For October, the highest concentration of stations that exceeded their lowest threshold level was in the Po river basin in northern Italy, Rhine river basin in Switzerland and southern Sweden. In the rest of Europe, exceedances occurred in isolated stations in southern Norway, Danube river basin in Hungary, the Oder river basin in western Poland, Elbe river basin in western Germany, the Hiyon river basin in Israel and Guadalhorce river basin in southern Spain.

Stations that registered discharge values above the 90% quantile are mostly located in Great Britain and Ireland. In the rest of Europe, only isolated stations fulfil this condition: Danube river basin (Austria, Germany and Romania), Guadalquivir river basin in southern Spain, Loire river basin in France, Rhine river basin in Germany and France, Lotan river basin in Sweden and Glomma river basin in Norway.

Stations registering values below the 10% quantile were mainly in Poland (Oder and Vistula river basins), in eastern Germany (Oder river basin) and Danube river basin (southern Austria, Serbia, Romania, Germany, Slovakia, south-western Ukraine). A lower concentration of stations is found in Dniester river basins in Ukraine, Ebro river basin in Spain, south-eastern Sweden, Rhine and Elbe river basins in Germany, and Glomma and Beiarelva river basins in Norway. Finally, Maritsa river basin in Bulgaria and Loire river basin have only one station with this condition.
