Detailed explanation-1: -Eutrophic water was water with high concentrations of nutrients and, by extension, a eutrophic lake was a lake that contained eutrophic water. Later the concept of trophic state was applied to lakes rather than water, and its precise definition was lost.

Detailed explanation-2: -Eutrophication is the process in which the water body becomes overly enriched with nutrients, leading to an increase in the production of algae and macrophytes. It deteriorates the water quality and depletes the dissolved oxygen of water bodies.

Detailed explanation-3: -A Highly Eutrophic Lake: A eutrophic condition is a term describing a situation where of a water body has lost so much of its dissolved oxygen that normal aquatic life begins to die off. Eutrophic conditions form when a water body is “fed” too many nutrients, especially phosphorus and nitrogen.

Detailed explanation-4: -The nutrients limiting algae growth in fresh water are different from those limiting corn growth. Phosphorus is typically the most limiting nutrient in fresh water. Consequently efforts to improve stream and lake water quality focus on reducing phosphorus losses from fields to streams and lakes.
