SAGE boundary

Geographical boundary for the scope of a sub-basin management plan (SAGE). This scope is a sub-basin, a group of sub-basins corresponding to a consistent hydrographic unit or aquifer system. If the boundary is defined by the river basin management plan (SDAGE), it can be delimited by prefectural order. Otherwise, the planned boundary is transmitted for review to the regional councils, departemental councils and municipalities whose territories are entirely or partly located within the boundary as well as local public basin authorities, basin committee and the basin coordinator prefect involved. It is then the prefect's decision.
