During the overnight period, cooler temperatures and precipitation resulted in no fire growth.


Working on the ground under the direction of the U.S. Northern Rockies Type 1 Incident Management Team (IMT), the initial attack teams from Banff, Kootenay and Grasslands national parks will continue extinguishing any hot spots that may be present. The U.S. IMT and Parks Canada are coordinating efforts and are in constant communication.

The forecast is looking favourable with cooler temperatures and precipitation in the form of rain with the potential for snow in the coming days. With this trend towards cooler weather and an increase in precipitation, Fire Managers are confident that there will be no significant fire growth within Waterton Lakes National Park.

As of 10:00 a.m. on Friday September 14th, 2018, the Bertha Lake Trail, and Bertha Lake and Bertha Bay Backcountry Campgrounds will re-open. The Lakeshore Trail beyond Bertha Bay Backcountry Campground will remain closed.


U.S. and Canadian fire managers have been responding to the Boundary Wildfire since it was first observed on August 23, 2018. Fire behaviour increased due to dry and windy conditions on September 7, 2018. That afternoon, the wildfire burned across the U.S. – Canada border and into Waterton Lakes National Park for the first time since the wildfire started.


Location: Boundary Creek Valley, Glacier National Park and Waterton Lakes National Park.

Size: Approximately 1,100 hectares (rough estimate until more accurate mapping completed)

Status: 14% contained, no growth yesterday.

Parks Canada Resources: one helicopter, three initial attack crews, local incident management team.


Waterton Lakes National Park and the Waterton townsite are open. The Bison Paddock overlook which includes road access to Horseshoe Trail remains closed to facilitate helicopter operations. Bertha Lake Trail, the Lakeshore Trail and the Bertha Lake and Bertha Bay Backcountry Campgrounds remain closed due to wildfire activity in the area.
