Glacier Anglers's Tip of the Week

Have some fun matching the hatch this week instead of the 'ol reliable chubby. We are having success with spruce moths, all sizes of mayflies in soft water, and we are starting to fish more terrestrials.

5-Day Outlook as of 8/4/26

River levels have dropped significantly in the last week, so the upper stretches are skinny. Water levels have stayed cool with the smoke blocking the sun, but we are expecting hot weather this week, so bring a water thermometer.

Techniques & Tips as of 8/4/26

Look for aerated pockets and deep runs for the stoneflies (smaller profiles #14), and target sippers in soft eddies with tiny (#16-18) mayflies or caddis.
