Dammen en stuwmeren in Parc National de la Vanoise

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.
