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 one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.
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'm not sure why I had this specimen in the Baetidae to begin with. The eyes aren't turbinate and the hind wings are fairly large. I'm going to guess Paraleptophlebia at a glance, but I should come back to this one later. Any thoughts?

It's a pity the pictures are so fuzzy and dust-spotted up close. I took this picture before I really learned how to use and maintain my Canon 20D.
