Snake River
Pretty much a carbon copy of what we have had on the Snake over the past month with strong emergences of PMDs, Claassenia stoneflies, hecubas, and caddis on all reaches, and very good action on dry flies, nymphs, and streamers.  Dry-dropper rigs are a good route to go in a variety of holding water types.  Smaller mayfly and caddis imitations, especially those used as part of a tandem dry fly rig, are also working in many holding water types, but are ideal in skinny water and side channels, both of which have come into their own over the past two weeks.  Streamers are working well along banks and structure, as well as in the tailout of riffles and seams.
Effective dry flies – Grape Magics, Rubber Legged Double Humpies, Circus Peanuts, Will’s Winged Chernobyls, Parachute Hares Ears, Parachute Adams, Parachute Extended Body PMDs, and Cahills, Ausable Wulffs, Booty’s PMD and Mahogany Dun Emergers, Quigley Cripples, Film Critics, Booty’s Brown Drake Emerger, Tilt-Wing Caddis, and X-Caddis.
Effective nymphs – Lightening Bugs, Rainbow Warriors, Copper Johns in red, olive or black, Psycho Princes, Bruised Mays, Booty’s Deep Stinker Nymph, and Flash Back Pheasant Tails.
Effective streamers – Silvey Sculpins, Bow River Buggers, Chickletts, Booty’s Quad Bunny Leeches, Baby Bunnies, Lite Brite Zonkers, J.J. Specials, Marabou Muddlers, and Murphy’s Bling Minnows.

South Fork
Flows on the South Fork have stabilized and currently stand at just under 7600cfs at Palisades Dam.  Fishing has improved greatly and, as on the Snake, all reaches are fishing well with a variety of patterns and tactics.  The most active emergences include mutant stoneflies, caddis, pale morning duns, and some mahogany duns.  Dry attractors fished with a dropper remains a good way to go when targeting banks, eddies, seams, and riffles pools.  This is especially the case in the morning hours.  A LOT of fun can be had with smaller mayfly and caddis imitations in the same water in the afternoon.  Double nymph rigs have also been productive.  All of these options can be fished throughout the day, but sticking with the” dry-dropper in the morning, caddis/mayfly dun in the afternoon” plan is the best route to go.
Effective dry flies – SRA Chernobyls, Snake River Water Walkers, J-Slams, Circus Peanuts, Kasey’s Creature, Stimulators, Parachute Extended Body PMDs, Parachute Adams, Comparaduns, Snowshoe Duns, Booty’s PMD and Mahogany Emerger, Pheasant Tail Emergers, Quigley Cripples, Elk Hair Caddis, X-Caddis, and Tilt-Wing Caddis.

Flat Creek
Still some very good fishing on Flat Creek, and it actually has fished better than usual for this time of year over the past two weeks.  Part of this is due to cooler temperatures, part is due to a very healthy population of cutthroats on the stream, but another big reason is the unusually low number of anglers hitting the Creek this September.  There are still some grasshoppers about and these are being joined by PMDs, caddis and tricos.  Wetter days are producing strong hatches of PMDs, caddis, and tricos as well as some mahogany duns.  While mornings (8am to 11am) and evenings (4pm until dusk) are still the best hours to fish, we are now hitting that time of year when Flat Creek will fish well throughout the entire day.
Effective dry flies – X-Caddis, Tilt-Wing Caddis, U-Cons, Air-Flo Tricos, Parachute Tricos, Parachute Extended Body PMDs and Mahogany Duns, Snowshoe Duns, Booty’s PMD and Mahogany Emergers, Quigley Cripples, Pheasant Tail Emergers, and Film Critics.

Salt River
This is a beautiful time to be on the Salt River with its stunning autumn foliage and hungry cutthroats and brown trout.  The entire reach of the river is fishing well.  The best reaches are those running from Freedom down to Bistro.  Riffles and seams are fishing best with a variety of nymphs and dry flies, as are eddies and flats.  On overcast days and days with precipitation, eddies and flats can fish better than all other types of holding water.  The strongest hatches over the past week include tricos, PMDs, mahogany duns, and caddis.
