Parks Canada is protecting Waterton Lakes National Park’s aquatic environment from invasive mussels by prohibiting the use of power boats and trailer-launched watercraft in the park.

Invasive mussels were detected in Montana less than a half-day’s drive from Waterton - in the fall of 2016.

Invasive mussels pose a significant and irreversible threat to the park. Visitors can still use human-powered watercraft, such as canoes, kayaks and paddleboards in the park, after completing a mandatory self-inspection form.

Although the decision will remove an activity that has been part of the Waterton experience for decades, it is necessary given the serious threat to the park’s lakes, rivers and streams and downstream resources.

It is critical that Parks Canada take this action now to minimize the risk posed by invasive mussel contamination. Once invasive mussels are introduced, they are impossible to eradicate and their effects are irreversible. By working together we can help protect our waters.
