Blue-winged Olives
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.

Epeorus albertae (Pink Lady) Mayfly Nymph Epeorus albertae (Pink Lady) Mayfly Nymph

Dorsal view of a Epeorus albertae (Heptageniidae) (Pink Lady) Mayfly Nymph from the East Fork Issaquah Creek in Washington

This specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.

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.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

I started with a #18 Pheasent tail and #22 Mecury RS2, nothing. I moved on to a brown Elk hair caddis size #16 (smallest I had) and danced it in the riffles, nothing. Same fly but with a dead drift, finally some action! Several refusals I watched two follow it for awhile until the drag set in. That's when I noticed the midges starring to show up, so I tied on a #24 griffith's gnat below my caddis made a cast at one of the one's who refused the caddis, because he was in a good feeding rhythm. On the second cast he shot up and took the gnat. He fought well and I landed him, it was only 13" but it had beutiful color. I probably should have fished a Black Beauty earlier instead of the RS2 and the pheasent tail, but that is my favorite prospecting rig. I seined for about 15 min and only caught empty caddis larva shucks, moss, gravel and one small green midge larva. So really not much was going on, at least were I was. I don't feel to bad though because that strech above Horse Creek has been pounded since the flood on 7/7, so I was pretty happy to land the one. I will be going out on 9/16 I'm not sure where yet, but there will be another report from Sundula coming soon (and hopefully a nice big fish pic :)) I'm thinking Eleven Mile.
