Glacier Anglers's Tip of the Week

The scenic walk or float is worth it, even if the fish are a bit harder to find. Adfluvial cutthroat are moving toward the big lake, and there aren't many left in the upper stretches. Look lower on the system.

5-Day Outlook as of 10/16/26

The weather is looking stellar, but it's a bit cold in the mornings for fish (and humans) to move around much, so consider waiting until midmorning or afternoon when water temperatures rise above 50-degrees.

Techniques & Tips as of 10/16/26

Bounce a few caddis in the soft seams. Let those little ants fall near logs and overhanging banks where they natuarlly would fall into the water. Look outside the classic "fishy" banks, and try fishing large, foam terrestrials smack dab down the middle of the river and in sportier runs. Bigger fish are still rising in bigger water to bigger bugs.
