Henry's Fork is the place to be, but the South Fork, Green, & below JLD are respectable options.

Snake River

The Snake is in runoff and the most consistent fishing now on the tailwater reach just below Jackson Lake Dam where releases are currently in the 850cfs range. Only midges on the surface for the most part but there can be a smattering of blue-winged olives and even some skwalas from time to time, giving fly fishers the chance at hook ups on mid-sized attractor patterns. Nonetheless, the most consistent action is coming on nymphs, particularly on the upper reach from the spillway down to Wormhole and on the far lower reach just above Pacific Creek. Leader lengths in the six to eight foot range is sufficient for most waters you target but be prepared to shorten up by a foot to a foot and a half in shallower and slower water. Concentrate on seams, riffles, and eddy current margins.

Streamers are working well in the spillway as well as in eddy pools, seams, and along banks and structure (the latter particularly in the Dead Sea reach below the Oxbow). Go with moderately sized baitfish imitations fished on floating or intermediate sinking lines or sinking tips in the 3ips to 6 ips range or short lengths of T-8 or T-11. Slow retrieves are working best, but be prepared to vary it up and throw hesitations into your line strips every now and then.

South Fork

Flows from Palisades Reservoir continue to ramp up and currently stand at approximately 11,500cfs. Visibility is noticeably better than it typically is this time of year especially on the upper reach above Hwy 26 bridge, although water temps are fairly cool. The most productive fishing has been with double/triple nymph rigs with leader in the nine to ten foot range from trailing fly to line/suspension device. Target sweeping riffles and riffle pools and seams first, troughs and banks second.

Streamers are fishing decent on the lower river from Cottonwood down to Lorenzo. Slow to moderate retrieves are working best with both larger and moderately sized baitfish imitations fished on floating or intermediate sinking lines. 3ips tips can also do the trick. Target banks, structure, troughs, the inside turn of riffles, side channels, and seams. Brighter patterns are outperforming larger ones.

Dry fly fishing has been very hit-or-miss but there is sporadic action of midges and BWOs on cooler and wetter days. This is especially the case on the upper reach from the Dam down to approximately Black Canyon. Target riffles, eddies, confluences with slow currents, and seam current margins

Dry flies – Parachute Adams, Booty’s BWO Emerger, Film Critics, Booty’s DL Cripple, Parachute Midges, and Chez’s Krystal Wing Midge Emerger.

Nymphs – Pat’s Rubber Leg, Kaufmann’s Stone Nymph, Duracells, Peach Fuzz Jigs, Copper Johns in red, Nymph Formerly Known as Prince, Flashback Pheasant Tails, San Juan Worms, and Squirmy Wormies.

Streamers – Galloup’s Sex Dungeon, Keller’s Nightmare, Booty’s Quad Bunny, Galloup’s Boogeyman, Goldies, Galloup’s Mini-Dungeon, Booty’s Tri-Bunny, Mojo Minnows, Kreelux, and McCune Sculpins.

Henry’s Fork

The Henry’s Fork continues to fish well with good to very good emergences of caddis as well as blue-winged olives on cooler and wetter days. There is also decent activity on the part of salmon fly nymphs on the entire reach of river. Fishing has been best on the lower reaches below Warm River. Nymph rigs are the name of the game in the morning with the best action occurring along banks and submerged structure as well as in riffles and riffle pools.

Surface action picks up around 11am and can intensify throughout the afternoon, especially on days with cloud cover. Think caddis more than anything else. Riffles, riffle pools and eddy current margins are fishing best. The most production is coming on tandem dry rigs consisting of emergent patterns or an emerger trailing an adult.

Streamer fishing has been hit-or-miss but on the days that it is on it can be quite good. Go with moderately sized patterns fished on intermediate sinking lines or sinking tips in the INT to 3ips range. Go with moderate retrieves and target banks, structure, and riffle pools.

Dry flies – Stimulators, Elk Hair Caddis, Mathew’s Sparkle Caddis, X-Caddis, Cole’s U-Con, Parachute Extended Body BWOs, Parachute Adams, Comparaduns, and Booty’s DL Cripple.

Nymphs – Pat’s Rubber Leg, 20-Inchers, Peach Fuzz Jigs, Duracells, Chamois Caddis, Mercer’s Bead Tail Caddis, Lawson’s Diving Caddis, Military Mayflies, Copper Johns in red or olive, and Lightening Bugs.

Green River

Flows are going up and the river is off color, especially below Daniel Bridge at the confluence with Horse Creek. Nonetheless, the Green has more than respectable action for those looking to get into larger fish. Don’t expect big numbers, but size is definitely in the cards. No real surface action as of yet but dry-dropper rigs and shallow double nymph rigs are working well when fished along undercut banks, submerged structure, side channel confluences, and eddies. Look to go between five and six feet on average for your leader length between trailing fly and line/suspension device, adjust when needed depending on depth, current, and rigging weight.

Streamers are working well on most parts of the Green with moderately sized bright baitfish imitations producing best above Daniel Bridge and larger, darker patterns working best below Daniel. Go with floating lines or sinking tips in the INT to 6ips range and slow retrieves. Speed it up to moderate line strips if follows and chases do not result in eats. Target banks and structure primarily. Seams and eddy current margins are worthwhile secondary targets, primarily in the morning hours.

Nymphs – Pat’s Rubber Leg, Kaufmann’s Stone Nymph, Deep Cleaner Stones, San Juan Worms, Squirmy Wormies, Duracells, Peach Fuzz, Batmen, Flashback Pheasant Tails, Rubber Legged Hares Ear Nymphs, and Copper Johns in red, olive, or black.
