I've seen similar stuff caught in limbs along brookie streams. And the old small Colorado blade, red beads, and a two hook gang with a worm is common on the Tug hill, same principle but with a pork chop.
The late Leigh Condit, and Tom McGill of Rochester, used to fish single hook in-lines in the Genesee with great success. Tom told me he quit Salmon fishing with them when the snaggers on the other side of the river figured out that they could wait for him to hook up, cast across his line, let the cricket slide to the fish, set hard, and get a fish, and a spinner, as he fished a lot lighter than 30#, and he hooked up a lot more than the snaggers on early kings.
The key with those spinners is an upstream cast, tighten just until the blade starts to work and then lead through the drift and swing as if you were drifting eggs. When the blade gets going quick, drop some tension or time to reel in. Lose your concentration during the slow rotation part of the drift, kiss another lure goodbye. The strikes in the winter from chrome will nearly take your arm off. Same thing works with a hotshot and pencil lead, but the losses are even more painful.
