Fall is knocking. Dust off those streamer boxes!
Hebgen: This is the prime time to fish Hebgen. Anglers on watercraft and wading have been catching cruising gulpers on both of the arms of the lake. When you aren’t seeing fish rise it may be worth stripping leeches, larger streamers, or large damselfly nymphs in the upper reaches of the arms, as migratory fish should start staging any time in the coming weeks.
Flies: #8 Black or Olive Simi Seal Leech, #6 Balanced Squirrel Leech Black, #6 Olive or Black Hot Bead Leech, #8 Thin Mint, #12 Balanced Damsel, #20 Trico Spinner, #16 Callibaetis Sparkle Dun, #16 Found Link Callibaetis, #16 Purple Missing Link, #16 Long Tailed Callibaetis Spinner
Inflow to Hebgen Lake: 921 cfs
Hebgen Lake Outflow: 985 cfs
Kirby Flows: 1090 cfs
** Flows as of 3 pm September 3rd, 2023 **
Upper Madison: Not much has changed on the Madison since last week, It’s still nymphing very well. Smaller mayfly and caddis nymphs, as well as dip style midges are what we’re throwing lately. Hoppers are fishing a little better but still not as consistently as we’d like. Throwing a hopper dropper is the best of both worlds and a good way to search/cover water. Other terrestrials and streamers are also moving fish on slower days.
Flies: #16-18 Redneck, #16-18 Shop Vac, #18 Black Crystal Dip, #18 Olive Micro Mayfly, #18 Hogan’s S&M Black, #14 Olive Hot Spot, #18 BWO Comparadun, #16 BWO CDC Comparadun, #16 Pink or Tan Chili-Dog, #12 Carnage Hopper, #10/12 Tan Thunder Thighs, #6 Black Hot Bead Leech, #4 Olive/White Barely Legal
This is the prime time to be in the NE corner of YNP!!
Madison near West Yellowstone: 377 cfs
Yellowstone below Yellowstone Lake : 1400 cfs
Gibbon: 111 cfs
Gallatin near Big Sky: 426 cfs
** Flows as of 3 pm September 3rd 2023 **
Gallatin: The Gallatin is low, clear, and cold enough that you don’t need to be there before 10am. Fish should be rising pretty readily to terrestrials like beetles, ants, and hoppers. Smaller attractor dries like Royal Wulffs and Stimulators should also entice a rise. Fish in the upper Gallatin tend to reside in deeper runs and pools this time of year so avoid shallow runs and riffles all together.
Flies: #16-18 Shop Vac, #16-18 Black Krystal Dip, #16 Pink Chili Dog, #14 Royal Chubby Chernobyl, #18 Parachute Adams, #16 Orange Spruce Moth, #16 Rocky Mtn Mint PMD, #14 Royal Stimulator, #16 Arrick’s Ant, #14 Royal Wulff, #16 Bionic Ant Brown
Madison/Firehole/Gibbon: Temps on the western side of the park are finally falling enough to make the Madison, Firehole, and Gibbon viable destinations again. We would still recommend caution on the Firehole as it will be the last river to stay consistently cool. The Madison and Gibbon are fishing well with nymphs, hoppers, and streamers. Lake fish should be arriving any week now.
Flies: #8-10 Partridge and Orange, #8-10 Partridge and Pheasant Tail, #14 Prince Nymph, #16-18 Frenchie, #14 Diving Caddis, #6 Olive Slump-Buster, #6 Olive Montana Mouthwash, #8 Black or Olive Hot Bead Leech
Yellowstone/NE Corner: The Yellowstone is slowing down drastically as the season continues. The Lamar and its tributaries are all fishing well with fish looking up, however, with recent weather the Lamar could be higher than average in the lower reaches. Look for fish rising on Tricos and small BWO’s. Pink, purple, and red chubbies, as well as other terrestrials like will also fish well. Streamers should fish well if dries are slow.
Flies: #18-20 Parachute BWO, #18 Guide Winna Spinna, #10 Yellow Thunder Thighs, #16 Rocky Mtn Mint Adam’s, #16 Butch Sally, #14 pink/purple/red Chubby Chernobyl, #6 Black Hot Bead Leech, #6 Olive Slump-Buster, #6 Olive/Black Crystal Bugger
