A fish pass between two sections of the Marne, downstream and upstream of the Meaux dam (Seine-et-Marne), allows fish species to pass. Nineteen triangular walls with an “indentation” and alternating from one bank to the other over a length of 250 m.
A bed lined with rocks facilitating the rise of the river and a total bill of 6 million euros. “It’s one of the largest fish passages in Île-de-France,” explains Frédéric Da Silva, responsible for the work of the dam.
