V zadnjih desetletjih v Sloveniji opažamo povečanje števila tako ekstremnih poplavnih kot tudi ekstremnih sušnih dogodkov. To kaže na potrebo po kompleksni analizi trendov v serijah podatkov o pretokih. V raziskavi smo s pomočjo testa Mann Kendall analizirali statistične trende sezonskih in letnih povprečnih, največjih, ekstremnih in nizkih vrednosti pretokov. Rezultati kažejo časovno in prostorsko spremenljivost trendov pretokov. V splošnem smo zaznali trend zmanjševanja količin vode v rekah. Rezultati nekaterih vodomernih postaj pa kažejo na statistično značilno naraščajoče trende, zlasti za največje in ekstremne pretoke. Dodatne analize kažejo, da so trendi pretokov odvisni od lokacije vodomerne postaje.
