Schiffenen arch dam

The Schiffenensee is located in the Swiss canton of Friborg . The districts of See , Sense and Saane border the lake. In Granges-Paccot the motorway crossing A12 the reservoir. One kilometer to the south-east is the Grandfey Viaduct , a railway bridge that also crosses the narrow lake.

The steadily increasing demand for electricity prompted FEW (Freiburgische Elektrizitätswerke, today Groupe E ) to commission a study on the construction of a new hydropower plant on the Saane.

Two options were examined:

  • to leave the Saane in the old river bed
  • divert the Saane into the Murten lake

A diversion into Lake Murten would have had an impact beyond the canton of Friborg. The FEW were not happy with the submitted projects and they gave another office the contract to revise the studies again. Various possibilities were then presented. The projects showed the following studies:

The solution Schiffenen promised a larger reservoir than the other proposals. The advantages for ships were:

  • The power station could be built at the foot of the wall
  • No tunnels had to be built
  • No conflicts with the neighbor Bern
  • FEW was able to carry out the construction on its own.

The decision was made to build an arch dam in ships. The Grand Council of the Canton of Friborg approved the project at its meetings on November 20 and 24, 1959.

The foundation stone for the construction of the Schiffenen dam wall was laid in 1959. In 1960 all work was awarded and construction could begin. The Schiffenen dam was completed in 1963 .

Technical data of the dam

Storage volume: 65 million m³


At least 15 suggestions were under discussion as a name for the new lake. The final designation by the Freiburg State Council took place in 1964 after a report by the Freiburg German Studies professor Eduard Studer .
