After Thienemann. establishes an important classification of lakes on the basis of depth. The location of the thermocline differs in different lakes: in the Mans- feld Lake, in July, it lies at a depth of 1-3 m.;6 in Lake Sakrow near Potsdam (Fig. 100) it lies at 6-8 m.;7 in Lake Constance (Fig. 99) between 16 and 20 m.;8 in Lake Madue (Fig. 93) between 18 and 22 m.,9 and at a similar depth in Lake Cayuga; in Lake Mendota in 1906, between 7 and 14 m. This type of temperature stratification applies to the open water of deeper lakes. In the shore regions of such waters, and in shallow lakes, especially, if they are exposed to mixing by means of the wind, the temperature is more equally distributed through their depths; thus the greatest difference between the temperature of the surface water
