This past week I have been tying every BWO pattern I can get my hands on. My work has been in anticipation of dropping water levels, after massive rainfall, that has blown out everything in Oregon including the Metolius these past few weeks. I have been playing with CDC in a number of variations from Catskill dries, Parachutes, Spinners and Klink’s. This is a pretty simple pattern that is a true winner. Shown is a sized 18 and that should be sufficiently small for most needs but when it comes to a winter BWO hatch smaller is often better.
