The Bouzey channel ensures the supply of water to the Vosges canal. At Saint-Etienne-lès-Remiremont, part of the Moselle’s flow is deviated into the channel, where it flows by gravity over more than 45 kilometres, to the Bouzey reservoir. From there, it flows into the Vosges canal and covers the navigation needs.
This channel is made up of three sections:
1. The main channel, of a length of 45.379 km, supplies the Bouzey reservoir.
2. The auxiliary channel, of a length of 1.054 km, allows the direct supply of the Vosges canal, without going via the reservoir.
3. The secondary channel, of a length of 0.435 km, which starts at the base of the reservoir dyke and flows to the summit reach.
In total, the channel represents a length of 46.868 km, over which the following can be found:
16 tunnels (including the Chantraine tunnel of a length of 1.533 km) and 7 sections under roads
10 siphons, including that in Niche: 284 m, Nauves: 159 m, Dinozé: 272 m and Saint-Laurent: 229 m.
