrease oxygen levels as they decay, and impede boating and swimming. New colonies can form from a single stem, seed, or leaf that can easily be spread attached to a watercraft, waders, or other gear.
Report aquatic invasive species sightings:
Email ReportAIS-SignalerEAE@pc.gc.ca with a description of the organism, photos, and a precise location (GPS coordinates preferred).
Sightings outside of the national parks can be reported to:
