Lake turnover is the process of a lake’s water turning over from top (epilimnion) to bottom (hypolimnion). … During the fall, the warm surface water begins to cool. As water cools, it becomes more dense, causing it to sink. This dense water forces the water of the hypolimnion to rise, “turning over” the layers.
