Bouzey reservoir




History of the installation :

At the end of the 1870 war, a ministerial decision of 1871 prescribed the study of a new waterway (Vosges canal) which, starting from the Marne au Rhin canal, would go through to the upper part of the Saône.

Several projects for its supply were developed. One foresaw the lifting of the level of the Gérardmer, Longemer and Retournemer lakes by several metres, via the Vologne then the Moselle, to supply the summit reach.

The idea selected was to dam the Avière valley to produce a reservoir fed by a supply channel of 44 kilometres, whose origin is in Remiremont. The final project was presented on 28 November 1876. The reservoir covered an area of 128 hectares and its capacity was 7,073,000 m³.

Work started in 1878 and was completed in 1880. The first filling took place in November 1881, but given that it was performed using only the Avière, the water level rose very slowly.
The main dyke failed on 27 April 1895 (87 deaths) and was re-built in 1930.
