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.

Launching into destination number two, the bass pond at Clark's Marsh
The boys with the first fall colors, red maples of course
These lily pads were full of boils and swirls as we paddled through
Success at last!  Nice fat 16-er from the Marsh, in a deeper back channel on a #10 KBF
Prospecting for bass in the backwaters
Bass water, home of that 16-er
Wildflower bouquet in the middle of the marshlands (Bidens sp., possibly beckii?)
Serious wetland habitat, beautiful and diverse
Whorled loosestrife (Decodon verticellatus), a beautiful native relative of the evil purple loosestrife
Major habitat - this place sees a LOT of bird activity at various times, including bald eagles, trumpeter swans, blue herons, pileated woodpeckers, wood ducks, hooded mergansers, yellow-rumped warblers...
Working the bass waters
Low-rider...flipped my kayak for the first time ever
Notice the water line on my shirt
Todd continuing with Joe's lessons
Fly boxes I deployed
More flies - these are my main two boxes I carry in the sling-pack, the previous two are "add-ons" as needed
Finally...the wreckage!  This is (part of) what Joe & Todd killed during their visit...oh yes, a good time was had by all!

Here's the photos from our Marsh paddle. Note that this place is less than 10 miles from my house, in fact I can walk here in 45 minutes or drive here in less than 10...but you can't reach what we saw without a boat, the place is surrounded by marsh...but oh, the biodiversity! Didn't see much invasive either, almost all native plants. Even got a nice fish. Enjoy!

P.S. The KBF works its magic once again...

P.P.S. ALWAYS WEAR YOUR PFD!!!
No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Believe it or not Jonathon that is what the south end of Cedar lake used to look like. It was wild and beautiful and very hard to get into, huge sunfish and big pike and bass lived there. Things changed for the worse in the late 60,s when Brownell reality got permits to dredge, they did good job of screwing things up! I really miss going up to my grandparents place on the lake and how much fun we had growing up, fishing the lake and the pine river at my great aunts place. Things were sure a lot simpler then, I'm getting pretty fed up with everything going on now a days.

Mike.
