Abstract: The features of the formation of aquatic plant communities and their spatial distribution at the outlet sections of the waterways of the Volga delta are shown. It can be noted that the coastal-aquatic vegetation of kultuk zone and island zone of the avandelta of the studied areas is similar in species composition, but differs in the structure of communities, projective cover and the abundance of individual species. In the riverbed area where the flow is strong enough with silty-sandy deposits the mass development of the reophilic communities of Potamogeton lucens is traced. With the weakening of the flow on the silty sediments forbs association with (Butomus umbellatus, Sparganium ramosum, Nymphoides peltata, Trapa natans, Ceratophyllum demersum and other plants observed. In the kultuk zone, mosaic poly dominant communities (Phragmites, Sparganium, Potamogeton spp., Vallisneria and other hydrophytes) are noted. The submerged vegetation is represented by the communities of Potamogeton perfoliatus, Potamogeton pectinatus, Vallisneria spiralis, Ceratophyllum demersum with a projective coverage up to 100%. Surface plants disappear from the composition of plant communities and submerged hydrophytes only remain. Potamogeton pectinatus, Vallisneria spiralis and Ceratophyllum demersum dominate and subdominate.
