This article is the result of a research conducted in the Zubov State Oceanological Institute during 2014-2019. The research was aimed at studying the coastal dynamics, as well as evaluating the quality of waters of the Onega Lake and the impact of natural and anthropogenic factors on it. Those factors were considered and characterized, the most important of them, in addition to human activity, are the solid flow of rivers and the flow from abrasion processes. Seven types of coasts were identified for the Onega Lake, each of which has its own characteristics of dynamic processes and the impact of natural and anthropogenic factors on water quality. The dynamics of the coasts were analyzed both in the course of field studies and using mathematical modeling methods, which allowed revealing the main tendencies in the dynamics of the coasts. Pollutants entering the Lake and affecting the quality of water are also divided by origin into natural, anthropogenic and mixed genesis pollutants. Special attention is paid to the natural sources of pollution, since they are considered in the available literature to the least extent. Natural origin pollutants include, in particular, the majority of heavy metals, which concentrations for various sites were determined during the research.
