Rivers and streams turn over because of changes in temperature. During the day the weather is warm and the water at the top of rivers and streams heat up. At night the air cools and the heated water sinks causing the water from the bottom to rise up.
A river does not turn over like a lake does. This is because water in a river is constantly moving, unlike water in a lake. +++ Not sure what you mean, but if by turnover you mean flow, both turn their water over. With very few exceptions (in deserts, and including the Dead Sea), the water flows into a lake and out of the downstream end. You don't notice it except at the inlet(s) or outlet river because the flow is spread so slowed down over a very wide area.
usually lake are formed by rivers are formed by meanders, twists and turns in a river, overlapping and not going over the turn, filling up into a lake or pond.
