ABSTRACT
It has been shown that the disappearance of lakes is understood as a decrease in water resources and not
only as the shrinkage of their area. It is mainly a result of the process of infill of lake basins. The conclusion
is based on observational data collected for 25 lakes. In a period of over 50 years the area of lakes has
decreased by 5.6% (compared to IIF data), while volume has decreased by 9.9%.
