Hex Mayflies
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 species was fairly abundant in a February sample of the upper Yakima.
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 the underside of a "lunker structure", a manmade undercut bank where trout love to hang out. It's amazing how much I've seen the trout use these things. I've also noticed that the best trout populations I've seen are in streams where lunker structures have been installed.
