Dams and Reservoirs
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.
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.
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.
Prise d'Eau de la Calabourdane
Water intake structure collecting flow from the Calabourdane stream to supply the regional hydroelectric network.
Prise d'Eau du Charvet
Technical installation designed to capture mountain runoff from the Charvet sector for power generation.
Barrage de la Raie
Small dam located in the Tarentaise valley, managing water flow for local hydraulic systems.
Barrage de l'Ecot
High-altitude dam situated near the historic stone hamlet of L'Ecot, capturing water from the upper Arc river.
Prise d'Eau du Nant
Stream intake facility collecting water from the Nant torrent for diversion into the power grid.
Prise d'Eau du Ponturin
Diversion structure on the Ponturin stream, which drains the Peisey-Nancroix valley.
Prise d'Eau du Pingon
Technical water capture point located in the high-altitude terrain of the Vanoise massif.
Prise d'Eau du Thibaud
Hydraulic installation capturing stream water for the park's interconnected hydroelectric energy grid.
Prise d'Eau de Miribel
Alpine water intake located in the Miribel sector of the national park.
Prise d'Eau d'Entre-Deux-Eaux
Water collection point located at the confluence of the Torrent de la Rocheure and the Leisse.
Prise d'Eau du Grand Pyx
Small-scale hydraulic structure capturing alpine runoff for regional water management.
Prise d'Eau du Povaret
Water intake facility located near the Orgère valley entrance.
Prise d'Eau du Saint-Bernard
Technical diversion point for mountain streams in the southern Vanoise region.
Prise d'eau
Standard water intake structure used for hydroelectric diversion.
Prise d'eau du Nant Putors
Capture point for the Nant Putors stream, contributing to the local hydroelectric management system.
