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

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.

I caught a yellow trout in a western Oklahoma pond that is stocked yearly with rainbow trout from Arkansas. Are these yellow trout common? We have fished this pond regularly through the trout season for three years and this is the first of this kind we have seen. Oh, how do I post a picture?

Go to the photography section of the forum and start a new topic there. It'll give you the option to "save and add pictures" where there's an easy form to attach a picture.

Sounds like an interesting fish! I'll look forward to the picture.

We have a lake near me, Rigby Lake, that depends on river water to fill it in the high water Spring, and dries up when the river drops in the Fall. The state stocks it with "Banana Trout" they call them that are yellowish rainbows. I do not know the hybridization.

In PA they refer to them as Palomino or golden rainbow trout. If I remember correctly they are essentially a cross between a brown and a rainbow and are sterile. So they are only common in place they are stocked.

JohnW and Sayfu
A palomino trout or "golden rainbow" trout is actually a distinct color variation of the common "rainbow" trout. They are both Oncorhynchus mykiss. The coloration can be selectively bred by mating like colored adults, much the way fine quality feather hair extensions (I mean dry fly hackle) is bred.
Oh, and they can reproduce in the wild.
All men who fish may in turn be divided into two parts: those who fish for trout and those who don't. Trout fishermen are a race apart: they are a dedicated crew- indolent, improvident, and quietly mad.

Yeah, I agree that it is most likely a golden rainbow. You said the hatchery where it came from is in Arkansas, and the state of Arkansas has recently taken to buying these unusual trout from private hatcheries to replace regular rainbows from the federal hatcheries that are lost due to flooding, warm-water temperatures, or disease, as well as to add a "novelty" factor to the tailwater fisheries.

Maybe this fish you caught came from one of the same private hatcheries... I know that they are some genetic mutation of a rainbow trout as opposed to a distinct subspecies, but that is where my knowledge of them ends.

But it is my personal theory that a fisheries biologist got very drunk one night, and thought to himself, "Wow, wouldn't it be neat to expose a trout to vast quantities of radiation and see what happens?" And the golden rainbow, our little glow in the dark trout, was the end result.

I'm pretty sure herons love them.

I seem to remember somebody posting a bunch of photos of yellow trout last Winter. Some of them were pretty big so maybe Jesse?:) Any of you guys remember?

Maybe they run them through the cooling water system of a nuclear reactor???

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

Jess,

Palomino is a coat color in horses, consisting of a gold coat and white mane and tail.

That's what they do to the Triploid Trout no? They sap them with an Ahhnold S. type of gun, and they grow to gross proportions.

Yep, Palomino is what I've always heard them called in PA. Pretty much the most unfortunate trout that could ever be. Whenever there is one present it is obvious to everyone within a 5 mile radius, and it is like that fish is the only one that exists. From the moment they hit the water they are bombarded with everything under the sun. Most don't last very long.

There was actually one in a pool that I was fishing that lasted for about two weeks once. Every morning I would wade in, and there was that yellow form cruising around down there. Then one morning I showed up and it was gone. I'm not afraid to admit I was a little bummed, kinda felt like losing a pal.

Kurt, I believe the thread your thinking of was titled "tanking big stockers with no one around to fish the floods." Although I can't name the poster.

Thanks Matt, good memory. Lets hope Josh reads this and reloads the photos.
