Yes, the walleye fishing can be fantastic in the fall. It is my favorite time to catch them. No weeds, no bugs, no junk fish and when you catch a walleye, it is typically big. They start growing their eggs in the fall, so most of the fish we catch are big females that are full of eggs. We usually throw the biggest ones back, but sometimes catching smaller males can be tough to do that time of the year. However, if you put your boat away in late October, you are going to miss most of it. Last year, it started to get really good in late October and early November. We catch them until there are no boat ramps left to use. Here's a short video that my buddy and I did from December 2020. That year, we caught them into the 3rd week of January. It was awesome. Last year, my last trip was New Year's Eve morning. We did well. It was about 42 degrees out and dead calm. Huge line at the ramp that morning, because it was the only one still open.
