Snake River
Still a heavy emphasis on midges both above and below the surface on the Snake at the moment. Most top-water action is occurring from around 1pm until an hour before dusk. Double nymph rigs are the way to go from 9am until noon. After that, dry-droppers will get the job done for the rest of the day. Nothing set in concrete here, but this is the way it has been going over the past two weeks or so. Target ledge rock pools, eddies, and seams separating backwater channels from main currents.
Dry flies – Furimsky BDEs, Parachute Midges, Ritt’s ARF Midge, CDC Midge Emergers, and Chez’s Parachute Midge Emerger.
Nymphs – Duracells, Zebra Midge Emergers, Ice Cream Cone Midges, Booty’s Day-2 Midge Pupa, Pure Midges, and Perdigons.
South Fork
As on the Snake, midges are the prime focus and the time frame remains the same – surface action from 1pm until around 4pm and nymphs working after 10am with shallower in the water column being the way to go as the day progresses. Riffle pools, seams, and banks with slow currents and moderate depths.
Streamers have been working best on the lower reaches below Wolf Eddy and down to Menan. Fish them on floating lines or INT sink tips and go with slow retrieves. Target seams, eddy current margins, and slow pools in backwater side channels (especially on the lower reaches).
Dry flies – Griffith Gnats, Renegades, Mating Midges, Parachute Midges, Ritt’s ARF Midge, CDC Midge Emergers.
Nymphs – Rainbow Warriors, Copper Johns in red or black, Zebra Midge Emergers, Ice Cream Cone Midges, Rojo Midges, Bling Midges, Perdigons, and RS-2s.
Streamers – Slump Busters, Mini Game Changers, Rickard’s Seal Bugger, and Krystal Buggers.
