Like all life forms, aquatic organisms also survive within a certain temperature range only. The water in the deep reaches of the dams is colder than water at the surface. When it is released suddenly in water bodies, the temperature of the water there is reduced significantly, which is very dangerous for aquatic organisms and may affect their breeding. The eggs and larvae of various aquatic animals are highly susceptible to temperature changes.
