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.

Of all the pools I've fished, this one was most deserving of the colorful little brook trout it held.

Onocosmoecus (Great Late-Summer Sedge) Caddisfly Larva Onocosmoecus (Great Late-Summer Sedge) Caddisfly Larva

Lateral view of a Onocosmoecus (Limnephilidae) (Great Late-Summer Sedge) Caddisfly Larva from the Yakima River in Washington

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.

Last year after the big floods (southwestern wisconsin) this dam was knocked
out. The area was about 5 feet shallower. ALL the
trout were centralized in three areas. Just at the end
of view in the photo.....

Last day of season....I saw a commotion way in the
foreground of this photo...

I went up to see what I thought was a beaver dinking
around. As I got closer i was WOWED. It was giant
brown chasing down little brookies in the shallows and
eating them. I got my camera out a little to late. The
brown was minimum 28 and fat. 3/4s of its body was
outta the water when it was chasing the brookies...saw
the brookies running like minnows....too far away to
get good movie.

The water is back up to the level in the photo. It is
about a 100 yards stretch....two beaver dams make it
so it can't leave. I usually don't chase brookies
because they aren't much of a challenge...Will this
spring
