Carrie Gertrude Stevens (1882–1970) was an American fly fisher and fly lure tier from Madison and Upper Dam, Maine, and the creator of Rangeley Favorite trout and salmon flies. Self-taught in the art of fly tying, Stevens invented the Grey Ghost Streamer, an imitation of the Smelt, Osmerus mordax. Stevens' flies received national and international acclaim, and she was honored after her death with the naming of August 15, 1970 as "Carrie Gertrude Stevens Day" by the Governor of Maine.[1]
