Map Viewing Service (WMS) of the dataset: Areas of competence of river unions in Charente.

Areas intersecting the Charente department where the competence of a river union is exercised with regard to the development of non-domanial watercourses.

Each polygon results from the intersection of the water catchment area concerned (the Loire-Bretagne and Adour-Garonne water agencies) and all the municipalities (BD Topo) that are members of the intercommunality competent for river development.
