The results of many-year studies of production destruction processes in the Mozhaisk Reservoir are used to examine their specific features in extremely dry years. It is shown that the processes of organic matter formation and destruction in the reservoir are more active when water level is low. Variations in the intensity of production-destruction processes in all phases of synoptic cycle are analyzed (during cooling, cold, heating, and warm). Changes in weather conditions are shown to be accompanied by phytocenosis restructuring. Fine-cell phytoplankton forms are shown to dominate in phytocenosis composition when water level in the reservoir is extremely low.
