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.

I don't know how many of you guys knew about this (probably everyone but me!), but the USGS recently began production of enhanced topo maps. They've currently mapped about half the states and are at varying degrees of completion with each. They've released each 7.5' x 7.5' quadrangle in PDF format using layers to show different types of data (added to this most recent release for the first time is a hydrographic layer!). You can turn on or off each type of layer with a simple toggle. The quadrangles are available for free download. I found they are each 10-20 MB in size. There is a toolbar you can also download (called TerraGo) that will enable you to interact with and personalize each map by marking spots, making notes, measuring distances and areas, and even track positions using your GPS. This seems like just the sort of tool a flyfisherman would find really useful. I'm pretty excited about it - Pennsylvania just got finished! Check it out here:
