| eutrophication |
The introduction of an excessive amount of nutrients (notably nitrogen and phosphorus) into an aquatic ecosystem causes a proliferation of algae. Decomposing algae consumes a great deal of oxygen, endangering fish and other aquatic animals. Eutrophication occurs most often in ecosystems where water is renewed very slowly, such as deep lakes.

| eutrophic |
Eutrophic conditions occur when the concentration of nutrients in rivers, estuaries, and other bodies of water increases and results in anaerobic (lack of oxygen) conditions in the water column. The increase of nutrients stimulates algae "blooms" as the algae decays and dies, the availability of dissolved oxygen is reduced resulting in high BOD; as a result, creatures living in the water accustomed to aerobic conditions perish.

| eutrophication |
the over-enrichment of a water body with nutrients causing increased phytoplankton growth. Secchi disk depth can be a good measure of eutrophication, especially in lakes. Secchi disk depths for eutrophic lakes ranges from 1.5 - 3 meters, while depths for oligotrophic (nutrient-poor) waters are greater than 6 meters. Ultraoligotrophic waters can have Secchi disk depths greater than 12 meters!

| eutrophic |
Having waters rich in mineral and organic nutrients that promote a proliferation of plant life, especially algae, which reduces the dissolved oxygen content and often causes the extinction of other organisms. Used of a lake or pond.
