Bureau of Labor Statistics reported today. This is called isothermal water and it allows lake turnover to occur in the fall and spring. 27 Ohio Job Openings and Labor Turnover July 2023 Ohio had 321,000 job openings in July 2023, compared to 351,000 openings in June, the U.S. 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. 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. 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. But when it comes to liquids (such as lakes), the colder the water, the denser. (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. 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.

Sewing machine operators had a location quotient of 1.0 in Cleveland, indicating that this particular occupation’s local and national employment shares were similar. In short, lake stratification occurs when lakes form three distinct thermal layers. For instance, tool and die makers were employed at 3.6 times the national rate in Cleveland, and engine and other machine assemblers, at 3.5 times the U.S. Image courtesy of Dickinson County Conservation Board.
