Yellowstone National Park opened to fly fishing a week ago to little fanfare. Abnormally high daytime temperatures melted our dense snowpack and the Firehole River rose to record levels in a matter of a few days making fishing very tough. Both Yellowstone and Lewis Lakes still had ice on them leaving us dreaming of days to come… This week will be a different story! Flows are dropping on the Firehole to fishable levels and a few rain showers should spark the Mayfly emergences that this river is known for. Look for PMD’s and BWO’s to pop during inclement weather, especially in the afternoons. The ice is off Yellowstone Lake and there is some decent fishing to be had. It takes a few weeks for the water here to warm up and the trout to move into the shallows. Lewis Lake is just now icing off on the edges and should ice-free by the end of the week. It doesn’t seem to take quite as long for the fishing to get going on Lewis since Brown and Lake trout aren’t afraid of cold water. We’re pumped to be fishing in Yellowstone!!

The South Fork of the Snake River flowing through Swan Valley, ID has been fishing well recently. Flows out of Palisades Dam have remained steady for weeks at 10,400 cfs. The Rainbows on the Upper section have moved into full spawning mode, especially from the Dam down to Palisades Creek. The trout are taking #8-12 Rubberlegs, #12-16 Hares Ears, #14-18 Red Copper Johns, #14-18 Lightening Bugs, and San Juan Worms. Typically we do not condone fishing redds. In this case, Idaho Fish and Game encourages a catch and kill policy on Rainbows, which is counter-intuitive to what most of us are used to. This practice helps the native Cutthroat as they don’t cross breed or have to compete with the faster growing Rainbows. There are numerous Rainbow fisheries across the land, but very few Native Cutthroat fisheries especially on large fertile rivers. Releases will be bumped up starting next Tuesday to mimic natural runoff conditions. By mid-June, we expect flows to level out around 15,000 cfs and for the Stonefly hatch to begin in earnest!
The Green River just outside out of Pinedale, WY has been fishing well recently. Flows had bumped up over 1000 cfs with some warm weather at the beginning of the month, but have dropped over the past few days and the Green is clearing. Water clarity is three feet and the trout are feeding on nymphs and streamers. Double nymph rigs with Rubberlegs trailing Princes or San Juan worms have been effective. Streamers are best on a sink-tip line to help get the fly in front of the trout. Olive Wooly Buggers, JJ’s Specials, and Natural Dungeons have been the ticket to finding some larger trout.
