The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

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.

Friday I drove from the Seattle area out to Yakima, Washington, where a FEMA-run Covid vaccination clinic has so many extra doses and appointments that they're eagerly offering them to people who aren't yet officially eligible. (Washington is one of the last states to open the vaccine to everybody.) I'm looking forward to being able to safely travel on airplanes again and have at least a couple exciting fishing trips planned for this summer.

For now, I just wanted to catch the first fish of the year on my drive home via the Yakima Canyon.

Action on the Yakima was slow, and I'm consistently frustrated there by the difficult access to good spots from the road-side bank. But I did see one single rise, then caught the fish on a nymph.

My first trout of 2021! Not a big one, but a start.

It's a start!

I also collected quite a few nymphs as an excuse to have some fun with the new microscope I got last fall. The highlight was probably finding a specimen of Heptagenia pulla, which isn't known from Washington or neighboring states.
