Hebgen: Reports for the lake have varied, but it seems to be getting better. Keep an eye out for fish rising to Callibaetis and tricos on calm mornings. Searching around with an ant pattern can be effective if fish aren’t coming up. Nymphing a tandem rig with a callibaetis and chironomids can be worth your time as well.

A few chilly and rainy days, combined with cool overnight temps the past week have helped keep the water temperature down and the fish happy. Nymphing remains your best bet if you are after numbers. We have been fishing mostly smaller rigs (#16-18) lately but have had a few fish eat hopper patterns as well. The terrestrial bite has been inconsistent, but ant and beetle patterns have been productive. Make sure the fish eats your hopper/ant/beetle and turns their head before you set the hook!
Flies: #16-18 Pheasant Tail, #16-18 Black Lightning Bug, #18 Split Case BWO, #16-18 Guide Dip, #14-16 Lake Prince, #14 20 Incher, #16 Olive Hot Spot, #16 Firestarter #12-14 Pink Thunder Thighs, #10-14 Tan Morrish Hopper, #16 Hi-Viz Cinnamon Ant, #16 Parachute Ant, #16 Sparkle Dun, #16 Rusty Spinner #6 Mini Dungeon, #6 Sparkle Minnow Royal Oil
Gallatin: The Gallatin continues to fish well with terrestrials and small attractor dry flies. The colder nights have kept the water temps extra cold here, so it never hurts to get a later start, or just fish the afternoon and evening hours. Try dropping a nymph a couple feet underneath a smaller hopper pattern if the fish aren’t looking up.
Water Temps on the Firehole, Gibbon, and Madison have started to be too hot for ethical fishing, so we recommend finding somewhere else to fish and come back during the fall once water temps cool back down. Instead look towards the Yellowstone River where the fishing has been good.
Flies: #14 Yellow Morrish Hopper, #12-14 Grand Hopper, #16 CDC Flying Ant, #16 Nyman’s Flying Ant, #12 Longhorn Beetle, #16-18 Royal Wulff, #16-18 Purple Parachute
