For March, the highest concentration of stations that surpassed the lowest discharge and/or stage threshold level was in southern Germany, along the Rhine and Danube river basins, and Belarus, along the Dnieper, Neman and Vistula river basins. A more dispersed distribution of stations with exceedances of the lowest threshold level occurred throughout the Danube river basins, the Po river basin in Italy, the Don river basin in the Ukraine, the Elbe river basin in the Czech Republic and Germany, the Jordan river basin in Israel, the Glomma river basin in Norway and the Minho river basin in north-western Spain.

Stations that registered discharge values above the 90% quantile are mostly located across Norway, Finland and Sweden, the western Danube river basin in Austria and Germany and as well as for several stations located throughout Ireland. This occurred less frequently for stations located along the Rhine river basin in Germany and Switzerland, the Dnieper river basin in the Ukraine, the Llobregat river basin in north-eastern Spain, the Vistula river basin in Belarus and the Danube river basin in Hungary and Slovakia.

Stations registering values below the 10% quantile for discharge are mainly located across the Danube river basin, in western Ukraine along the Dnieper, Dniester and southern Bug as well as in Spain along the Ebro, the Guadalquivir and the Llobregat river basins. This occurred less frequently in stations across Germany (the Elbe and Rhine river basins) and the Oder river basin in Poland.
