Catskill Fly Fishing Heritage · New York State Scenic River
Birthplace of American fly fishing. The Beaverkill and its tributary, the Willowemoc, are the Catskill streams where Theodore Gordon invented dry fly fishing in America in the 1890s. Generations of legendary fly tiers and anglers — the Dettes, the Darbees, Lee Wulff — refined their art on these riffles. Wild brown and brook trout in classic pool-riffle-run water.
