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.

Here Oksrukuyik Creek flows away from the Dalton Highway toward the pipeline. It eventually grows into one of the major rivers of the North Slope, and the main drainage to the west of the Sag, but where it crosses the road it's just a small grayling stream.

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

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.

Nice work. School has me too busy to fish right now, so I'm enjoying your trips. Dries, nymphs, streamers?

Awesome photos. Do you enhance the colors with some editing software?

This trip was all streamers. Caught four pretty good browns and missed several others. The water was high from recent rains, over 2X the normal flow for this time of year.

The colors are fairly natural. All digital photos have "enhanced" colors, whether manually or automatically behind the scenes, but I try to get them as close as possible to what I remember in-person. That big brown was gorgeous.
