Abstract
The results of a comparative analysis of the characteristic water levels in the Angrapa River (Berestovo gauging station, Kaliningrad region) in the middle of the 20th and at the beginning of the 21st century are presented. A number of average annual discharges of the Angrapa river (Berestovo gauging station) have been restored for analogue rivers. It has been established that the average long-term levels of the Angrapa river have decreased over the period under review. At the beginning of the 20th century, intra-annual changes in water levels with a spring flood peak, summer-autumn low water and rises during rain floods on the Angrape River were noted in less than half of the cases. In the 21st century, such a change occurs only in some years, in other years there are several rises in the water level, from December to March-April. The highest level in the Angrapa river (Berestovo gauging station) was recorded during a rain flood. The hydrological regime of a water body has a significant impact on the conditions for the existence of ecosystems, the level regime of a river significantly affects the floodplain ecosystem. The data obtained can be used in the development of environmental measures.
