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.

This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.
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.

Here I'm looking through the sampling net for interesting nymphs, some of which ended up on this site.

Here I'm tying on a fly in the middle of a warm summer day.  Despite the conditions, the trout responded well.

This tail end of a large glassy flat holds many nice rising trout most summer evenings, and it's extremely demanding of both stealth and fine casting.

Lone tree on a rock in the middle of Big Lake. Fittingly, Big Lake is the largest of several short wide spots in the upper Brule River.

This colorful brown was my dad's first nice trout on a dry fly.  It was also the best of the day, taken with a nice cast after doing some slightly crazy wading through silt and deep water to get into position.

Good trout, both browns and rainbows, sometimes reside in the calm pockets alongside roaring rapids like these where most of the canoe traffic shoots quickly past.  Few fishermen stop to cover these areas.
