When sewage and organic wastes are broken down, inorganic nutrients enrich the water in the water body. The problem of excessive nutrient load in water bodies is called eutrophication. To know about pollution and eutrophication level of inland stagnant water bodies in India in my study I have taken the comparative study of two ponds of Bhagalpur . The names of the two ponds are Mukhra pond and Lalbagh pond respectively. In eutrophic water body constant decomposition of blooms, lead to oxygen depletion in water. Thus, in poorly oxygenated water with higher CO 2 level where
