The chemical status of the surface water bodies is assessed as being good or failing to achieve good chemical status. The assessment of the chemical status for the third river basin management plan is based on the list of substances of directive 2008/105/EC and the environmental quality standards established by the new directive 2013/39/EC.

The ecological status of the natural surface water bodies is assessed in 5 classes going from 1 to 5 (high, good, moderate, poor, bad). The classification of the ecological status is based on the biological quality elements, physico-chemical quality elements and in some cases also the hydromorphological quality elements.

The chemical status of the surface water bodies is assessed as being good or failing to achieve good chemical status. The assessment of the chemical status for the third river basin management plan is based on the list of substances of directive 2008/105/EC and the environmental quality standards established by the new directive 2013/39/EC. The assessment without the ubiquist substances permits to get a differentiated picture of the actual situation.

Phytoplancon is one of the 4 biological quality elements (BQE) used for the assessment of the ecological status of the surface water bodies. The assessment is made in 5 classes : high (blue) - good (green) - moderate (yellow) - poor (orange) - bad (red). The evaluation of this BQE is only relevant for the large rivers where the quantity of phytoplancton is significant and can be evaluated. Therefore phytoplancton is assessed in natural water bodies of type VI an in heavy modified waterbodies (HMWB) presenting a lake character, as the HMWB Sûre (WB III-2.2.1) and the HMWB Our (WB V-1.2). The frequency for phytoplancton monitoring is annually with 6 samples between April and October.

River protection against the impact of adjacent land use (agricultural runoff such as nutrients and pesticides, fine sediments, cattle trampling, erosion, etc.) through the establishment of fenced riparian buffer stripes, free from any use, where a typical riparian vegetation will grow and provide shade for the river.

According to the water framework directive WFD (DIR 2000/60/CE), important physico chemical parameters and river basin specific pollutants are measured in the surface water bodies for the assessment of the ecological status. The modalities for this monitoring are stated in the grand ducal Regulation of 15 January 2016 (règlement grand-ducal du 15 janvier 2016 concernant l'évaluation of the dimension d'eau de surface).

Macrophytes and phytobenthos (diatoms) are two sub-elements of the biological quality element (BQE) of the aquatic flora used for the assessment of the ecological status/potential. The assessment of the aquatic flora is made in 5 classes : high (blue) - good (green) - moderate (yellow) - poor (orange) - bad (red). The aquatic flora ist assessed following the sub-element the less good (worst-case).

Macrophytes are a sub-element of the biological quality element (BQE) of the aquatic flora used for the assessment of the ecological status/potential. The assessment is made in 5 classes : high (blue) - good (green) - moderate (yellow) - poor (orange) - bad (red). Macrophytes are particularly sensitive to organic pollution, trophy and hydromorphology.
