Scientific definitions for eutrophication

eutrophication
[ yōō-trŏf′ĭ-kāshən ]

The process by which a lake, pond, or stream becomes eutrophic, typically as a result of mineral and organic runoff from the surrounding land. The increased growth of plants and algae that accompanies eutrophication depletes the dissolved oxygen content of the water and often causes a die-off of other organisms.
