Map Viewing Service (WMS) of the dataset: Competent bodies for river development in Charente.

Polygons intersecting the Charente department and bringing together the municipalities belonging to a syndicate of rivers competent for the development of non-domanial watercourses (referential: BD TOPO).

Municipalities transfer their powers to the establishment they create.
The transfer of powers to a lasting intercommunity may take the form of association cooperation (union and other groupings) or project cooperation (public institutions of inter-communal cooperation with own taxation — EPCI).
An EPCI may exercise only those powers which have been explicitly transferred to it either by law or by its member municipalities.

与夏朗德省（Charente）相交且涵盖隶属于负责非国有河道开发的河流管理联合体的所有市镇的多边形要素，参考数据源为BD TOPO。

市镇可将自身职权移交至其组建的公共机构。
向持久型跨社区共同体移交职权可采用协会合作（联盟及其他联合形式）或项目合作（拥有自主征税权的跨社区合作公共机构——EPCI）两种形式。
该类EPCI仅可行使由法律或其成员市镇明确移交的职权。
