Hydrological drought is a recurring extreme hydrological phenomenon that negatively affects surface water levels and groundwater levels in basin. The monitored territory, i.e. the vicinity of Vychodoslovenská lowland ranks among the most vulnerable to the phenomenon of hydrological drought. This paper deals with the one-dimensional frequency analysis of historical severe drought events in groundwater in four sub-catchments namely: Dunajec and Poprad, Bodva, Bodrog, and Hornád using Standardized Streamflow Index (SSI) computed in 24-months’ time scales for identification of this phenomenon for the reference period from 1972 to 2019. The analysis was done at seven water meter stations situated in the Eastern part of Slovakia. Then, a severe hydrological drought event was identified if the index value was less than −1.5. At the beginning of 2009, the most serious and longest groundwater drought event was recorded in the Hornad sub-basin at Kysak station, which lasted 28 months. The results showed that the year 1994 was a significant year in which severe hydrological drought was recorded at five water meter stations. Predicting the natural phenomenon with the help of inter-arrival time helps in prevention of drought, as well as in introduction of regional preventive measures ensuring the minimization of negative impacts on people and their activities and the environment. The shortest drought return time is recorded in Kysak namely 2.5 years, and the longest drought return time 11.9 year is recorded in Humenne.
