From 1894 to 1995, the water level of the lake was regulated "by hand" using movable wooden gates attached to the Pont de la Machine. The dam was inaugurated in 1995, with 3 objectives: control the water levels of Lake Geneva; regulate the flow of the Rhone; produce electricity. 



Le barrage est équipé d'une passe à poisson permettant chaque année à 4'000 poissons de remonter le fleuve, ainsi que d'une rampe facilitant le passage des castors. Depuis 2002, l'ouvrage a reçu la certification naturemade star, un label qui garantit la provenance de l’énergie et la qualité de sa production selon les critères les plus exigeants d’Europe. Ceci lui permet aujourd’hui d’alimenter le produit Electricité Vitale Vert.
