Chavière water abstraction point

Four water abstraction points capture the waters of the Doron de Pralognan and its smaller tributaries - the Chavière, Glière, Isertan and Vuzelle - before they are transported to the power plant. This is the Chavière water point. 8m3/s transit through an underground gallery around 13km long with a diameter of more than 2 metres and join a 1,700-metre penstock with a change in gradient of 765 metres.
