Abstract. Active formation of abrasion-accumulative shallows in very close to the coastline of the Volgograd reservoir occurs as a result of coasts abrasion and alongshore sediments transport. The overgrowth of reservoirs by higher aquatic vegetation, in addition to the level regime, is determined by the process of coastal abrasion and the formation of coastal shallows. The purpose of this research is detection of phytoindicators of the shallows development process. Data of field researches of the Volgograd reservoir by 2010–2020, archival data 1962–2010, literary sources, satellite images are materials of this paper. Field and analytical research methods were applied in this work. The growth of coastal shallows continues now, because the process of abrasion continues dynamically. Active development of shallows from 1962-2010 with the attenuation of the process at the end of the period contributed to the formation of higher aquatic vegetation thickets in shallow waters and an increase in the degree of overgrowth from 0,9 % to 10,5 %. Water level fluctuation became the limiting factor of overgrowth of shallow waters in 2010–2018. We allocated 3 stages of abrasion-accumulative shallows development depending on the distribution of higher aquatic vegetation communities. These stages are early, mature and fading ones. Active bays separation begins when coastal shallow convers to the fading stage. Dynamic development of formations of submerged hydrophytes and helophytes in the bays entrance gates indicates to this stage. Phytoindicators of the process are submerged hydrophytes such as pierced-leaved pondweed, brilliant-leaved pondweed and combedleaved pondweed and helophytes such as common reed and narrow-leaved cattail

Key words: Volgograd reservoir, abrasion-accumulative shallows, overgrowth, phytoindication, development stages of coastal shallows, process of bays separation
