Fish passes in Rhinau and Marckolsheim: the work has really entered the active phase

terrassement passe à poissons Rhinau


Officially launched on 8 October 2021 by Mrs. Bérangère Abba, Secretary of State to the Minister of Ecological Transition, in charge of Biodiversity, the first shovels began to be dug in Rhinau and Marckolsheim this autumn 2022.

A great technical challenge awaits EDF. These fish passes will be the largest ever built in France and in Europe. The work will be carried out simultaneously on both sites, with commissioning scheduled for 2025 for Rhinau and 2026 for Marckolsheim. This is a great step forward and in line with the timetable announced at the last conference of ministers in Amsterdam in February 2020.

But a bigger challenge still awaits EDF on the Rhine: solving and developing the Vogelgrün dam, the last real obstacle before Basel. In this context the Salmon Comeback coalition will again ask the ICPR to set up an interdisciplinary working group dedicated to Vogelgrün in order to study additional alternative solutions to those studied in the past, which proved to be extremely complex and expensive.
