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.

I have been receiving decent action in the slower deep runs they are very very tenative still. I have also pulled some out of the well oxygenated plunge pools. Flies of choice have been the #22 Mercury RS2, #20 Mercury Blood Mige, #22-24 Mercury Brassie, #22-26 Black Beauty, #22-24 Mercury Midge. The flows are gradually showing an increase in flow along the entire drainage. With all the snow we got so far this year it looks like it will be another great year of trout hunting in Colorado.
