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'd like to get a species for this if possible.This species is found in the Russian River. It is found in slow water, usually among the roots of torrent sedge and floating ludwigia. It is most common from February through May.

I like the choice of decoration - everyone different!
