We present the results of long-term studies of the nutrient concentrations in the Barguzin River and Barguzin Bay. The bay has specifics in the spatial distribution as well as seasonal and interannual dynamics of the nutrient concentrations. In the interannual aspect, the concentrations of mineral forms of nutrients decreased in the bay. Based on the total phosphorus concentration, the water in Barguzin Bay is classified as slightly polluted.
