Reports of the provisional (drinking water) safeguard zones.

This layer contains the discharge points of the existing discharge structures (stormwater overflow basins, stormwater overflows and pumping stations with overflow)

Delimitation of agglomerations

Watercourses with a significant risk of flooding

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 second river basin management plan is based on the list of substances of directive 2008/105/EC as well as its environmental quality standards. The assessment without the ubiquist substances permita to get a differentiated picture of the actual situation.

Phytoplancon is one of the 4 biological quality elements (BQE) for the assessment of the ecological status of the natural water bodies. The evaluation of this BQE is only relevant for the large rivers where the quantity of phytoplancton is significant and can be evaluated. The natural water bodies of typology VI present significant phytoplancton concentrations to allow an assessment. Some of the heavy modified waterbodies (HMWB) present significant phytoplancton concentrations too, these are the HMWB Sûre (WB III-2.2.1) and the HMWB Our (WB V-1.2). The annual frequency for phytoplancton monitoring is 6 samples between April and October.
