Perch have traditionally moved in closer to shore in the fall,but not so much the walleye.The walleye are closer to shore in the spring than now.The walleye do move up in water column as the water cools and move up onto some reefs.We have caught walleye trolling a few miles off Huron in the past though.They also catch walleye fairly close to shore in November and December.But those months can have a lot of windy weather.Have to pick your days carefully and fish on light southerly days.
