Iceaddict,
We usually go up to LOW around Christmas. By then they should have 16-24" of ice. Weather will always play a part in the fish biting, but we can usually find them. Electronics will help with seeing the fish on the bottom or suspended. Going out with an outfitter will give you a heated house, the bait and ready to fish. You will be in the houses where they think the fish are biting. If you chose to go out in your houses, they will tell you where you could set up and you have the choice to move when you want. Either way, should be a good time.
You can fish that lake from mid December all the way into mid March. the reports usually give the thickness, so an extension may be needed in some parts. Checking with the resorts website fishing reports, you can see how the bite is going. But, that is always the - "should have been here yesterday". Good Luck!
