Snake River Now is the time to be fly fishing on the Snake River in Jackson Hole! Cutthroat are looking up and eating off the surface in a variety of water types – riffles, seams, and along bank structure. Our fall Drake hatch, Timpanoga Hecuba, is in full swing, along with Mahoganies, Flying Ants, Stoneflies, and Blue Winged Olive’s. Check out the Drake photo below taken by fly fishing guide Tim Smith during a lunch break last week. Cold nights have meant that early starts are not important. It seems the earliest fish are eating off the surface is 10am and on some days it’s more like noon. The good news is that the action lasts until 6pm or later. The streamer bite has picked up as well and are best early and late in the day. The Jackson Hole One Fly was a blast this past weekend! Fish the Fly owner Jason Balogh and guide Tim Smith both guided on the Snake. Hecuba Drake patterns produced the best along with some Stonefly patterns. All the monies generated by this event go to funding stream conservation projects in the region.
Fall weather has arrived in Jackson Hole since our last fly fishing report. We have had a few frosts already and this has really woken up our mayflies on both the Snake River and Fish Creek. Hecuba Drakes, Mahogany Duns, and Baetis are all hatching currently and hatch times vary depending on the weather. On cool sunny days, bugs arrive around 11am and on cloudy days it’s more of an afternoon affair. It’s been worth it to fish in the rain as this is when every fish in the river is on the surface feeding. The Hecubas pour off the water, especially side channels, on these gray days. I’m surprised that any of these bugs survive after watching them hatch one afternoon and seeing how voraciously the cutthroat feed on them! Flying ants started swarming last week in the afternoons and this is a great option for picky fish that refuse other flies presented to them….
Snake River The Snake River through the Jackson Hole valley has remained consistent dry fly fishing since our last report. Our fall stonefly, Claasenia Sabulosa, has begun to emerge in all sections and has kept the cutthroat looking up for big bugs, especially early and late in the day. Look for these to continue into September and twitch those flies! PMD’s and Little Yellow Stones are still popping around 11am and fish key in on them in those riffles where they are present in good numbers. Grasshoppers, Beetles, and Flying Ants are becoming more important on our warmer afternoons. Rhyacophilia Caddis are out and about and give you another option for dry flies. We will start looking for Timponoga Hecuba mayflies to emerge in the last part of this month on our cloudy days… Best Flies: #8-10 Olive, Tan, Purple Water Walkers, #10-12 Red Fat Alberts, #16 Q’s Sparkle Stacker, #12-14 Lime PMX, #12 Yellow Stimmies, #12 Tan, Green Grand HopperBackcountry Creeks Some of our larger, and therefore colder, backcountry creeks are still fishing well. We are still seeing Grey Drakes on these creeks and the cutthroat dig them! If you look closely, you will see a few Claasenia Sabulosa shucks on the more oxygenated riffles, so larger Stonefly patterns are in play and have been productive early in the mornings. Grasshoppers are coming into play more each day….. The smaller creeks are a bit too warm in their lower reaches to be very productive, but if you like to hike they can be very rewarding higher up where the water temps are cooler…
Wyoming Senator Mike Enzi held his annual fund raiser yesterday and Fish the Fly was proud to host the fishing portion of the event. We had 14 boats spread out through the entire length of the Snake river from Grand Teton National Park all the way down to the whitewater section south of town. This is our 4th year hosting this event and we look forward to next year! Everyone had great time and fishing reports came back very solid for all stretches. Our fall Claasenia Stonefly has begun its hatch on the whole river and this has the cutthroat chasing big bugs on the surface. Localized PMD and Yellow Sally hatches are still important and fish will focus on them in certain areas where they are hatching. A few pickier fish are eating Caddis and Beetles as well. Look for a more detailed report soon….
It’s terrestrial time here in Yellowstone country! The Yellowstone River tops the list for large cutthroat eating small hopper patterns, flying ants, and beetles. PMD’s and caddis are still on the menu as well. Cover a lot of water and look for noses tight to the banks or fish that are cruising. Make a great cast and you will be rewarded with cutthroat up to 23″! Tributaries to the Yellowstone, such as Blacktail Deer and Hell Roaring, fish well with mayfly attractors and hoppers. Now is a great time to pick any creek in the Park and take a walk with your fly rod…. Closer to home, Lewis Lake has been fly fishing well during PMD hatch times 10am-12pm or so. Cruise the shorelines and look for rises even if you don’t have a boat. Caddis action in the evenings has been solid and offers up great fishing for brown trout to 20″. Best Flies: #10-14 Grand Hoppers , #14-16 Flying Ants, #14-16 Black Beetles, #16 Royal Wulffs, #16 PMD Cripples
