For January, the highest number of stations that exceeded their lowest threshold level was in Norwegian basins, especially in the northern part of the country. A fewer number of stations with exceedances occurred in the Llobregat river basin in northeastern Spain, the Po river basin in Italy, basins in southern Sweden, Israel, as well as southwestern Danube river basin in Austria, Croatia and Bosnia and Herzegovina. In addition to the previous ones, we also find isolated stations exceeding the lowest threshold level in the rivers Oder and Vistula, in Poland, the Minho river in northwestern Spain, the Neretva river in Bosnia and Herzegovina, the Elbe river in Germany and the Neman river in Belarus.

Stations in the Elbe river basin in Germany and Czech Republic, in the Oder river basin (Germany and Poland), together with stations in the Dnieper basin (Ukraine), and the eastern Danube river basin in Serbia, Romania, Hungary and Ukraine, mainly registered values lower than the 10% quantile. We can also find stations showing values below 10% in the Rhine and Danube river basins in Germany. Besides those listed above, other isolated stations also showing values below the 10% quantile are located in the Danube (Czech Republic, Austria, Croatia and Bosnia and Herzegovina), Maritsa (Bulgary), Thames (England), Ebro (Spain), Vistual (Poland) and Kemijoki (Finland) river basins.

Contrastingly, stations that recorded discharge values above the 90% quantile are mostly in Norwegian, Sweden and Finnish river basins, as well as in several Spanish river basins, such as Guadalquivir, Douro, Ebro, Llobregat and Ter. To a minor extent, other stations also exceeding the 90% quantile occurred in western Danube (Austria and Germany), Thames , Welland and Trent river basins in England, as well as in the Swiss southern Rhine river basin. Values above the 90% quantile were also registered in isolated stations in Ukraine (Dnieper river) and Daugava, in Latvia.
