Based on long-term observations, we examine the seasonal and interannual dynamics of the phytoplankton and chemical composition of the water in Lake Zavernyaikha located in the delta of the Selenga river. The study revealed an intense development of five kinds of phytoplankton under the ice, dominated by dynophyte algae: the Baikalian endemics G. baicalense and P. baicalense. The main factors of massive algae development under the ice are: the favorable gaseous regime and relationship of biogenic elements, high content of volatile organic substances (VOS), isolatedness of the water body, and high rate of dynophyte algae division.

Keywords: phytoplankton, biogenic elements, VOS, gaseous regime.
