The Rhine River, focused in Germany and Luxembourg, is the next river basin with the highest number of stations (48), followed by the Oder River basin with 30 stations showing exceedances in Poland and Germany. A total of 56 different river basins have exceedances in January.

In terms of stations that recorded values of mean discharge above the 90% quantile, 312 exceeded this threshold this month. In January, Spain was the country with the most stations in this situation with 44. Poland (2039), and Germany (38) are the countries with the next highest number of stations in this situation. The Spanish stations are distributed in six different river basins, highlighting the Guadiana River with 33 stations exceeding this quantile. In Poland there are two basins affected (Oder and Vistula) while in Germany the Danube River and the Elbe river basins are the most affected. In Austria, 29 stations have values above this quantile. In Slovakia 21 stations exceed this cliff. Other stations exceed the 90% quantile value in up to 22 countries.

By river basin, the Danube River stands out with 118 stations above the 90% quantile. The Guadiana River basin is the second with the highest number of stations over this cliff, showing 33 stations in this situation and followed by the Oder river basin with 25. A total of 52 different river basins have at less one station with mean values over the 90% quantile in January.

Finally, and according to the number of stations recording mean values below the 10% quantile, in January there were 45 stations with average values below this cliff at nine different countries.

This month, Spain is the country with most of the stations (29), followed by Romania with five stations and Norway with 3 stations. Sweden and Italy show two stations each in this situation. Other countries show one station in this situation: Ukraine, Bulgaria, Iceland and Poland

In terms of river basin, this month the Guadalquivir River is again the one with the highest number of cases, with nine stations with an average discharge below the 10% quantile. The Ebro River with eight stations and the Danube River with four stations surpass the Jucar River basin, with three stations. In total, as many as 20 different basins have values below this limit in Europe.
