The center of the lakes upper most column of water is a much warmer temp than the bottom of the lake and takes longer to freeze, partly due to more sunlight and the volume of water involved.
Why do pond edges not freeze?
As the ice layer forms on the surface, it acts to insulate the water below it, reducing the amount of heat the air can remove, but the ice doesn't form on the pond bottom, so it continues to receive heat from the earth. So the pond never fully freezes if it is deep enough and the winter short enough.
