After a long struggle over 30 years, the New Poutès dam on the Upper Allier River, tributary of the Loire River, is officially inaugurated on 24 October 2022.
The dam, which was partialy removed from 20 m to 7 m, is now equipped with a fish lift and two huge gates. They are fully opened every year for 3 months and during floods and ensure good passage, especially for Europe’s last wild salmon. The downstream migration is also guaranteed by the low dam height of 6 m and the reduction of the length of the dam from 3.5 km to about 0.5 km. The project allow also the fully restoration of 20 km of the Allier River.
The “Nouveau Poutès” project has been co-constructed over the last 10 years by EDF, NGOs including ERN-SOS Loire Vivante, the municipalities and other stakeholders and can be described as the result of collective intelligence.
