Dams are of two types - storage dams and river dams. This account focuses on the Grand’Maison storage dam.
The Grand’Maison dam is in the upper Romanche valley, one of the birth-places of hydro-electric power.
This "high-head" dam is located between two pondages: Grand’Maison at an altitide of 1,700 m and Verney at 770 m.
