Dick Prankard of Mt. Vernon, Washington, originated this fly about 1949. The fly was named after Dr. Donald Spratley who was a dentist in Mt. Vernon. He and his friends used it for fishing the lakes in British Columbia that had large caddisfly hatches.
Terry Hellekson Note
I was first introduced to this pattern in 1963 on northern Washington's Ross Lake where it was the only fly we used for a full week. The version of this fly that we were fishing with had a peacock herl head and grizzly hackle barbs for the tail. I later learned that it was proving successful for both summer and winter-run steelhead. Needless to say, you will find a great many variations of this pattern and I have found it tied up to size 1/0.
