This week I was down in the Catskills and stopped in to chat with Evan Lavery of The Beaverkill Angler in Roscoe, New York. The topic of our podcast is hatches of the freestone rivers of the Catskills, in particular the Beaverkill and Willowemoc Creek. These are rivers rich with tradition and also rich with a diverse insect population--although they don't have the quantity of insects seen in the Catskill tailwaters like the Delaware, they have a more diverse population so you never know what you'll see. Plus, for the wading angler, these rivers don't have drift boats thus they can be more pleasant for fly fishers on foot. In the Fly Box this week, we have these questions and more: What leader should I use for pike and muskie? How do I fish for grayling in high mountain lakes? Do trout eat moths? What fly line is best for short casts? What indicators do you prefer? How do I tell the difference between a wild and stocked brown trout? Plus a harrowing tale of an "extreme angler"
