Subject. This article discusses the annual maximum levels of the Amur River in the area of Komsomolsk-on-Amur during 2002–2025. Objectives. The study aims to analyze the annual maxima of the Amur River gauge in comparison with the dam level, and develop a forecast of the Amur's water levels until 2030 to prevent the consequences of catastrophic floods. Methods. For the study, we used the methods of exploratory, regression, and variance analyses. Results. The article identifies periods of decrease/increase in the water level of the Amur River over 130 years and develops models for analyzing the levels of the Amur River in Komsomolsk-on-Amur for the purposes of warning and protecting the area from catastrophic floods. Conclusions. To reduce damage from catastrophic floods, it is necessary to construct/reconstruct protective hydraulic structures taking into account the maximum annual levels of the Amur River.
