Lakes produced as a result of the action of winds are called aeolian lakes. because, as many lake residents already know, changes in water levels can influence the water quality of their lake including the amount of algae and/or aquatic plants growing in the water, fish species and abun-dance, and water clarity. Classification suggests that it makes sense to place lakes into categories with management strategies best suited to the types of lakes found in each category. A lake is a large body of natural water accumulated in a depression. A lake’s ability to support plant and animal life defines its level of productivity, or trophic state. The water quality of the remaining 66 lakes was less than satisfactory.

Due to the absence of intermixing of the water, the bottom layer of the lake contains no dissolved oxygen and is therefore largely devoid of life except for the purple sulfur bacteria. The majority of lakes on Earth are fresh water, and most lie in the Northern Hemisphere at higher latitudes.

Maple Grove, MN 55369 Can., Can. 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).
