The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

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.

Dinking around on a small stream

By Troutnut on September 28th, 2020

On September 29th I went up to the mountains to sight in my hunting rifle in advance of deer season. However, the custom ammunition I ordered was the wrong length and wouldn't fit into the chamber, so that job ended quickly. (I won't name the company, because they bent over backward to make it right, and I got it fixed by hunting season.) As a consolation prize to make the trip productive, I drove to a nearby stream and played with the colorful little rainbows and cutthroat trout on perdigon nymphs. As a bonus, I caught a striking and unusual species of Siphlonurus mayfly.

I found this specimen and saw a few more of its kind during midday on a small, steep, rocky creek fairly high in the Cascades, different from the previously reported habitats of its species.

Man those are some pretty fish. Small streams like those are near and dear to my heart. I could fish small stuff like that each and every day. What set up do you like to use on streams like that?

I use a lot of different setups on small streams. I have one dedicated rod for them, an Orvis 7' 4-weight, and I stick with that one when fishing in tight quarters. This particular small stream flows through a really wide-open, rocky channel with lots of backcast room, and I wanted more practice with my Euro nymphing rig, so I used that.

Yes, beautiful fish! Well done.

Nice little stream with pretty fish! And yeah, a 7-footer is perfect for that situation, maybe even a 6 1/2-foot 2-weight (I have a couple). Thanks for posting!

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

Has anyone tried using nanofill material for leaders??!

Why would anyone want to do that? Nanofil is a Berkley braided line of very strong break strength to diameter ratio. However it is not transparent like nylon or fluorocarbon so while it is thin it is clearly visible in the water. Additionally Nanofil braid is super slippery line and a normal clinch knot or Davy knot won't hold. I would never have the patience to tie a Palomar knot every time I wanted to change my fly.

Modern nylon and fluorocarbon are amply strong enough to land large trout and other game fish on surprisingly thin and light tippets. Learn to use them and know their advantages and limitations.
