Lake Scharmützel (next to Bad Saarow east of Berlin) is the second biggest lake of the federal state of Brandenburg. It is approx. 10 Km long, 1,5 Km wide and is up to 29 Meters deep. From time to time, the lake does freeze over in winter and is used for all kinds of leisure activities, from skating to ice-fishing to warming yourself at the Gluehwein stands on the lake. Mind you, a frozen Scharmützel lake is a rare event, especially as the winters tend to get warmer every year. Not surprisingly, this photo was taken in 2006.
