I am from northern Mn. and I watch those lakes that are small for when the ice goes off,then I'm counting.1 day-2days-3days then it's time for me to get on the water.
I like late afternoons giving the sun ample time to warm that water up.
I'll choose spots where it's deep next to a mud flat or weedy area or submerged trees close by.
Those 1st few days it takes some looking to hone in on where they are at ,but I do find those slabs.
I use my own little 64th or 80th oz hair jig in a float n fly method.
It's great out there with no one to bother me and if they do come they leave quickly because their baits(minnow) are too big.
My advice is to use your ice tackle and small plastics,hair/maribou jigs or waxies on small hooks.
