Extent: E+W+S+N.I.

(i) For surface water categories, the ecological status classification for the body of water shall be represented by the lower of the values for the biological and physico-chemical monitoring results for the relevant quality elements classified in accordance with the first column of the table set out below. Member States shall provide a map for each river basin district illustrating the classification of the ecological status foreach body of water, colour-coded in accordance with the second column of the table set out below to reflect the ecological status classification of the body of water:
Ecological status classification

Green
Moderate
Yellow
Poor
Orange
Bad
Red
(ii) For heavily modified and artificial water bodies, the ecological potential classification for the body of water shall be represented by the lower of the values for the biological and physico-chemical monitoring results for the relevant quality elements classified in accordance with the first column of the table set out below. Member States shall provide a map for each river basin district illustrating the classification of the ecological potential for each body of water, colour-coded, in respect of artificial water bodies in accordance with the second column of the table set out below, and in respect of heavily modified water bodies in accordance with the third column of that table:
Ecological potential classification
Colour code
Artificial Water Bodies
Heavily Modified
Good and above
Equal green and light grey stripes
Equal green and dark grey stripes
Moderate
Equal yellow and light grey stripes
Equal yellow and dark grey stripes
Poor
Equal orange and light grey stripes
Equal orange and dark grey stripes
Bad
Equal red and light grey stripes

(iii) Member States shall also indicate, by a black dot on the map, those bodies of water where failure to achieve good status or good ecological potential is due to non-compliance with one or more environmental quality standards which have been established for that body of water in respect of specific synthetic and non-synthetic pollutants (in accordance with the compliance regime established by the Member State).
