The end of march and all of April and May are good months to fish the Wisconsin river around the Wisconsin Dells area. Lake Petenwell and Castle Rock are some places that produce some goog numbers. The Wolf River Fremont Wi. area and Fox River area up by Winnebago and Winnebago Lake is pretty good also. Live bait on jigs is what I use at this time of year in the Rivers. Night crawlers , minnows or leeches six pound line and slow drift with the current. These are the areas I mostley fish for walleye in the spring. Hope this helped.
