Glacier National Park personnel continued to monitor and respond Friday to problems created by recent heavy rains.

The North Fork area received over an inch of rain in one hour on Tuesday night, and rain continued the rest of the week throughout the park.

High winds and the rain have caused downed trees, debris slides and localized flooding. More impacts are being discovered in the backcountry, where park employees have been busy clearing downed trees off of trails.

The Apgar and Fish Creek areas sustained the most damage from downed trees. The roof of the backcountry permitting office in Apgar sustained damage after being struck by a falling tree.

The Cracker Lake Campground was temporarily closed Wednesday because of flooding. In the North Fork, the Upper Bowman Creek Bridge was washed out.

On the east side of the park, heavy runoff caused a rapid rise on Swiftcurrent Lake in the Many Glacier Valley. That prompted sandbagging efforts at the bridge over the lake’s outlet. The bridge is the main access to Many Glacier Hotel.

Trails in the Many Glacier, Belly River and St. Mary areas sustained flooding damage, but the extent of the impacts is not yet known, according to the park.

To the north, Waterton Lakes National Park in Canada has been experiencing similar and even more severe problems.

The Akamina Parkway is closed indefinitely due to a washout near the McNealy’s Day Use Area.

Red Rock Parkway and roads on the Blakiston Fan and in the Upper Compound are closed due to flooding.

Northwest Montana river levels rose sharply with the heavy rainfall.

The North Fork Flathead River at the Canadian border rose 3 1/2 feet from Wednesday to Thursday, cresting at flood stage of 10.5 feet. The river level dropped a foot on Friday.

The main Flathead River at Columbia Falls also rose 3 feet but crested a foot shy of flood stage on Thursday before beginning to drop.
