Lake stratification
WebbLake Stratification and Mixing Many of our Illinois lakes and reservoirs are deep enough to stratify, or form "layers" of water with different temperatures. Such thermal stratification occurs because of the large differences in density (weight) between warm and cold waters. Density depends on temperature: water is most dense (heaviest) Webb24 juni 2024 · When lake stratification occurs, the hypolimnion is too dark and dense to allow oxygen flow. This is because its low depths are divorced from the wind and sun …

Webb21 apr. 2024 · New research shows that lake “stratification periods” – a seasonal separation of water into layers – will last longer in a warmer climate. These longer periods of stratification could have “far-reaching implications” for lake ecosystems, the paper says, and can drive toxic algal blooms, fish die-offs and increased methane emissions.
