The National Weather Service tweaked their forecast river levels for the North Fork Flathead River. They now show it cresting just above flood stage for about a day at the Canadian border in the Tuesday-Wednesday time-frame. It’s hard to know what will happen at Polebridge — the gauge seems to be broken again — but the river should at least be pretty close to bank-full by mid-week.
