I have caught a few, but, I was fishing for trout when I caught them. Most were caught at the base of a dam where the fast water was being released into the river and I was using a clouser or white flashy woolly bugger to match the shad that came through the dam. I do remember the walleye were a lot deeper than the trout I was catching. I would say they were very close to the bottom in the fast water release. I would cast the fly across the strong release and mend like crazy and the current would take the fly down pretty deep and then the eddy current would start bringing the fly back towards the dam. I guess it would be the under current. I can usually catch a lot of trout this way and a walleye every once in awhile. I know this is not much help, but, that is where and how I caught mine.

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
