Panfish: Perch will be in the new weed growth using a slip bobber tipped with minnows are the best bite right now. Crappies are starting to spawn on smaller darker lakes and will continue as the water warms in the larger lakes. Slip bobber rigs with hook and minnow or a jig and plastic should do the trick. If you find some warmer water in the bays or shallow flats you might get into some bluegills too.
Northern: Will still be found around new weeds pitching jig and minnows or anything that moves should be a good bet.
Walleye: These are going to be moving from post spawn areas and you will have to do a little searching they will start going to the new weed growth, maybe the sand flats off the spawning areas but pitching 1/8th oz. jigs tipped with fathead minnows or slip bobbers just over and around will catch you a nice fish fry also.
Muskies: They will be starting, in process, or finishing spawning depending on the lake water temps. Smaller baits this time of the year are your best baits to go to right now.
