The Catskill Mountains of New York are where American fly fishing was invented. Not the sport itself — English anglers had been fishing dry flies for decades before the first rods appeared on the Beaverkill — but the distinctly American approach to it: the flies, the casting style, the philosophy of fishing to rising trout with precisely imitated naturals. Everything that most American fly fishers think of as tradition traces back to a handful of people on a handful of rivers in the hills southwest of the Hudson Valley.
The Rivers
The Catskill trout fishery is built around two river systems that drain the southwest Catskills into the Delaware River basin. The Beaverkill flows through Livingston Manor and Roscoe ("Trout Town USA") before joining the Willowemoc at Junction Pool — perhaps the most storied piece of trout water in the United States. The Willowemoc Creek drains from the north and west, meeting the Beaverkill in Roscoe, where both run public for several miles.
The Neversink River, running south through Sullivan County, was the home water of Theodore Gordon and remains one of the most technically demanding Catskill streams — clear, cold water with extremely selective wild brown trout.
The Delaware River system — both the East Branch and West Branch — forms the western boundary of classic Catskill fishing territory. The West Branch below Cannonsville Reservoir and the East Branch below Pepacton Reservoir are tailwaters with exceptional wild brown and rainbow trout populations, and both are widely considered among the best dry fly rivers in the Northeast.
The Catskill rivers are public water. Most of the classic fishing on the Beaverkill, Willowemoc, Neversink, and Delaware branches is on publicly accessible sections — state-owned land, easements, or water open to licensed anglers. New York's Fishing Access Map (available at dec.ny.gov) shows current access areas on all major Catskill streams.
Theodore Gordon and the Birth of the American Dry Fly
Theodore Gordon (1854–1915) is the central figure of Catskill fly fishing history. A sickly bachelor who lived most of his adult life in the boarding houses of Sullivan and Ulster Counties, Gordon spent decades fishing and tying flies on the Neversink and Beaverkill, developing the principles that became the Catskill School of fly tying.
Gordon began his fly-fishing life as a wet fly man, in the English tradition. In 1890, he received a package from Frederic Halford, the English dry fly authority, containing a set of Halford's dry fly patterns and a copy of his theories. Gordon spent the next 25 years adapting those ideas to American conditions — specifically to the faster, harder water of Catskill rivers and the mayfly species that inhabited them.
The result was a new style of fly. The Quill Gordon — tied with a stripped peacock quill body, divided wood duck flank fiber wings, and stiff dry fly hackle — became the archetype. The pattern was designed to ride high and dry in moving water, present a clean silhouette visible to both fish and angler, and survive repeated casts without absorbing water. It remains in production today, essentially unchanged.
Gordon never published a book. His legacy survives through letters (primarily his correspondence with English angler G.E.M. Skues) and the recollections of the anglers and tiers who knew him. John McDonald's The Complete Fly Fisherman: The Notes and Letters of Theodore Gordon (1947) remains the essential primary source.
The Golden Age of Catskill Tying
Roy Steenrod
Gordon's successor on the Beaverkill
Roy Steenrod fished and tied with Gordon in his later years and became the primary transmitter of Gordon's methods to the next generation. Steenrod created the Hendrickson pattern — named for his friend A.E. Hendrickson — which remains one of the most important dry fly patterns in American fly fishing. The Hendrickson (and its female imitation, the Red Quill) matches the Ephemerella subvaria hatch that opens the major Catskill hatches each April.
Harry and Elsie Darbee
Livingston Manor, NY — the center of Catskill tying
Harry Darbee and his wife Elsie operated a fly-tying operation out of their home in Livingston Manor for decades, supplying flies and genetic dry fly hackle to the American fly fishing market. Harry was a skilled tier and an opinionated conservationist who advocated for wild trout and clean water long before those were popular positions. Elsie tied as many flies as Harry — their collaboration was one of the most productive in American fly tying history.
Walt and Winnie Dette
Roscoe, NY
Walt Dette began tying flies in the 1920s and, together with his wife Winnie, operated the Dette Trout Flies business in Roscoe through the mid-twentieth century. Walt was known for perfectionism in the Catskill style — his proportions were exact, his bodies precisely tapered, his hackle fibers counted and even. The Dette operation continued after Walt's death, with Winnie and later their daughter Mary maintaining the tradition.
Rube Cross
the innovator
Rube Cross was a less formally trained tier than Gordon's direct successors but was equally influential, developing patterns like the Dun Variant and the Fan Wing Royal Coachman into their most recognizable forms. Cross was also a gifted teacher and prolific correspondent, spreading Catskill techniques widely through the mid-twentieth century.
The Catskill Method: What It Is
The Catskill style of fly tying is defined by a set of proportional standards and material choices that produce a fly suited to the specific conditions of Catskill rivers:
Upright divided wings — typically wood duck flank fibers, mallard flank, or mottled turkey, set upright and divided to form a V-shaped wing profile. This provides a distinctive silhouette visible to both fish and angler.
Stiff dry fly hackle — wound in front of the wings, the hackle fibers support the fly on the water surface. The quality of the genetic dry fly hackle is what makes a Catskill fly float — soft, webby hackle absorbs water; stiff, glossy hackle repels it. The quest for better hackle drove American breeders like Henry Hoffman and Tom Whiting to develop the genetic hackle varieties that dominate commercial fly tying today.
Slender, tapered bodies — quill bodies (peacock eye quill, stripped hackle stem) or dubbed fur bodies with precise taper, tied sparse rather than full.
Proportions over decoration — Catskill flies are functional, not ornate. The form follows function: every element exists to float the fly, present a silhouette, or hook the fish.
Key Catskill patterns still in common use: Quill Gordon (#12–#14), Hendrickson and Red Quill (#12–#14), March Brown (#10–#12), Light Cahill (#14–#16), Dun Variant, Fan Wing Royal Coachman. Each imitates a specific mayfly (or impressionistically suggests several), and each remains a first-choice fly on the streams for which it was tied.
The Catskill Fly Fishing Center and Museum
The Catskill Fly Fishing Center and Museum in Livingston Manor, New York, is the institutional home of the Catskill tradition. The museum holds one of the finest collections of vintage Catskill flies, rods, reels, and angling artifacts in the world — including flies tied by Gordon, the Darbees, the Dettes, and dozens of other historical tiers. The center is open to the public, hosts tying events and educational programs, and sits on the Willowemoc Creek just upstream from its confluence with the Beaverkill.
A visit to the museum paired with a day on the Beaverkill or Willowemoc gives context to the tradition in a way no book can fully replicate. The flies in the cases are small — you'll need to lean in — but the precision is immediately visible and remarkable.
The Tradition Today
The Catskill rivers remain excellent trout fisheries, though the character of the fishing has shifted. The wild brown trout populations on the Beaverkill's public water are smaller on average than in Gordon's era, a function of increased pressure and reduced streamflow. The Delaware tailwaters — both branches — fish better today than the classic Catskill streams by most objective measures, and have attracted their own tradition of guides, tiers, and regulars.
The Catskill style of tying is experiencing a revival among enthusiasts who value the aesthetic and the history, even as production fly tying has moved toward materials and techniques that produce a different kind of fly. Learning to tie a proper Quill Gordon or Hendrickson is an exercise in understanding why those proportions exist — it's as much a lesson in entomology and hydrodynamics as in craft.
