This classic trout pattern was named after a Dr. Donald A. Sprately from Mount Vernon, Wash., and originated by Dick Prankard in the late '40s or early '50s. It is also known as the Sprately and the Doc Sprately.
Think of this one when trout are feeding opportunistically. Use it for sea-run cutthroat or stillwater rainbows in the late fall. Try it on a fluorocarbon tippet and a floating line or, better yet, use a slow-sinking line.
Tie the Doc Sprately on a long shank No. 8-10 hook. For the tail, use gray hackle fibers. Wrap the body with black wool and a silver tinsel rib. For the collar, employ grizzly hackle. Tie in a pheasant tail wing and finish with a peacock herl head.
