About 280 000 cu.km of water exists on earth in the form of lakes. Lakes are classified in many different ways to help identify similarities and differences, to assess ecosystem health, and to help establish policies and regulations. The wetland classification system for the United States adopted by the Bureau of Sport Fisheries and Wildlife in 1953 is described by Martin et al (1953) and by Shaw and Fredine (1956). Classification of rivers, especially large ones, according to their hydrological features, is rather difficult. While the number of lakes is constant, the demand for use of these lakes has increased dramatically. Lakes are classified on the basis of a) Origin b) Trophic levels c) Mixing of water. Classification of the lakes The purpose of the classification was to create lake cluster classifications according to the principle that each cluster was to have a fish species composition of its own particular type, so that each composition was to differ from all the others. In total, 5,950 lakes were classified into 15 lake classes using a two-tiered approach. Watershed .

In the fields of geology, physics and chemistry the classification is commonly based on the salinity of lake waters, hydrochemical types, saline mineral associations, mode of occurrence of lakes, relation and volume ratio of solid phase to liquid phase, origin of lake basins and useful minerals within the saline lakes (Jones et al., 1965; Eugster et ai., 1978).

ABSTRACT The Lake Louise Study Area comprises about 107 km2 (41 mi2) in the vicinity of Lake Louise, Alberta, Canada. 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). 0000001055 00000 n
