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.

WebThe trophic state index (TSI) is a convenient way to quantify this relationship. TSI is calculated independently from Secchi disk depth, chlorophyll a, and total phosphorus concentration. It should be taken into account that TSI was developed for use with lakes that have few rooted aquatic plants and little nonalgal turbidity.
