Dataset Direct Download Service (WFS): Mapping of rivers in Loire-Atlantique: Unique Water Cours (RUCE) for the Law on Water and Agricultural Regulations

This data is the reference for all planning actors and farmers (government instruction of 3 June 2015). It is the backstop of the State services for the investigation of cases under the Environmental Code and in particular for the Water Act. It is also the case for all agricultural regulations as well as the CAP aid cross-compliance rules (GAEC).
The layer is called N_COURS_EAU_LOIEAU_L_044.

The data relating to the mapping of rivers in the Loire-Atlantique subject to the law on water and agricultural regulations is a composite data formed in part and initially by the resumption of the river inventories conducted by the SAGEs “Estuaire de la Loire” and “Vilaine”. 75 % of the departmental territory is concerned.

Of the remaining 25 %, the mapping was carried out under the control of DDTM 44 in partnership with the actors in the territory: Chamber of Agriculture, AFB, SAGE-bearing structures, river unions, managers, communities.

Please note:
— The data includes the tertiary marshes networks which are subject to all regulations except headings 3110, 3120, 3130, 3140 and 3210 of the Water Act;
— inconsistencies may exist at the boundaries of departments.
