an intergovernmental Franco-Swiss body, has been contributing since 1963 to the coordination of water policy on the scale of the Lake Geneva basin, i.e. between France and Switzerland, and more particularly on the territories of the departments of Ain and Haute-Savoie as well as the cantons of Vaud, Valais and Geneva.
