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.

Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva

Dorsal view of a Glossosoma (Glossosomatidae) (Little Brown Short-horned Sedge) Caddisfly Larva from the Yakima River in Washington

I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.

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.

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)
