The lake’s trophic state can well represent human disturbances on these ecosystems. The present study was conducted seasonally to investigate the trophy status of Bostan Dam Lake (Golestan Province) from spring 2019 to summer 2020 in five study stations. A number of physicochemical parameters were determined such as pH, electrical conductivity, temperature, dissolved oxygen concentration, Secchi disk depth, salinity, dissolved solids, total hardness and turbidity. While nitrate, phosphate, total nitrogen, total phosphorus, ammonia, total alkalinity and chlorophyll evaluated using standard method. Carlson's index, the amount of nutrition in different parts of the lake estimated based on total phosphuros, chlorophyll and transparency. The result of Carlson's index showed different values between 52.44 to 60.46 and eutrophic condition in lake. The present research can provide a decision support system in the future to achieve optimal monitoring and exploitation and water quality management of the reservoir behind the Bostan Dam.
