The Lac de Tseuzier reservoir is located in the canton of Valais in the municipalities of Ayent and Icogne .
The lake can be reached via the Rhone Valley . From Sion you drive to the last larger town of Fortunau. Then a serpentine mountain road leads to the reservoir. You can also walk to the lake via the Rawilpass or the Schnidejoch from the canton of Bern .
history
The Zeuzier arch dam and the Proz-Riond earthfill dam were completed in 1957.
Remarkable
Originally, the Simmental motorway (at that time still the N6 national road ) was supposed to be led over the Rawil Pass into the Valais - a tunnel would have come close to the Tzeuzier dam. Since larger movements than expected occurred in the wall during exploratory drilling, not only was the lake level lowered; it was one of the reasons that the autobahn had been delayed for years until it was finally abandoned. With the Lötschberg base tunnel it became completely obsolete.
To the west of Lac de Tesuzier is the mountain Six des Eaux Froides (2905 m above sea level).
