According to the water framework directive WFD(DIR 2000/60/CE), important physico chemical parameters 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 30 December 2010 (règlement grand-ducal you 30 décembre 2010 concernant l 'évaluation of the dimension d' eau de surface).

The "good ecological potential" is the environmental quality objective defined by the water framework directive for artificial and heavily modified surface water bodies. The ecological potential is assessed in four classes ranging from 1 to 4 (good and higher, moderate, poor, bad). The classification of the ecological potential is based on the biological, physico-chemical and in some cases also the hydromorphological quality elements.

According to the WFD (Water framework directive) the assessment of the stauts of the surface water bodies is based on the evaluation of the monitoring results. According to Article 8 of the WFD, Member States must ensure the establishment of monitoring programs, inter alia, for surface waters. The monitoring of the surface water bodies is carried out at surveillance monitoring stations and operational measuring points. For surface waters, the WFD also foresees an investigative monitoring.

With regard to the implementation of the Water Framework Directive, specific types of watercourses have been designated for Luxembourg. As in the context of various works the German stream types (LAWA types) are used, these have also been assigned to the Luxembourgish surface water bodies.
