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.

That's a beauty, Matt! How long did it take you to subdue him? I got one almost that big - 19.5", but yours looks fatter - this past summer on my 3-weight and I was certain I was gonna lose him, felt like I had hooked a mule! Took me a good fifteen minutes to bring him to the net...

May I inquire, what fly?

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

P.S. Glad to hear that Bob Clouser's home waters are still producing great big fat smallmouth!

The river has been fishing very well the past three years in the Fall. During the June - August period I can't buy a smallmouth but in the Fall they come in near shore busting shad and shiners and feeding up for the winter.

The big boy took an honest ten minutes to land - it jumped repeatedly and ran much line on a drag that is quite tight. There is a strong current and a loose drag would have a fish that big 200' down river in no time.

I went out again today for four hours and landed over a dozen to 20" most were 15" - 18".

Spence - The fish actually take pity on an old man like me so get on my hook as a favor.

Anyone who knows me, or visits this site, will have seen pictures of large trout, bass, and steelhead that I've caught. I'd never resort to photoshopping when the real thing is just so much better. Here is another example of a recent successful outing.

You might be able to see the Black stone fly still in the upper right jaw.

Matt, I had the benefit of NO current when I landed mine, as it was off of my friends' dock in a lake - in which I had never caught any smallmouth of any size, and it was in fact the biggest fish I have yet landed from this lake, besides my largest flyrod-caught smallmouth (by far, next biggest was 16" from 2007) and in fact largest smallmouth of my life on ANY tackle!

What rod and fly were you using? Just curious if it was in fact a Clouser Minnow...

Matt,

If this is the case they must be feeling real bad for you old-man because they are sending their big boys out to smack your offerings!

I think it's more likely they have seen you so many times that they know you will land them properly, ASAP in other words, and after posing for the camera will be returned to the stream no-worse-for-wear. I use to joke, being a vegetarian, that they drew straws when I was fishing and they reassured the "loser" that he had nothing to worry about..."He's going to let you go...Trust us...No trip to the frying pan." :) They would then be able to sit it out until everyone else had taken their turn. Kind of a Russian roulette of the trout stream.

I was in to "schooling" the fish...I would pat them on the ass and say, "Better be a little more careful next time kid-o! The next fly you see may not be attached to my leader! You will find yourself floating in some warm butter instead of a cool clear trout stream."

The sections of the Au Sable we fish are in Crawford County...My fishing buddy and I would let out a war cry when we passed the County sign on the highway on our way up and someone would shout out that all the Brown trout in Crawford County somehow knew we were back and were tucking themselves a little further up under the undercut bank...Hey! We were younger then and a great deal more excitable.

Nice job though Matt showing the young whipper-snappers on this site that we old-timers earned that gray in our beards and those monster fish. It's all about time-on-the-stream, eh.
