In France, the schéma directeur d'aménagement et de gestion des eaux (SDAGE) is a document that aims to put into effect the principles of the law of 3 January 1992 on the level of the major hydrographic basins.
Its protection, exploitation and setting into a usable state while respecting natural balances, are of general interest.
The SDAGE serves as a general framework for the development and management of the water of each hydrographic unit, system or aquifer).
These are the schémas d'aménagement et de gestion des eaux (SAGE), that is water resource development and management outlines.
The aquifer and the hydro-electric and recreational uses of water in the Ain valley compose a clear example of a site where a coordinated approach could be productive.
