Observations

For the year 2015, data are provided for the first cycle basin hydrological plans (2009-2015). And for the years 2017 for the second cycle (2015-2021). The hydrological plans have a comprehensive review of the data on a six-year basis, although partial reviews are carried out annually. The concept "good quality" is associated with "good state" of the masses according to Directive 2000/60/EEC or Water Framework Directive.
