The research was carried out in the “El Toro” and “Los Angeles” lagoons, located in the Santiago Chuco province, La Libertad region. Sampling was carried out from May to August 2023 in 2 stations. The objective of the study was to evaluate the trophic state of the “El Toro” and “Los Angeles” lagoons. Sampling was carried out in situ. To obtain transparency, the Secchi disk was used; To obtain Total Phosphorus, the Ascorbic Acid SM 4500-E method was applied and for chlorophyll “a” the Welschmeyer Fluorometry method was applied. The index proposed by the Organization for Economic Cooperation and Development (OECD) and the Carlson Index were used to classify the trophic state. The transparency results ranged from 3.7 to 6 m in “El Toro” lagoon and 3.2 to 4 m in “Los Angeles” lagoon; Total phosphorus fluctuated between 22 to 41 μg/L in “El Toro” lagoon and 30 to 44 μg/L in “Los Angeles” lagoon; Chlorophyll “a” fluctuated between 31.16 to 36.12 μg/L in “El Toro” lagoon and 36.13 to 44.36 μg/L in “Los Angeles” lagoon. According to the OECD, the trophic state for “El Toro” lagoon in transparency is mesotrophic; for total phosphorus it is mesotrophic and eutrophic; for chlorophyll “a” it is hypertrophic. In the “Los Angeles” lagoon, for transparency, it is mesotrophic; for total phosphorus it is mesotrophic and eutrophic; for chlorophyll “a” it is hypertrophic. While Carlson, the trophic state for the “El Toro” lagoon for transparency is mesotrophic; for total phosphorus it is eutrophic; for chlorophyll “a” it is eutrophic. In the “Los Angeles” lagoon, for transparency, it is mesotrophic; for total phosphorus it is eutrophic; for chlorophyll “a” it is eutrophic.
