A comparative analysis of the maximum water levels formation of the rivers in the Belarusian Lakeland and the Belarusian Polesie for the period from 1946 to 2015 was carried out. Three periods were studied: 1946…1965 – the period before the mass reclamation, the peri-od of minimal anthropogenic impacts, can be conditionally accepted as a natural water regime;
1966…1987 – the period of mass reclamation; 1988…2015 – the period of modern climatic impacts. The methodological basis of the research was the scientific provisions on the stochastic nature of the variability of the river level regime and the comparative geographical method. It is established that for the rivers of the Belarusian Lakeland there is a steady tendency to decrease the maximum water levels at a rate of minus 31 cm / 10 years in general for the entire period under review, while there is a slight decrease for the rivers of the Belarusian Polesie.
