I bet if it's got any ice at all it's extremely sketchy. Definitely try and get a hold of someone local. Temps just haven't gotten cold enough yet this year.
The only walleye bait I've used on my last 2 fly-ins are vertical jigging spoons. I brought about half a dozen of them. Later in the fall they're deadly and sometimes the only thing they'll bite. Full sized Williams and the Bluefox rattlin spoons work great. No need to bring 500lbs of jigs with you.
