Data on the composition, content, and interannual dynamics of photosynthetic pigments in water of the Upper Volga reservoirs in the summers of 2005 and 2012–2016, continuing the series of long-term observations, are given. With an average content of chlorophyll (Chl a) from 13.1 ± 1.4 to 52.5 ± 2.7 μg/L in the Ivankovo Reservoir and from 7.6 ± 1.6 to 27.5 ± 2.5 μg/L in the Uglich Reservoir, an increase in Chl a is observed after the anomalously hot 2010. Interannual changes in Chl a in dependence on the water temperature, as well as the Wolf numbers and North Atlantic Oscillation index (NAO) that indirectly affect phytoplankton productivity, are analyzed. Chl a content in the Ivankovo Reservoir, which retains the eutrophic status, does not go beyond the long-term fluctuations, while an increase in the absolute and relative amounts of Chl a in the Uglich Reservoir indicate an increased role of blue-green algae and transition of the reservoir to the eutrophic category.
