The Murtensee (outdated Murtenersee , historically Üchtsee ), French Lac de Morat , with an area of ​​22.8 km² is the smallest of the three large Swiss Jura lakes, after Lake Neuchâtel and Lake Biel .


Lake Murten is located in the cantons of Friborg and Vaud . The eponymous city of Murten lies on its southern bank . 40 meters from the north bank, near Guévaux, is the island of La Grande Île with an area of ​​0.1 ha.

The main tributary is the Broye , which drains 63% of the catchment area. The outflow is the Broye Canal, which leads into Lake Neuchâtel . The long-term mean (since 1983) was the water level at 429.30 m above sea level. M. only 2 cm above that of Lake Neuchâtel. Together with Lake Neuchâtel, Lake Murten serves as a compensation basin for the Aare that flows into Lake Biel . When flooding from the Aare causes Lake Biel to rise, the runoff comes to a standstill and at times even flows backwards.

The lake is 8.2 km long and a maximum of 2.8 km wide. Its maximum depth is 45 m, its content around 0.55 km³. The catchment area is 693 km². The theoretical residence time of the water in the lake (filling time) is 1.6 years.

The Murten lake offers various leisure and water sports opportunities; Among other things, there is a sailing school , a surf school and two wakeboard schools .

There are three smaller viewing platforms on the eastern shore of the lake.


During Expo.02 , a rusty, accessible monolith by the architect Jean Nouvel with a side length of 34 meters was floating on Lake Murten, 200 m from the port in Murten, inside of which two panoramic images could be seen (see picture). After the national exhibition it was dismantled again.
