The study presents preliminary results of investigating the coastal morphosystem of the Taipalovskii Bay in Lake Ladoga, aimed at reconstructing water-level fluctuations. The comprehensive research conducted includes: geomorphological profiling, peat coring, OSL dating of shoreline deposits, radiocarbon dating of peat deposits, and diatom analysis of dated samples. It has been established that the accumulative shore of the bay was formed throughout the Holocene due to multiple transgressive-regressive cycles. It is suggested that the large beach bar, previously believed to have formed during the Ladoga transgression, already existed in the mid-Holocene. The maximum level of the transgression itself is estimated to be around 14-15 meters in height.
