Glacier Anglers's Tip of the Week

Last week had warm weather and moved some fish out of their overwinter areas and into the main Middle Fork channel, allowing for good wintertime fishing, but this week is set to be colder and fishing will not be as productive.

5-Day Outlook as of 2/16/26

Snow, rain and wind are expected, as well as more seasonable winter temperatures than we've been having, so fish will likely move back into their trips until the weather warms up a bit more.

Techniques & Tips as of 2/16/26

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.
