Hexagenia limbata

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 specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

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 have seen many instances on the middle West Branch (From Upper Game Lands to Hale Eddy Bridge) where there will be zillions of Trico spinner in the air, and later on the water, and not a single rising fish. Yet from Balls Eddy down to where West Branch enters the main stem you will often find fish rising steadily to the spinners in pods remeniscent of the Missouri river pods of the 1990's. I've never seen Tricos above the Hale eddy bridge.
