Sounds like you are headed in the right direction. Rigging and Slip bobbering should be the way to go this weekend.
If you don’t already have one, a Tutt’s Walleye Wiffer map is invaluable. Most of the spots marked with GPS coordinates will have fish…and boats as well. These are great general areas to concentrate on. Don’t be afraid to check out some of the deeper gravel areas 19-27 feet during the day. Find them on your electronics, then fish em’
Good luck, and let us know how ya do.
