Fertilizer flow down in the river along with the water Due to this after some time the oxygen content of water was depleted. So we can say that nutrients enrichment of water bodies leads to overgrowth of green plants (called algae) which results in eutrophication.

During rains fertilizers used for agriculture spreads to the lakes. Fertilisers contain phosphates and nitrates by which water body became enriched with these chemicals. These chemicals promote excessive growth of aquatic plants and the surface of the water was completely covered with plants. (eutrophication)

Depletion of light in the water body and insufficient availability of dissolved oxygen and nutrients resulted in the death of fish.
