Trophic state index
WebOther Trophic State Index Approaches . Carlson (1977) proposed a trophic state index system which is based on total phosphorus, chlorophyll, and Secchi depth. Except for the inclusion of total phosphorus as a parameter, this approach was an improvement over previously-discussed multiparameter approaches that have been used in the past.

The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to … See more Carlson's index was proposed by Robert Carlson in his 1977 seminal paper, "A trophic state index for lakes". It is one of the more commonly used trophic indices and is the trophic index used by the United States Environmental Protection Agency See more Both natural and anthropogenic factors can influence a lake or other water body's trophic index. A water body situated in a nutrient-rich region with high net primary productivity may be naturally eutrophic. Nutrients carried into water bodies from non-point sources such … See more • Biomass (ecology) • Eutrophication • Nonpoint source pollution • Secchi disk See more A lake is usually classified as being in one of three possible classes: oligotrophic, mesotrophic or eutrophic.
