It takes a lot of energy to melt ice. For water to turn into ice this energy has to leave the water so if the air temperature is just below freezing it takes some time for this energy to leave the water.
Water is also unusual because it becomes less dense as it freezes. Most solids are more dense than the liquid they are formed from, this means they sink. Ice is less dense than water just above the freezing point. This means ice floats. For a lake this is significant. The ice forms on top of the water providing some insulation for the water underneath. If it snows this is even more significant because snow is quite a good insulator due to the trapped air inside it. Rather than the snow falling into the water and cooling the water as it melts it sits on top of the ice and adds an insulating layer.
