Eutrophication Eutrophication is the natural process by which waters (lakes, rivers etc) become excessively enriched with nutrients, typically nitrogen and phosphorus. It is one of the ways in which a water body (lake, rivers, and seas) transforms from a state where nutrients are scarce (oligotrophic), through a slightly richer phase (mesotrophic) to an enriched state (eutrophic). Human activities often enhance the rate of change due to activities such as farming, forestry, road-building, industry and waste treatment that cause nutrients to enter watercourses. This nutrient enrichment often results in a population explosion of algae and other aquatic plants

Eutrophication BOD and Eutrophication - rapid succession in a body of water because of an increase in biological productivity. (Oligotrophic lakes and rivers have clear water and low biological productivity)

In shallow lakes and where plant production is high, deoxygenation of the sediment and water occur frequently too (black sediment, Photo 3)
