The results of the studies on macrozoobenthos in the Upper Volga reservoirs in 2009-2015 are presented. New habitats of alien species Lithoglyphus naticoides, Quistadrilus multisetosus, and Archaeobdella esmonti have been found. The dynamics of distribution and abundance of these invaders in the Volga reservoirs has been monitored. The mollusk of the genus Corbicula has been found in the Gorky Reservoir for the first time.
