Salmonflies
Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

I was not fishing, but happened to be at an unrelated social event on a hill above this tiny creek (which I never even saw) when this stonefly flew by me. I assume it came from there. Some key characteristics are tricky to follow, but process of elimination ultimately led me to Sweltsa borealis. It is reassuringly similar to this specimen posted by Bob Newell years ago. It is also so strikingly similar to this nymph from the same river system that I'm comfortable identifying that nymph from this adult. I was especially pleased with the closeup photo of four mites parasitizing this one.
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.

The zebra trout: Trout that resisted the last glaciation.
FEATURES OF OUR NATIVE TROUT, ZEBRA TROUT:

It has many small black and red circles surrounded by a white halo and also has four dark stripes crossing his Body.

Great adaptation to our climate: large avenues, water stress and high water temperatures.

In result of the adaptation she is suspicious to predators.

The wide avenues of water and the rivers rocky mountain background seems they cause the morphology of trout oversizing their pectoral fins.

The other main feature of this type of brown trout is its speed when attacking flies.

Great power.

More than 10 spots on the Operculum.
