GD. P.12First Dixence dam and outline of the future Grande Dixence schemeDix Valley soon became accepted as the site with thegreatest potential for development. This high mountainvalley had all the geological and topographical conditionsthat made it ideal for conversion to a giantreservoir. No built-up area would be affected, the onlyagricultural land was high altitude pasture and, aboveall, the predicted storage capacity was enormous: 400million m 3 .These two achievements engaged more than 3000men in a struggle that lasted through to the beginningof the 1960s. A bold avant-garde project thattoday contributes to the well-being of the whole community.Geologists, hydrologists, surveyors and engineers tackledthe solving of two major problems. First, how toenlarge the existing lake with the Dixence complex builtsome 15 years before. Second, how to create collectingworks capable of gathering water from the neighbouringMatter, Ferpècle and Arolla valleys.
