Fishing Report Updated August 8, 2022

This report is valid August 8 through August.

This is prime season for mountain small streams in all drainages. This includes Yellowstone River tributaries that are well known (Mill Creek) to unknown (not naming names here!), Hyalite Creek, the West Fork of the Boulder, and many others. Meadow streams like the East Gallatin and other low-elevation waters? Not so much.

The best flies are similar on all: #10–14 attractor dries, hoppers, and Chubby Chernobyls with #16 attractor nymph droppers. On Gallatin River tributaries, spruce moths can also be critical.

Except on the largest streams like Mill Creek, there’s never any reason to start before 11:00 or so, and the best fishing will be in the afternoons. The higher the elevation and the steeper/shadier the creek, the more this is the case.

Our next creek report will drop around September, when cold nights may put a damper on the mountain creeks but turn on the meadow streams again.
