eutrophic lake
Quick Summary
A eutrophic lake is an aquatic ecosystem that has a high concentration of nutrients, such as phosphorus and nitrogen. This nutrient enrichment, often caused by human activities like agricultural runoff and sewage discharge, leads to excessive growth of algae and other plant life, known as water blooms. These blooms block sunlight and deplete oxygen in the water, creating conditions that are harmful to fish and other aquatic animals. In severe cases, this process, called cultural eutrophication, can lead to "dead zones" where little to no life can exist.123

- hydrologic sciencesThe history of lakes
The lake will gradually become eutrophic, with relatively poor water quality and high biological production. Infilling by sediments means that the lake will gradually become shallower and eventually disappear. Natural rates of eutrophication are normally relatively slow. Human activities, however, can greatly accelerate the process by the addition of excessive…

lakeProblems and effects…conservation of lake waters are eutrophication (aging processes), chemical and biological poisoning, and decreases in water volumes. In the former case, discussed in more detail later, the enrichment of lakes with various nutrients supports biological productivity to an extent in which the ultimate death and decay of biological material places…

lakeLake extinction…lake is said to be eutrophic. An intermediate stage in this course of events is called mesotrophy. In the case of oligotrophy the vertical oxygen distribution is essentially uniform, or orthograde. Under eutrophic conditions, oxygen values decrease with depth, and the vertical distribution is called clinograde.
