Glacier Anglers's Tip of the Week

Rain and warmer air temperatures have fish rising to bwos and midges on the lower parts of the main stem. Look for slower eddies and soft shoulder runs in the main stem toward Flathead Lake as these cutthroat are adfluvial and move to Flathead Lake in the winter. There are some resident cutthroat who hang out near the tributaries in the winter, but not many. Enjoy North Fork river walks and sightseeing, but leave the casting for the main stem near the lake.
