The article contains lists of 74 species (1252 specimens) of Coleopteran from 15 families: Carabidae – 13 species, Hydrophilidae – 12, Dytiscidae – 6, Elateridae – 6, Curculionidae – 4, Coccinellidae – 3, Heteroceridae – 2, Tenebrionidae – 2, Chrysomelidae – 2, Spercheidae, Scirtidae, Cantharidae, Bostrichidae, Anthicidae and Cerambycidae – in 1 species.

The present work is a continuation of the inventory of the coleopterofauna of the water-terrestrial ecotones of the nature monument «Rasskazan’ Lake» Balashov district of Saratov province, which began in 2017. The study concerned the spring fauna of the period of occurrence of the Khoper river in low water after floods and the beginning of the stagnation of the lake water level.
