Abstract
Data on the overgrowth level and biomass reserves in Volga reservoirs, collected in 2003–2009, are given. The long-term dynamics and the character of overgrowth of the Ivankovo, Uglich, Rybinsk, Gorki, Cheboksary, Kuibushev, Saratov, and Volgograd reservoirs are analyzed taking into account the published materials of the previous studies. The analyzed data include the specific features of variations in the diversity and production of vegetation cover in reservoirs in various natural–climatic zones in the Upper, Middle, and Lower Volga, as well as reservoirs with filling level either constant or abruptly varying (the Rybinsk and Kuibyshev) over years and within a year.
