For the month of June, the highest concentration of stations that exceeded their lowest threshold level is located in central Europe, through the Danube, Oder, Vistula and Dniester basins (Poland, Czechia, Slovakia, Serbia, Romania, Bosnia and Herzegovina), in Italy (Po basin) and in the Scandinavian peninsula, mainly in Norway. There was a more dispersed distribution of stations with exceedances in the basins of the Rhine (southern Germany), Dnieper (Ukraine), Neman (Belarus) and Llobregat (northeast of Spain).
Stations that registered discharge values above the 90% quantile are located mainly in Norway, also extending in the north of Finland too. There is a high concentration of stations in the Danube basin, through Austria, Bulgaria, Czechia, Hungary, Romania, Serbia, Slovakia, and southwest Ukraine. In the Dnieper basin, specifically in the north and centre of Ukraine (Styr, Psel, and Vorskla rivers). There are only three stations in Germany that exceeded the 90% quantile on the Main and Lusatian Neisse rivers. Some scattered stations in the same condition can be found in England (Thames and Brit basins) and in Spain (Ebro, Ter and Guadalhorce basins).
Stations registering values below the 10% quantile are found in a greater number in Spain (Ebro and Douro basins and in the south of the country), in England (Thames basin), in Ireland, in central European basins such as the Rhine, Elbe, Oder and Vistula basins (in a lower concentration), and in Ukraine (Dnieper basin).
