largst freshwater lake without an island in the world
lots of ice up there, most likely stop in town at the local bait store and they will offer up some good advice and warn you of any bad ice areas.
its a trout lake mainly. I had a friend up that way last weekend and they got some lakers but it was tough fishing in the cold and wind. i didnt ask how deep they were but i would assume you would have to be deep to get into trout, simular to simcoe.
my friends buddy did some dammage to his sled on the south part of the lake hitting some rocks close to shore that were buried in the snow so be careful if your going out without any advice.
cheers!
