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

A small, old rock wing dam has created an excellent riffle and pool in this classic trout stream.

This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive 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.

Caleb-

Let's just say you were right. Based on the cast nymphal shuck, your specimen appears to be Dannella lita (previously classified as Timpanoga lita) or Dannella simplex (previously classified as Timpanoga simplex).

Were these photos taken in North Carolina? Was the emergence event, which under normal circumstances would be in June or July, perhaps artificially accelerated as a result of the water temperature in your aquarium?

Best regards,
