Waterton takes action to prevent spread of aquatic invasive species

Parks Canada, including Waterton Lakes National Park, is continuing to take action to prevent the spread of zebra and quagga mussels, whirling disease and other aquatic invasive species. Watercraft and angling restrictions are in effect for this year.

Waterton is the headwaters of the Waterton River, which feeds into the broader Oldman and South Saskatchewan watersheds. It is critical all residents and visitors continue to take the threat seriously and take action to reduce the spread. 

Non-motorized watercraft (kayaks, canoes, paddleboards, etc.) from outside Waterton Lakes’ boundaries remain prohibited from launching in park waters. The prohibition on outside watercraft, introduced in 2024, has been more effective in reducing the likelihood of AIS transmission than previous programs. 

The risk of AIS introduction remains high, and as a result Waterton Lakes’ non-motorized watercraft restrictions will continue.

Watercraft rentals for visitors will be available from local businesses. 

Parks Canada is committed to accessibility and will permit adaptive paddling equipment for those who require it, with conditions. 

Users whose watercraft remain inside park boundaries can once again apply for a seasonal permit. These users must take a short course on AIS and have their watercraft inspected by Parks Canada. 

This year, angling will again be permitted in some flowing waters in the Waterton River watershed, including Cameron Creek and the Waterton River. 

Water levels and temperatures will be monitored park-wide, and drought-related closures will be issued if required.

Unfortunately, whirling disease was detected in nearly all fish sampled in the Belly River in 2024. The Belly River and its tributaries will remain closed to angling in 2025.
