Was on Missi today around redbridge. The ice was a good 4"+ where we were. (10' depths) Did not see anyone out towards the middle. I saw some great bank structure that I need to remember for spawning time. With the warming temps and maybe a little running water, I'd be careful and cautious. You should be able to skirt the southern edges as they are the most protected from the sunshine. Just be careful and spud as you go.
