Winter stagnation at a lake occurs when the water becomes stratified into layers due to the cooling of the surface water. As the surface water cools, it becomes denser and sinks, while the warmer, denser water remains at the bottom. This stratification prevents the mixing of oxygen and nutrients throughout the water column, leading to a decrease in oxygen levels and a buildup of nutrients at the bottom. This can result in poor water quality and can have negative impacts on aquatic life. **
