Hey, I fish LCO at least once a year — usually it’s with a boat, but I’ve been there a couple times on hard-water. Musky Bay is popular for both panfish and northerns. I would think Stuckey Bay would also be a good posibility for panfish, northerns and walleyes. Lots of other spots, including various bars, points and weedlines (I can give some more ideas if you wish). Just be aware of access (where can you get on the lake) as well as ice conditions (even with this weather safe travel might be tricky).
You can also call Pastikas for an ice and fishing report (sorry, no number handy).
Let us know how you do. I wish I could get up to LCO more often for ice fishing.
