Bairon reservoir




History of the installation :

Work on the Ardennes canal, which links the Meuse canal with the Aisne lateral canal, started in 1821. Twelve years later, operations started.

In addition to the two water outtakes from the Bar, the Bairon reservoir supplies the Ardennes canal summit reach by gravity, at kilometre point 23.500.

This reservoir dam was built on the Bairon stream to increase to 4,500,000 m³ the 600,000 m³ of water already stored in an existing reservoir. This installation comprises a main downstream dyke and an intermediate dyke between the two reservoirs (the upstream one being the smallest).
