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.

I'm enjoying having such scenery like this within range of a quick after-work fishing trip here in Washington. I caught a whopper for this river at 11" long, but 6-8" was the norm.

WOW that scenery is insane! What a spectacular place to have as a regular, easy-access fishing spot. I thought my fishing spots were pretty (see my latest post)! Thanks for sharing.

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Second Jonathons take on your after work fishing spots! That is just some crazy beautiful scenery. And the fish are pretty cool to! My wife visited my mom and dad last year near sedonna Arizona, we took the jeep ride up to the red rock country and that was cool, but no were as nice as the country you live in! God my after work fishing spots used to be the Saginaw river for walleyes. You are very fortunate to be were your at, maybe one day I can make it out there.

Mike.

I’m new here. I have been hunting the world over for a OB-6 Galvan rod for years now. If anyone has one or knows of one please ping me. Even if you know somebody who wants a new reel and would trade up. I have the 1-5 and need the 6 to be whole.
