The Doc Spratley attractor fly was named for Dr. Donald A. Spratley and was first tied in the 1940’s by Dick Prankard of Mt. Vernon Washington. The Doc Spratley has become a well-known staple for Pacific Northwest and BC Interior still water anglers and has been gaining popularity in other locals. Larger sizes of the fly are generally fished as dragonfly nymphs or caddis pupa while the smaller sizes can be seen as a chironomid fly. Either way, the fly has a long life and has been consistent in bringing rainbow trout to hand.
There are a few main color variations of the Doc Spratley fly. Black, purple, yellow, red, and olive green bodied Doc Spratley’s are the most often variations seen in the fly shop and a beefier steelhead version can sometimes be found. A full peacock version is also a favorite of anglers that tends not to get shared. The bodies can be tied using floss, wool, dubbing or peacock herl.
