Franco-Swiss cooperation for the water of Lake Geneva

The International Commission for the Protection of the Waters of Lake Geneva (CIPEL),
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 those of the cantons of Vaud, Valais and Geneva.

Its perimeter, covering an area of more than 10,000 km2, covers the Lake Geneva watershed and, more globally, the Rhone upstream of the French-Swiss border.
