The genesis of the Sélune dam project was presented and also the restoration issues for a general interest and for the territory (general economy, fisheries, local population…). The sociological issues of dam removal were discussed along several talks and participation of association of the Friends of the Dams but also with a resident of the valley in favor to the project.
