People are out fishing as soon as the ice clears at the ramps and head out trolling cranks.In the spring the jig fisherman mostly target the reefs for spawning males and the trollers target the deeper water around the perimeter of the reefs for the bigger females.Once the water hits around 52 degrees in mid May the bite changed from a crank/jig to a spoon/ harness bite.Thats when most fish are caught in the flats.Good luck.I have found the best bite is early June.
