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.

Dorsal view of a Skwala (Perlodidae) (Large Springfly) Stonefly Nymph from the Yakima River in Washington

This Skwala nymph still has a couple months left to go before hatching, but it's still a good representative of its species, which was extremely abundant in my sample for a stonefly of this size. It's obvious why the Yakima is known for its Skwala hatch.

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 15" brown trout took a small emergent sparkle pupa on a large Catskill river.

Here's an underwater post-release picture of a 15" brown trout I caught in a clear Catskill river.

This is one of the most famous trout streams in the country.

The Beaverkill River in New York

Here's the most famous pool in the world. I was shocked that the fishing was so good--I had expected such a legendary place to be overfished. While it certainly sees a lot of pressure, it's still possible to have the whole 300-yard pool to yourself once in a while, and in the fall it doesn't get anywhere close to the combat fishing it sees during the major hatch seasons. It supports a terrific population of the most picky free-rising trout I've ever seen.
