5-Day Outlook as of 4/3/25

There is a winter weather advisory for the next two days, but sunny weather is expected over the weekend and next week, with air temperatures near 60 degrees and lows above freezing. This may get the fish moving, as water temps warm a bit.

Techniques & Tips as of 4/3/25

Drop a perdigon nymph, San Juan worm or a girdle bug to the bottom and don't move it much. Stay away from shallow riffles or fast water. Look for slow, deep holes in known overwinter areas, like mouths of creeks (be sure to be fishing in the river, and not in the creek as they are closed during the winter) and large eddies.

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.
