Salmonflies
Pteronarcys californica

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

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.
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.

This road was easy cruising to the river when it was dry. An unexpected thunderstorm made getting back a major challenge. Great tires and 4WD only go so far when the tires are completely caked in slick wet clay. Fortunately there were no really steep hills or dangerous drops off the side of the road.

It's amazing what a thunderstorm and a reach of clay badlands can do to the clarity of a normally crystal-clear trout stream.
