![]() This is called isothermal water and it allows lake turnover to occur in the fall and spring.

Large, deep lakes will certainly stratify each summer, while smaller, shallow lakes may be too windblown to form distinct thermal layers.ĭuring winter, lakes de-stratify and the temperature is uniform. The extent to which lakes stratify during the summer depends on the size of the lake. The hot summer heat causes the epilimnion’s temperature to increase and create these three layers. In fact, the most intense stratification happens between late spring and early fall. Lake stratification doesn’t occur year-round. When Does Lake Stratification Occur? Image courtesy of Britannica If your lake home is in a warmer climate, these numbers could be higher. For example, on Lake Erie, the epilimnion is around 22 degrees Celsius while the thermocline is 10 degrees, and the hypolimnion is 4 degrees. The Great Lakes were created by the movement of glaciers (large sheets of ice) over land, around 10000 years ago. ![]() Specific temperatures of these three layers depend on the lake’s climate. Finally, the hypolimnion is the deepest and coldest layer that extends to the lake floor. Its main purpose is to provide a thermal barrier between the first and third layers. The thermocline (or metalimnion) is the middle layer which changes depth throughout the day. turnover, not more than five percent of the productive factory workers, or. Because it’s exposed to the sun and mixed with wind and waves, it’s the hottest and least dense layer. When lake stratification occurs, it creates three layers with distinct temperatures. ![]() Because denser materials are heavier, the cooler, denser water sinks to the bottom while the warmer, less dense water remains on top. As demonstrated by water and oil, most liquids with different densities don’t mix well. This happens because changes in temperature, during warm and cold months, cause changes in the water’s density. These stratified layers each have a different temperature, the top layer being the warmest and the bottom layer being the coldest. But when it comes to liquids (such as lakes), the colder the water, the denser. In short, lake stratification occurs when lakes form three distinct thermal layers. (This is why ice cubes float in a glass of water). However, the exception to this rule is solid water which paradoxically, is less dense than liquid water due to its unique chemical structure. This is why most substances become heavier when frozen. When liquid cools, molecules move closer together and become denser. In short, lake stratification occurs when lakes form three distinct thermal layers.
