it can pullute the lake by the harmful chemicals in the water Specifically Nitrogen, high levels can kill fish and any amount will promote the growth of aquatic plants and algea, altering the lakes composition and upsetting the equilibrium, the abundance of plants and algae will promote an overpopulation of cleaning type fish which also eat the eggs of other types of fish, lowering their numbers, the overabundance of plants will also alter the circulation of the water causing the lake to become stagnant.

Better to leave it all to nature.
