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.

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
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.

Hello folks,

I'm new here, but have been fly fishing for trout for nearly a decade. I have a good buddy who is turning 40 this winter and me and some of the boys want to take him on a trip to celebrate once the weather starts to warm up a bit. Late March is looking like the time we will aim for.

We are open to traveling almost anywhere in the continental US, so what are some destinations where we could have an enjoyable time fishing in beautiful scenery that time of year and hopefully catch a few fish, too!

Thanks
Joe

If late March is your time table for the trip I would suggest the South Holston near Bristol, TN. It is a tailwater river with relatively consistent water temperatures. I personally have never fished there but a number of good friends have and they told me the BWO's are fantastic in March. Check out Altamount Anglers.

I sent you a PM with the link to Altamount Anglers.
