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.

Size alone would make Stenacron unlikely, but notice the unmarked legs and that the darkest grouping of crossveins is in-between R1 and SC (Stenacron would have them between R1 and R2). Compare this specimen to the one on the Leucrocuta page--they are probably the same species.
