Yellowstone Fly fishing report – Firehole River
The Yellowstone fly fishing season opened yesterday! Opening day typically means dry flies on the Firehole River, but this year nymphs and wet flies were the best. We began our day in the Firehole Canyon with flows around 500 cfs. Flows had dropped from 1000 cfs a few days earlier with cooler weather and some light rain. Word was that the Stonefly nymphs were already on the banks, so we had to see for ourselves.
The Stonefly nymphs were there and the trout were looking for them! We fished #4-10 Rubberlegs with varying droppers – #12 Prince nymph, #16 Pheasant Tails and Red Copper Johns. We found several willing trout in the slower moving runs close to the Gibbon confluence. A few Brown trout even ate big foam dry flies in the pocket water closer to the falls.
After lunch we moved upstream to look for some more dry fly fishing. We were deterred by the crowds at Fountain Flat. We kept going to the Mallard Creek area and found fewer people. The long runs in this area looked promising for finding trout rising to dry flies, but we only found a few fish looking up. They were willing trout and smashed a #16 Yellow Film Critic on first pass.
The water was still a bit high, and as a result nymphs and wet flies were more consistent. Red Copper Johns and Pheasant Tails were really all you needed. Swinging small yellow soft hackles through the riffles was also very productive.
All in all, it was a solid day on the Firehole. The flow drop definitely helped the fly fishing. Weather for the next week is forecast to remain in the 50’s, so it looks like flows will remain consistent in the 500-600 cfs range. We will be run guided Yellowstone fishing trips here for at least the next three weeks.
Yellowstone fly fishing – Lewis Lake
I drove through the Lewis River drainage on my way up to the Firehole and stopped to see how Lewis Lake looked. It looked great, if you were going to ski across it! The parking lot was plowed, but the boat ramp and lake itself were still under a couple feet of snow and ice.
What a difference a year makes! On Opening Day in 2016,we motored all the way to the Lewis Channel and caught numerous trout. Lewis Lake should thaw out by June 10th, but it all depends on the weather!
