Glacier Anglers's Tip of the Week

While river levels are stabilizing, it's still winter, so North Fork cutthroat, being adfluvial, have generally moved to their wintering area in Flathead Lake, and will be sparse in the river.

5-Day Outlook as of 1/12/26

Fish the main stem closer to the lake on consistently warm days when the fish sometimes move up the system to feed. Or, head to the Middle Fork where the fluvial fish can be found near their tributaries. Remember, tribs are off limits in winter.

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.
