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. Where the assessment of whether bodies of surface water of the river and lake categories comply with good chemical status is carried out according to the criteria established by Royal Decree 817/2015 of 11 September, establishing the criteria for monitoring and evaluation of ecological status and environmental quality standards
