Hebgen & Quake Lakes: The lakes are fishing very well right now. Callibaetis are hatching sufficiently enough to fish them on the calm mornings, but if there's any chop, switch to subsurface techniques. Leeches and chironomid imitations have been the ticket under the waves.

Upper Madison:
The 50 Mile Riffle is rapidly becoming its mid season usual, with some days being a bit more tricky than others. The bugs have definitely declined but we're still seeing sparse caddis, and PMD's, along with BWO's and Epeorus down there. The fish lower on the river are starting to turn on to hopper and similar attractor patterns as well. Nymphing has been the most productive but the fish are pretty dialed in on smaller natural patterns (18's and smaller). Streamers can still move fish, particularly on the stormy and overcast days.
Flies We're Fishing:
#18 Olive Hot Spot Perdigon, #16 Sunburst Perdigon, #18 S&M Dark Baetis, #18 Purple JJ Baetis, #16/#18 Black OR Red Krystal Dip, #16 Pilva's Perdigon - Olive, #16 Purple Parachute, #14-#16 Brown X-Caddis, #14 Missing Link Caddis, #16 OR #14 Royal Chubby Chernobyl, #16 Peacock Chubby Chernobyl, #4 Olive Supernatural Peanut, #6 Olive MT Mouthwash, #6 Olive/White Barely Legal, #8 Hot Bead Leech - Olive, Black, Brown

Firehole: The Firehole, Madison, and Gibbon - (below Norris Campground) have all been indefinitely closed to all fishing.
Gallatin: The Gallatin is fishing pretty well throughout the whole river. Lots of bugs in the park section right now, caddis, yellow sallies, BWO's and PMD's. Attractors and small hoppers should rise some fish too!
NE Corner: The Yellowstone River is running at about 2000 CFS which is near perfect for hunting noses with dry flies. We've been getting fish on yellow sallies, PMD's, and smaller attractors like Wulff cripples and ants. The Lamar, Soda, and Slough Creek are all fishing great with similar action on top. There has been some bear activity/carcasses above the Lamar canyon so bring bear spray if you're up there and keep your head on a swivel!
