Definitions:

Lakes

Inland bodies of standing freshwater or, in some cases, saline water, usually larger than ponds and contained by land.

Eutrophic

A condition of water bodies, such as lakes and rivers, characterized by an abundant accumulation of nutrients that promote a proliferation of algae.

Mesotrophic

Lakes and water bodies characterized by an intermediate level of productivity, richer than oligotrophic waters but not as nutrient-rich as eutrophic waters.

Oligotrophic

refers to bodies of water, such as lakes, that are low in nutrients and productivity but often high in clarity.
