Freshwater lakesMost of the lakes in the world are freshwater lakes. 0000001456 00000 n Canada, Finland and Siberia contain most of the fresh water lakes. Clearly, the classification of lakes in the WFD must eventually be based on biological indicators, but TP is the main environmental stressor and the primary determining factor for numerous bio-logical variables, and it is also used in present-day lake classification (Vollenweider & Kerekes 1982; Wetzel 2001). International Journal of Salt Lake Research 5: 35-44, 1996. 0000061913 00000 n Homogeneity of the lake types is given by the mean values* for indices (1 or 0) allocated to categories of each descriptor.
