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.

Normally I do quite well here in early season. However it is possible that I just never went this early before. Only browns and pretty stocked brookies and a small amount of wild browns. It appeared that the stocking performed early in March left much to be desired. Some sections appeared almost barren of fish and other small areas had little pockets of 5 - 6 12" - 14" fish.

Upstream of the trail from the parking lot there is one large pine tree across the creek that wasn't there last summer. Also lots of blowdowns along creek edge. Well downstream there is a large log jam of about half a dozen downed trees across the creek making it impassable while wading. Any rod longer than 6 1/2' and you'll be testing your patience!

Here is where I started - (summer photo)
