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.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.
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.

Sundula has attached these 10 pictures to this report. The message is below.

This is a picture of Cheesman Resevoir ther are burnt trees as far as the eye can see from the Hayman Fire
This is a picture of Cheeseman Dam
Cheeseman Canyon is full of huge granite boulders
As you can see the the trees in the canyon were not touched by the fire it's pretty amazing because everything around the canyon was.
This is the pool where I landed my first two Cheeseman Canyon trout
This is a photo I took in the Spring I am attaching as another example of the beauty of the canyon.

The fishing was great today with "Traditional" RS2s #22 dropped under a Mercury RS2 #18 - 20. I finally landed some of the "super selective trout" out of Cheeseman I have fished it 8 times and never landed any trout I have hooked 2 prior but my net was left empty. I was so excited, I could have left today after netting one, but four trout out of there in my opinion is fantastic! The action was good the whole time I was there I missed a few not so subtle strikes, and had two throw the hook and one I played in a deep pool and it snapped my tippet after only 15 seconds. The best fishing was in the deeper tailouts but I hooked one in about a 14" riffle as I was making my way to the bank to move up stream. It was a virtual cornacopia of hatches, the tricos would come off then the baetis, then I would see some caddis then more baetis, the midges were coming off all day. I am attaching pictures but they are not of the best quality but I know I like seeing photos of your guy's fish, and the beauty of Colorado is something I like sharing with all of you. Sorry again for the sub par photos but you get the idea :)

Well... the photos are good enough to make me wish I lived in Colorado! So you're doing something right.

Great photos! I have to get to Colorado someday. "It's so beautiful there" --I hear that time and time again.
