WebStratification is a natural phenome-non. In a eutrophic lake, stratification results in the loss of oxygen from the hypolimnion during the summer. When the natural fall "turnover" occurs, the dissolved oxygen (DO) of the lake usual-ly drops sharply. Sometimes this change is enough to kill or stun fish. By artificial destratification a lake can ... WebLake Properties. A lake is a dynamic water environment in which the chemical, physical and biological properties all interact and influence one another. What this means is that, the biology, or life in a lake, is a product of the lake’s physical and chemical nature. The opposite is also true since organisms within the lake can influence its ...

Web1 Apr 2024 · With severe thermal stratification in a lake, the quality of drinking water also can be adversely affected. For fisheries managers, the spatial distribution of fish within a lake is often adversely affected by thermal stratification and in some cases may indirectly cause large die-offs of recreationally important fish. WebA WARM lake has more of a density difference between the epilimnion and the hypolimnion. The greater the difference in density between layers, the stronger the stratification 'stability.' In a COOLER lake, the temperature (density) of the surface water is closer to being equal to the bottom water.
