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.

I was not fishing, but happened to be at an unrelated social event on a hill above this tiny creek (which I never even saw) when this stonefly flew by me. I assume it came from there. Some key characteristics are tricky to follow, but process of elimination ultimately led me to Sweltsa borealis. It is reassuringly similar to this specimen posted by Bob Newell years ago. It is also so strikingly similar to this nymph from the same river system that I'm comfortable identifying that nymph from this adult. I was especially pleased with the closeup photo of four mites parasitizing 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.

Has anyone in the Central New York area fished Grout Brook? It runs into one of the south ends of the finger lakes, Skaneatles Lake, and from what I have herd gets a nice run of fish in the fall and spring.

I've read good things about it in a few of the books about the area (small and brushy but with a decent population, I've heard) but I never got aroudn to fishing it while I was there. I never got optimistic about any of the lake run fishing around there because the runs were all so scarce, and I'd rather try for choosy insect feeders where I know I can find them rather than searching high and low for something big from the lake to hit a streamer.

What you said is exactly why I haven't fished it either. I went there one time just to check it out and it is a SMALL stream - not as wide as a car in some spots. We are supposed to have a bit of rain this week along with cooler weather, so hopeuflly there will be some fish.
