Glacier Anglers's Tip of the Week

Most cutthroat trout on the North Fork are migratory, moving to Flathead Lake for the winter. You'll find them on the lower stretches. We have not been seeing the large October caddis that we had in September, but the sunny days will have fish rising to tiny dries.

Beautiful fall weather for the next week will have smaller dries like midges hatching and be effective in slower seams.

Techniques & Tips as of 10/5/25

Looks for slowly-moving water for small dry flies, or deep eddies and tailouts for long perdigon droppers below terrestrials.
