How deep has the Leman brew reached?
February 6, 2021: The stirring reached a depth of 135 m. Compared with January, the mixing layer has thickened by 15 m and cooled by 0.4°C. The little cold snap we've just experienced wasn't enough to stir the lake's waters any more than that.
What do the weather forecasts say? The next few weeks will be decisive for mixing, but the weather forecasts are rather clement and do not predict a harsh end to winter. Hopes of a complete mixing of the lake waters this winter are therefore all but dashed.
