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.

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.

A little quick bug collecting in the Cascades during runoff

I was in the area of the Icicle River on June 3, so I toured the scenery and admired the power of the river ripping down through the mountains as snowmelt peaks in the high country. I wanted to try some new photography gadgets, so I collected a few nymphs from the river and a tiny, probably fishless tributary called Chatter Creek. It took a long time just to find somewhere I could safely step onto gravel in the river to sample, and the creek that is probably ankle-deep most times was waist deep.
