During the month of February, there were 406 stations with exceedances, a hundred more than the previous month. Most of them are located in Spain (106 stations). In Poland there are 85 stations with exceedances and in Italy there are 62 stations. 

In addition, there are 50 stations in Germany, 19 in Sweden, 15 in Belgium and 13 in Ukraine. The following countries have recorded 10 stations or less with exceedances this month (from highest to lowest): Hungary, Slovakia, Luxembourg, Bosnia and Herzegovina, Norway, Croatia, Slovenia, Czech Republic, Romania, Iceland, Serbia, Moldova, Austria, France, Netherlands, Ireland, Estonia and Lithuania.

As for the river basins, the main river basin with values above the thresholds this month is the Oder River, with 48 stations in two different countries with Poland standing out. The Po River, in Italy, is the next river basin with the highest number of stations (46), followed by the Vistula River basin with 43 stations showing exceedances in Poland and Ukraine. A total of 72 different river basins have exceedances in February.

In terms of stations that recorded values of mean discharge above the 90% quantile, 289 exceeded this threshold this month. In February, Spain was the country with the most stations in this situation: 64. Poland, with 52 stations, and Norway with 28, are the countries with the next highest number of stations in this situation. The Spanish stations are distributed in eight different river basins, highlighting the Ebro River with 25 stations exceeding this quantile. In Poland there are two basins affected (Oder and Vistula) while in Norway the Glomma River is the most affected. In Austria, 24 stations have values above this quantile. In Ukraine 23 stations exceed this cliff. Other stations exceed the 90% quantile value in up to 23 countries.

By river basin, the Danube River stands out with 63 stations above the 90% quantile. The Vistula River basin is the second with the highest number of stations over this cliff, showing 34 stations in this situation and followed by the Ebro river basin with 25. A total of 60 different river basins have at less one station with mean values over the 90% quantile in February.

Finally, and according to the number of stations recording mean values below the 10% quantile, in February there were 21 stations with average values below this cliff at seven different countries.

This month, Spain is again the country with most of the stations (14), followed by Romania with 2 stations. The other affected countries show one station in this situation: Italy, Austria, Bulgaria, Iceland and Poland

In terms of river basin, this month the Danube River and the Llobregat River are the ones with the highest number of cases, with 4 stations each with an average discharge below the 10% quantile. The Ebro River shows three stations, the same number that the Jucar River. In total, as many as 11 different basins have values below this limit in Europe.
