Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.
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.

this is a pretty good one.
Yes it is!

I really want to fish dries for Atlantics after seeing this. The refusals are awesome. Especially the one where it's mouth is open, about to take, and then quick turns away at the end. That's a big fish too!

Good footage, and brings back the best of my memories in WA ST. Same low clear water, same defined pools and tailouts, and my quarry were Summer-run steelhead in the Fall...long 6wt rods, and size #10 wet flies swung down and across on a dry line. Same outfit I now fish for trout with in Idaho.

I've watched dozens, maybe hundreds, of fly fishing videos and this has to rank right up there with the best, if not the very best, video I've ever watched. Not only is the scenery and river awesome but the footage of salmon refusing the dry flies is fantastic. What I really liked was not only does the guy have great fishing he is able to share it with his wife/significant other who knows what she is doing and obviously enjoys it as much as he does.

When the video is over you can click to see the other salmon video he posted about a year ago. It is equally as good. Especially the scene in the pouring rain.
