Le Noeud Hydraulique de Bazoin
Return to find more about the Marais Poitevin
© Copyright Vendee-Guide.co.uk 2009
The 3 departments of Deux Sevres, Charente-Maritime and the Vendee meet on the Marais Poitevin near the borders of 3 communes: Maille, Damvix and La Ronde and here there is a group of engineering works that constitute a major site in determining the hydaulic management of the wetlands of the Marais Poitevin.
From 1855 to 1960 the site has seen successive changes to modernize these impressive mechanisms. The Deux Sevres dam was built first, such installations maintain constant water levels in the marshes of the Marais Poitevin, Then the lock gate system was added to allow shipping to use these major waterways.
Today modern techniques have replaced man in operating the works. The dam and the release of water are controlled by radio systems and electronic probes.
The dams and lock gate systems and the meeting of the waterways makes this a most picturesque place and one that most visiters to the area never get to see.
