I fish Lake Wisconsin here in southern WI. I also fish some of the other local lakes like Mendota and Waubesa. If fish up the Dells and have fished Lac Seul for years.
I have to say that from what I have seen since I started seriously fishing walleye about 1982 is that slots make a huge difference in quality of the fishing for walleye. I would love to see it applied to all species.
I saw Eagle Lake in Ontario at its worst and headed up the road to Lac Seul, saw that as it recovered and now it is a special place to me. Lake Wisconsin is a place I find myself fishing more and more because of the quality of the fish available.
I sure hope IDNR and the WI DNR put these slots in place in as many places as possible.
