At the surface temperature changes fastly as compare to lower region of lakes. In lower region temperature remain unchanged for a bit more time than that of the upper surface so upper surface freezes first.

Answer:

Right when the water freezes to ice,the ice becomes significantly less dense than the water and continues to float on the lake surface. Below 4degree celcius , water becomes less dense as it colder, causing water about to freeze to float at the top.
