Vanoise National Park

Dams and reservoirs in Vanoise National Park

Explore the hydroelectric infrastructure of Vanoise National Park, featuring the prominent twin reservoirs of Plan d'Amont and Plan d'Aval in the Aussois mountains. This collection highlights the complex network of water intakes (prises d'eau) and dams that capture glacial meltwater and stream runoff. These engineering sites, connected by miles of underground galleries, offer unique vantage points over the park's rugged alpine terrain and glacial valleys while powering the Maurienne and Tarentaise regions.

Dams and Reservoirs — Map

A

Le Plan d'Amont

High-altitude reservoir at 2,078 meters, part of the Aussois hydroelectric complex. Its waters are used to generate power for the Maurienne valley.

B

Le Plan d'Aval

Located at 1,948 meters, this reservoir sits just below Plan d'Amont and serves as a primary storage basin for the Aussois power plant.

C

Prise d'Eau de la Calabourdane

Water intake structure collecting flow from the Calabourdane stream to supply the regional hydroelectric network.

D

Prise d'Eau du Charvet

Technical installation designed to capture mountain runoff from the Charvet sector for power generation.

E

Barrage de la Raie

Small dam located in the Tarentaise valley, managing water flow for local hydraulic systems.

F

Barrage de l'Ecot

High-altitude dam situated near the historic stone hamlet of L'Ecot, capturing water from the upper Arc river.

G

Prise d'Eau du Nant

Stream intake facility collecting water from the Nant torrent for diversion into the power grid.

H

Prise d'Eau du Ponturin

Diversion structure on the Ponturin stream, which drains the Peisey-Nancroix valley.

I

Prise d'Eau du Pingon

Technical water capture point located in the high-altitude terrain of the Vanoise massif.

J

Prise d'Eau du Thibaud

Hydraulic installation capturing stream water for the park's interconnected hydroelectric energy grid.
