The Hendrickson dry fly was first tied in 1916 by Roy Steenrod for a friend named Albert Hendrickson for fishing the Beaverkill River’s famed spring mayfly hatch. The  Ephemerella subvaria mayfly and the Hendrickson dry fly eventually became synonymous, and anglers now refer to the insect by the pattern’s name. You do not have to be in the Catskills in May to fish the Hendrickson dry fly; the pattern fishes well as a general attractor in faster pocket water, thanks to a design that allows the fly to sit higher in the water column. Follow along as Karl gives step-by-step instructions on tying this essential Catskill-style dry fly.
