The name Arc would come from “ar” which would mean “valley in the form of a plain”. This tributary of the Isère has its source at 2770 m at the foot of the former Trois Becs glacier and at Lac des
Lower springs, close to the Franco-Italian border.
With a length of 128 km, and thanks to steep slopes, the Arc has been exploited by many industrialists, in particular for hydroelectricity.
