IceMan- Here in Minnesota we head to the Quetico Provincial Park in Canada do do just what you are asking, fish lakers at ice out. We are unable to bring in salted smelt as the laws for transporting such bait from MN to Canada has changed. What we do is troll (in our canoe’s_ in anywhere from 9 to 15 feet of water. The lakers around here are usually really shallow at ice out. My favorite lures up the are a chrome Heddon Hot and Tot. Or a Wally diver, also in chrome. Hope this helps.
