When I walked to the creeks edge at ~12pm on the 6th I wasn’t expecting to see aggressively rising trout but I did. I thought at first random Caddis so I tied on a #18 Grey Caddis imitation and took a couple with long slow drifts but I could tell something was wrong. The rising I saw was aggressive whereas the strikes on my fly seemed hesitant so I stopped and waited until I saw what I almost couldn’t believe I saw and in June no less. I moved to knee deep water well behind a tasty run where I watch the first of many float past. E. Invaria, the Lt. Hendrickson. What I noticed immediately upon inspection was the vibrant yellow in the dark dun wings, the females were especially brightly colored with lighter colored bodies where the males had a darker body. I put on a slightly large #14 imitation and watched it get crushed almost before it hit the surface of the creek, no hesitation whatsoever. For the next three hours I played with bugs, took photos and nailed almost every trout that I wanted to. I sat, watched, waited and when I picked my fish it was all over. The quantity of adults was just enough to light the fish up making them want my fly almost everytime, I couldn’t have been more into hanging out on that run. It’s been an odd spring with few dry fly opportunities, interesting that the day I choose to fish streamer water for a bit I end up casting a dry fly under cloudy skies for just over three hours. I watched as sparrows from a nearby pole barn swooped in to grab the flies just before the trout could nail them. For a minute I actually thought my dry fly would fool one of the birds, I had to pull it out of the way during on pass to avoid what I thought was going to be disaster. I fished my dry fly until I had my fill then proceeded to my original plan, chuck a streamer to dark nasty places. An hour of streamer tossing saw three nicer trout come to hand but it was no comparison to watching the launch of an aggressive trout hit a dry fly. I had my fill and was content to head home. Side note: The water temp was ~57 degrees on arrival. Lt. Hendricksons typically hatch between 55-60 degrees. We don’t have large quantities of these flies on most creeks so when you do come across them take a moment to enjoy it and remember where your at so you can try to catch it again.
