Abstract:
The process of aging of lakes is a serious problem in India because of eutrophication. Besides natural eutrophication, eutrophication due to various anthropogenic sources as a result of socio-cultural activities is a serious issue. The paper reviews different aspects of eutrophication, its impacts on water quality and aquatiebiota. Lake classification based on nutrient management models is described to evaluate lake conditions and associated rejuvenation methods. The positive correlation between different groups of algae has been observed in relation to physico-chemical conditions of soil-water of lakes. Lake assimilative capacity in relation to water quality and sediment water interactions is illustrated for better understanding of the restoration of lake. Methods for rejuvenation of lakes are described emphasizing on the reduction of nutrients through anthropogenic activities.
