Glacier Anglers's Tip of the Week

Most of the river access points are relatively clear of snow and ice, so head to put-ins near tributary mouths where fish will be moving. Remember, tributaries are off-limits until the third week of May, so stay in the main river near the tributary mouth.

5-Day Outlook as of 3/11/26

We seem to be flip-flopping between winter and spring weather, which can significantly impact your fishing day. At the start of this week, we'll see snow and high winds, while it will get warm toward the end of the week.

Techniques & Tips as of 3/11/26

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.
