This work discusses the spatial and temporal dynamics of nutrients in the pelagic zone of Lake Baikal to assess the changes in their concentrations and distribution in recent years. The study has revealed that at the end of the summer, phytoplankton almost completely consumes phosphates in the upper layers of water. There is a slight trend towards an increase in the weighted average concentration of nitrates in the water column of the pelagic zone of Lake Baikal.
