South Fork of the Snake River Fishing Report – October 1, 2026

Fly fishing guide Chase Hines with a nice fish.

October is here!  Those that spend a lot of time on the South Fork know how special this time of year is on the river.  We hope you get out there and enjoy it, the snow will be flying soon enough.

River Conditions

Palisades Reservoir sits at 11% capacity, and flows out of Palisades are running at 4,200 cfs. The water on the upper river is still a little off color, and we’re starting to see some moss floating freely in the river as well. Neither one is slowing the fish down much. The fishing remains good, especially for anglers willing to go small and technical.

The Word From Our Guides

Much like last week, there are still a few opportunities for terrestrials and hopper-dropper rigs, but they’re limited. On these bright, sunny days you’ll be best off with a double nymph rig under an indicator. The fish are keyed in on small, technical bugs this time of year, and that’s where most of the action is coming from.

The foam lines are where you want to be. That’s where the food collects, and that’s where the fish are sitting and feeding.

Tactics: Small Bugs, Double Nymph Rigs

This time of year we like to fish really small. An olive tungsten thread midge in size 18 or 20, trailed by a size 18 or 20 BWO soft hackle or emerger, is a go-to rig right now. A couple of patterns from the shop that fit the bill:

Looking Ahead: Flip-Flops and Sunblock

The forecast looks warm and sunny, which means flip-flops and sunblock for a couple more weeks. If you can get out on the river on the next cloudy day, do it. That will be your best shot at good BWO hatches and fish rising. Until then, get those flip-flops out, grab the sunblock and a cooler, and enjoy these beautiful fall days on the river.
