My goal this winter season is to catch a giant walleye
That’s everybody’s goal. Easier said than done.
People aren’t just going to tell you a spot, especially on the internet where anybody can read it. Post around enough, and you can start to gather some information that you can use to help you out. Types of structure to look for, etc.
My advice for a big walleye through the ice in the metro area is to fish the last hour of sunlight into the first hour of darkness. Have some different structure near you. Study some lake maps. Lake Minnetonka is an outstanding fishery in the metro area, but it can be intimidating. Pick a bay, and treat that bay like an individual lake, essentially treating Minnetonka like 20 small lakes rather than 1 large lake.
