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.

Kogotus Stonefly Nymph Kogotus Stonefly Nymph

Dorsal view of a Kogotus (Perlodidae) Stonefly Nymph from Mystery Creek #199 in Washington

This one pretty clearly keys to Kogotus, but it also looks fairly different from specimens I caught in the same creek about a month later in the year. With only one species of the genus known in Washington, I'm not sure about the answer to this ID.

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.

Summer 2015 Fieldwork

By Troutnut on June 27th, 2015, 10:10 pm EDT

This summer is intensely busy because we're beginning the first season of real fieldwork on a complicated new project. We just completed June sampling and I put together a video of what we're doing, including some really nice fish videos of feeding juvenile Chinook salmon, dolly varden, and Arctic grayling in interior Alaska:

More details about the project, including context for some of the things in the video, are available at the Drift Model Project website.

"Balloon Popper"...I like that Jason...

Looks interesting. Great video. I'm going to have to visit the other site and find out what those measuring things are you are placing in the water...?

Thanks for sharing.

The thickest midge hatch I’ve ever seen made it impossible to drive the boat without sunglasses, and even then I was constantly wiping my eyes to clear out the ones that slipped past the glasses.

Don't let Tony (Gutcutter) see this! He'll be on a plane heading your way by morning with his 4wt and his 10x tippet, and size 30 flies! :)
