Where are you thinking of fishing for them, we might be able to get you a little closer info, though the aforementioned are great places to start if you are in the western part of the state.
there taint a walleye within a hunnert miles of here…. ok.. well maybe there is.. but truly its not great winter walleye fishing anywhere near where I live.. they can be had.. but its not easy.. your better off going for panfish if your just looking for some nice eating….
