Bioglossary
Description: Process by which a lake, a river, part of a sea, etc. becomes full of phosphates and other nutrients which encourage the growth of algae and kill other organisms.

WEATHER&METEOROLOGY
is the process by which a body of water becomes rich in d:issolved nutrients through human-created or chemical processes (such as runoff laden with chemical fertilizers used in agriculture). Th:is often results in a deficiency of d:issolved oxygen, producing an environment that favors plant over animal life.
Fishery Glossary
Slow ageing process during which a lake or estuary evolves into a bog or marsh and eventually disappears. During eutrophication, the lake becomes so rich in nutritive compounds (especially nitrogen and phosphorus) that algae and other microscopic plant life become superabundant, thereby choking the lake and causing it to eventually dry up. Eutrophication is accelerated by discharges of nutrients in the form of sewage, detergents and fertilizers into the ecosystem. United Nations (1997)

Eutrophication Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
Eutrophication (Greek: eutrophia—healthy, adequate nutrition, development; ) or more precisely hypertrophication, is the ecosystem response to the addition of artificial or natural substances, such as nitrates and phosphates, through fertilizers or sewage, to an aquatic system. One example is the "bloom" or great increase of phytoplankton in a water body as a response to increased levels of nutrients. Negative environmental effects include hypoxia, the depletion of oxygen in the water, which induces reductions in specific fish and other animal populations. Other species (such as Nomura's jellyfish in Japanese waters) may experience an increase in population that negatively affects other species.

EPA Terms of Environment
The slow aging process during which a lake, estuary, or bay evolves into a bog or marsh and eventually disappears. During the later stages of eutrophication the water body is choked by abundant plant life due to higher levels of nutritive compounds such as nitrogen and phosphorus. Human activities can accelerate the process.

The processes that result in a higher concentration of dissolved nutrients in a water body.
  The increase in the nutrient levels of a lake or other body of water; this usually causes an increase in the growth of aquatic animal and plant life.
