Thermal stratification in a temperate lake refers to the vertical temperature layering that occurs mainly during the summer season due to differential heating of water. It is caused by solar radiation warming the surface water while deeper layers remain cooler. This phenomenon divides the lake into three distinct layers. The epilimnion is the uppermost layer, warm and well-mixed due to wind action. It has high oxygen content and supports abundant aquatic life. Below it lies the metalimnion or thermocline, a transition zone where temperature decreases rapidly with depth,
