Abstract: Reassessing the hydrological characteristics with regard to drought is very important in the context of a changing climate.In this paper, we evaluate the drought in terms of changes in hydrological characteristics for the 20-year period 2001-2020.The evaluation of changes is based on a comparison of data for this period with the currently valid reference period 1961-2000 in 13 selected water-gauging stations.In the analysis of the occurrence of subnormal mean annual discharges (Qr <90% Qa,1961-2000), in most of the evaluated stations, the percentage incidence of such years is higher in the period 2001-2020 than in the reference period.The distribution of runoff throughout the year in the period 2001-2020 in comparison with the reference period in most stations confirms the changes identified in the previous evaluation of the period 2001-2015, i.e. the transfer of part of the usual increased spring runoff to previous, winter months.An exception was water-gauging stations on streams in the mountainous areas of northern Slovakia, where changes are reflected to a lesser extent.
