During the month of July, there were 33 stations with exceedances. the majority of these stations are in Spain (10), in Norway (nine), and Italy (eight). In  Spain, where almost all exceedances are related to the water level threshold, the stations are mainly located in north-east of the Iberian Peninsula. The Minho river basin is the only instance in Spain with exceedance related with discharge. In Norway, all exceedances are related to the discharge threshold, and stations are distributed across eight different basins in the west of the country. On the other hand, in Italy all exceedances are centered on the Po river and are related to the water level threshold. 

Additionally, there are two stations with exceedances in Poland, and the remainder of countries  show exceedances of only one station each for the month.

In terms of river basins, the main basin showing values above the threshold is the aforementioned Po basin, Italy. The Llobregat river basin in Spain is another basin which can be highlighted in this way, with five exceedances. 

Regarding the stations that recorded values above the 90% quantile, 37 exceeded this threshold in July. Once again this month, Spain is the country with the highest number of stations (18), with the Júcar river being the most numerous with seven. In the south of the Iberian Peninsula the Guadalhorce, the Guadalquivir and the Guadiaro are the basins with stations recording values above the 90% quantile, and in the eastern area the Jucar stands out. In Norway there are eight stations exceed this quantile, four in Italy and three in Ukraine.

Other stations exceeded the 90% quantile value in Autria, Finland, Slovenia and England.

By basins, in addition to the aforementioned Jucar, the Dnieper river stands out with three stations, the same as the Guadalquivir river. The sum of 24 different river basins shows exceedance over the 90% quantile.

Finally, and according to the number of stations recording mean values below the 10% quantile, the trend is maintained and we find an increase of more than 60%. In the month of July, there are 364 stations with average values below this cliff, which impacts 23 different countries.

Also this month, Germany is the country with the most stations (75), followed by France (45) stations. Different countries have 24 stations below this threshold: Spain, Poland and Hungary, and more than 20 can be found in Austria, Croatia, Ukraine, and Switzerland.

In terms of basins, it is again the Danube river the one with the highest number of stations, with nearly three times the value of the previous month, reaching 143 station with average discharge below the 10% quantile. The Rhine basin has 69 stations in the same situation. In total, as many as 42 different basins have values below this limit.
