Anybody have any advice on walleye fishing during a cold front? Heading up just outside bwca tomorrow through sunday. Thanks

Dawn and dusk. Go either very slow with a small bait/lure, like a half crawler on a sixteenth-ounce jig (under a bobber maybe) OR big and fast for reaction bites. Rip jig plastics for example.
Nap or fish for bass/pike is another remedy.

Do not overlook deep water. 20 to 30 feet depths close to some nearby structure.

Thanks for the info, the cold front shouldn't shut down the bottle bass. JB
