I don't ice fish large lakes like that. The lakes I fish don't have that problem. The worst thing that happens is the runoff from the melting snow melts the ice right at the shoreline. If it melts enough, you need to walk on some boards to either get on or off the safe ice. When you are dealing with a lake that doesn't freeze all the way across you can get ice flows breaking off. When you have a lake that freezes all the way across, generally the edges melt before the middle and that restricts access so you don't get people drifting around. I was hoping to go ice fishing Monday the 15th, but not sure what the ice conditions are going to be. I'm sure the lakes will refreeze before the final thaw, just not sure when.
