Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This one seems to tentatively key to Holocentropus, although I can't make out the anal spines in Couplet 7 of the Key to Genera of Polycentropodidae Larvae nor the dark bands in Couplet 4 of the Key to Genera of Polycentropodidae Larvae, making me wonder if I went wrong somewhere in keying it out. I don't see where that could have happened, though. It might also be that it's a very immature larva and doesn't possess all the identifying characteristics in the key yet. If Holocentropus is correct, then Holocentropus flavus and Holocentropus interruptus are the two likely possibilities based on range, but I was not able to find a description of their larvae.
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.

I was in Portland this week for the annual meeting of the American Fisheries Society, and I had time early Monday morning before the sessions started to meet up with a fishing buddy from college (thanks, Willy!) and try for some trout. That area is in the midst of a serious drought, so fish were hard to come by, but we each managed to draw a bit of interest in our flies, and I finally landed one fish.

It was only about 8-9" long, but it was my first cutthroat ever! I've been running a website called "Troutnut" for far too long to have never caught one of North America's major species. Problem solved now. Next up: golden trout? One can hope!

Nice! That is a good looking piece of water even in its low state. CJ

Beautiful photos. And congrats on the cutt. I have yet to catch one. And for me there's grayling. And goldens. And . . .. Pisces multos; vita brevis.

Congratulations, Jason!

I've caught a grand total of 2 Cutts, both out of a small trib of the SB of the McKenzie in Oregon. Size wise, they were just about identical twins at 13".

That's combined length, of course...:)

So, you're still up on me....

Congrats, Jason! Another species to add to your "life list". They are pretty things, aren't they? I caught a few sea-run cutthroat while living on the Oregon coast back in '92-'93, and one more (though not on a fly rod) while on Vancouver Island back in 2001. That is beautiful looking water there too! Oregon is a beautiful state, and I would love to live and explore there again some day...

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

Nice. I spent some time in the Blue Mountains (catching spotted owls with the USFWS) and got to see many cutts in the small steep timber-strewn streams in the gulch bottoms, as well as blacktail deer. Didn't fish but I still remember them. The memory still quickens my heart a bit.

You actually were in the Lower 48! Incredible! I thought you had totally gone native up there and we would never see you again. :)

That is a pretty fish!

Is that a genetically pure cutthroat or a rainbow/cut hybrid? I never saw a cut with such rainbow trout looking flanks. But then again there must be close to ten sub species of cutthroat found all over from Wyoming, Colorado, and Montana all the way to the Pacific Ocean.

Edit - I just Googled "Cutthroat trout" and found out that there are fourteen subspecies of cutthroat identified.

This is a coastal cutthroat trout, which looks like that. I was surprised and unsure at first, too.
