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.
Fishing is not a hobby, its a science. I just moved to Ohio from Ft. Lauderdale, so fishing is nothing new to me, however trout are. Any help surrounding steelhead would be fantastic. Tight lines everyone!
