Baetis

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 is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.
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.

Here's a photo of a brown caught on this trip. The weather was fickle, but when conditions allowed, fish were up and eating. This fish took a sulphur.

That's a big one Louis! Especially on a little dry fly. I know there's fish like that around here, but it might be the middle of the night in summer with big streamers...I did hook and lose one like that years ago, took off on me and wrapped me under a log, that took a Hendrickson dry about this time of year too.

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

Awesome fish!! Now that looks like one of those Big D fish I remember seeing but rarely seeing anyone land at the Junction.

Hey Matt, thanks, but that's just one to your hundreds of fish like that. When I grow up, I want to spend more time on that river. You know the one.

Louis,

Yes, I know the one. I had a great day on Wednesday with our friend. He landed two good fish, one 17" and the other 18" and he had a bunch of other opportunities.

I've been fortunate to have fished that water for over four decades and have had ample time to learn pretty much where the best lies are, and big fish, like to hang out. Couple that with having good patterns and being able to fish during the week enables me a huge advantage over guys like yourself who are often limited to fishing long weekends.

Hopefully I'll still be around when you retire and we can go out together and get those big browns!

I'm sure that helps! I never seem to be able to live ANYWHERE long enough to learn that. Although, now I am not too far away (one hour drive) from the Rifle River which I fished for four seasons ('98-'01) and am getting to know all over again. With some luck, I'll be able to figure out where the big bruisers live and what it takes to catch them like Matt. And I've got a ways to go before I retire!

Louis,

So that's what you look like brother! It's good to finally put a face with a name from this site...It took such a nice trout to get you to take a bow! Lovely fish there mister...:) The bigger the fish on the smaller the fly the broader the smile...

I'm heading north at the end of next week for ten days...I've been wrapping flies to cover E invaria and E dorothea...among others of the familiar suspects from this time of year...I have been playing with the "new" stuff all winter, but have been filling the holes in the boxes of the tried and trues over the last couple weeks...When you finish a fly that you have caught so many fish on in the past a man can get excited in a way only another angler would understand. :)

Thanks for the encouragement!

Spence

Beautiful fish! Quite the use of perspective, too -- makes a really nice fish (I'm guessing 23"?) look like a world record until I realize it also makes your hand look bigger than your head. :)

Here's a photo of a brown caught on this trip.

Like the Batman or Phantom of the Opera, we know who did the deed (by indirect confession), but we can't be sure of who's actually in the photo! Hell of a fish you caught there Louis, but who's actually holding it for the photo? A boat mate perhaps? Ah, the subtlety of the English language. Me thinks there's a possibility that the actual physical appearance of Martinlf is still safely ensconced in the imaginations of all Troutnuts... :)

A pox upon you, Jason! We never mention such things unless it's a response to the bold post of a newbie in need of a proper sense of the pecking order! :) LOL

Jason & Kurt...I should show you sometime the photo of that fish in my profile picture I took of my guide friend holding it...Can you spell Moby Dick...:) He wanted to give it a "guides-measure" but I put an end to it at an honest 20.5"...Give or take ;).

We are just teasing you Louis...Kurt Photo-Shopped in his steelie in his profile pic...:) Don't tell anyone...

Now that you mentioned it Spence, the fish in your profile picture does look kind of puny compared to Kurts, Orn, Wbranch. That is why I use a large variant in mine.

Yes, the perspective in the photo has been manipulated a bit, but it wasn't my doing. My photographer gave me very explicit directions which I innocently followed, being, as some have noted, a bit camera shy. As for the actual size of the fish . . . I'll have to leave that up to your imaginations. :)

And Louis that is as it should be...:)

Back it 1995 I shared a float with a professor from Sacramento on the Madison and I caught a 23.5" Brown...He being a history professor measured the fish and proclaimed, "This fish will from here-on-in be known to be 23.5" and so it will be written from here in perpetuity..." After that it was impossible to smudge that extra half inch so I could call it a two-footer...Damn him! :)

Spence, that's the fly-fishing version of "keepin' it real"...

I have been seeing a lot of little brown caddis, #14-16, on my local streams lately, so you might want to make sure you have a few in your box for your upcoming trip. And yes, fish have been hitting imitations quite well. And the old secret weapon #10 Royal Wulff has come in handy a few times as well...
