This is no time to be on any ice. Portage Lake/The Canal has some spots that open up very easily and withought much help. Right across from the Dee Stadium nearest the other shore there is a small point that comes out from Julios proper that is very dangerous. Then just west of the lift bridge there is a sharp point that comes out that has a water navigation marker on it that is a bad area.
Out at my lake, Sandy Lake, my daughter was out on the ice right by one of our docks and wentertainment through the ice.
