The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

With water levels finally getting to a point that I feel safe wading I decided to head up and fish the afternoon and evening. I also planned to car camp the night and fish the early morning. I had just bought a new rod and reel and wanted to give it try. The early afternoon a few brookies, so after a quick bite to eat at the car I headed backdown to the river. I tied a mattress thrasher and caught a nice brown and a few more brookies. As darkness approached I switched to a brown drake pattern hoping for a hatch or spinner fall. As it got darker there were a few larger rise forms, one I tried to cast to was tight to sweeper with lots brush mixed in, I couldn't get a good cast to it. I then saw a small rise in front of me maybe 15 ft. away, I figured a small brookie but I thought a good way to end the night. Well, that small brookie turned into the biggest brown I have caught. I have not a fish fight like since my steelhead fishing days! I was amazed the 4x tippet held up, as I really had to put the screws to it when it tried to get into bankside logs. The rod in question a Gloomis nrx+ 4 wt. pushed to the max but did the job, Im not sure I will fish at night again with a 4 wt. I quickly took a couple of pics in the net, they don't do the fish justice, but I had a good case of the shakes, and it was pitch dark by now.

Big beautiful brownie there, Mike! Well done! Estimated size? 18-20"? More??

It's surprising how large a fish can be found mid-stream once it starts getting dark, I've often thought "that's a little guy" and been surprised by a fat boy sitting in less than a foot and a half of water. Ah yes, the challenge of summer evenings, along with keeping the mosquitos out of your face when changing flies in total darkness...but that's when the big browns come out on the prowl! And, big flies are any day now.

My biggest frustration is that deer flies have come out early this year! Repellent will be a constant need from now until September...

Again, congrats! Biggest ever? How big is the one in the top photo, that's a nice one too!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Jonathon, I don't have a tape on me although that is on my list. The fish took the mattress thrasher around 7:00 pm, it was around 15-17 incher. I really try to get fish off the fly and back in the water as quickly as possible. The second fish was taken on the brown drake pattern at about 9:55 pm, my thoughts are it was 20 plus, and such a thick body. I did not at the time but there was witness, he must of come in behind me and he watched the whole thing. I apologized for getting so far down stream but really I could not stop this fish. He was cool with it and since the fish made a couple of nice jumps he got a half way decent look considering the light. I need to work on getting a better camera, although I don't think I would jeapordize a fish for a pic, but still I love to take river pictures and wildlife all around me so it would money well spent. So maybe the hex up next? I don't know, I worry a little more as I have gotten older, especially after my little swim back in early march up there. It really does suck getting older, I never thought I would be getting out of the water in a lot places I would have waded when I was younger, but I do now.
Mike.

Mike, get a Measure Net! I have both the medium and large sizes now:

You'll always know, good for bragging rights!

Again, that's a big old brownie, not easily fooled. Well done! On both fish!
