The lake in cross-section — right now

Same data as the curve above, drawn the way the lake actually sits: warm mixed water on top, the thermocline band where temperature falls fast, cold still water below. The white line is the temperature profile.

Thermal stratification — the last 12 months

Depth–time view of the whole year: reds = warm surface water, blues = cold deep water. Watch the summer layers build, then break down at fall turnover when one temperature runs top to bottom. Short gaps in the model archive are interpolated.
