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.

I caught several wild and colorful 8-9 inch brook trout in the clear little pool below this waterfall.

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.

This is a Pumpkinseed sunfish, Lepomis gibbosus, which I caught unexpectedly in a trout stream a year before I started this site.
