Glacier Anglers's Tip of the Week

The river has been steadily dropping, settling into normal river levels for this time of year. However, remember that it's wintertime, and the Middle Fork cutthroat trout are wintering in their tributaries, which are off-limits. You can often find them at the mouth of the tribs, during warmer days--just be sure that you're in the river, not the tributary.

5-Day Outlook as of 1/12/26

This week the sun will be out, with air temperatures above freezing; even into the mid-40s, so we may see bwo's popping off in the slower, deep runs, especially near tributaries.

Techniques & Tips as of 1/12/26

Remember that trout don't like to move in super cold temperatures, so you'll need to get your nymph right in front of their noses. If they are rising, keep the fight short so they don't expend too much energy.

Description: About Middle Fork Flathead River

The Middle Fork of the Flathead River originates in the heart of the Great Bear Wilderness in one of the most remote and pristine areas in the lower 48. Once the river reaches Hwy 2, just west of Marias Pass, if flows westward, following the highway and making up the majority of the southern boarder of Glacier National Park until its confluence with the North Fork near Blankenship Bridge. The Middle Fork is a true Jewel, with excellent West Slope Cutthroat fishing along its entire length.
