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

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 went out yesterday as the weather was forecast to be 60 degrees by 3:00. I went out on Tuesday but it was so windy I had to leave after about two hours. I need to get a stern anchor in addition to the bow anchor to keep the bow being blown up river or just spinning on the tether.

I boated seven beasts in four hours plus a big Channel catfish of 23"/24". All the bass were 18" - 21.5". In my way of thinking a 21.5" smallmouth is as rare as a 25" wild trout. They were all very strong and fought very hard, running line on a tight drag.

I saw those on Facebook. Awesome bass! What techniques are you using to chase big smallies at this time of year?

Hi Jason,

It is another of my secrets that I will be taking to my grave with me. I used to be so paranoid someone would figure out where I was that I would fudge the entire background with an editing tool. Now I figure they might kind of figure out what bridge it is but it is a piece of water about an acre in diameter and if you don't know the lay of the bottom and where the ledges and holes are they will just be wasting time. I will PM you.

Awesome Matt! I have not spent much time on smallmouths here in Michigan lately, I hope to remedy that next summer.
Mike.

Nice work, Matt.

It was great to be out - I've never had the boat out after late October. Friday was forecast to warm up by 2:00 so I went out at noon. Quite windy at first but still hooking up. Seven really big bass in just four hours is pretty amazing. In my mind a 21.5" smallmouth is akin to catching a 25" trout. It is very rare.
