Mjøsa

Historie

Mjøsa is Norway's largest lake, as well as one of the deepest lakes in Norway and in Europe. It is the fourth-deepest lake in Norway. It is located in the southern part of Norway, about 100 km north of Oslo. Its main tributary is Gudbrandsdalslågen in the north; the only distributary is Vorma in the south.LocationFrom its southernmost point at Minnesund in Eidsvoll to its northernmost point in Lillehammer it is 117 km long. At its widest, near Hamar, it is 15 km wide. It is 365 km² in area and its volume is estimated at 56 km³; normally its surface is 123 metres above sea level, and its greatest depth is 468 metres. Its total coastline is estimated at 273 km, of which 30% is built up. Dams built on the distribuary of Vorma in 1858, 1911, 1947, and 1965 raised the level by approximately 3.6 metres in total. In the last 200 years, 20 floods have been registered that added 7 metres to the level of Mjøsa. Several of these floods inundated the city of Hamar.The cities of Hamar, Gjøvik, and Lillehammer were founded along the shores of the lake. Before the construction of railways past the lake, it was an important transport route. Today, aside from minor leisure boating and the steamship Skibladner, there is no water traffic on the lake. Most of its shores are dominated by rolling agricultural areas, among them some of the most fertile grainlands in Norway. The main train line, the Dovre Line between Oslo and Trondheim, goes along its eastern shore, making stops in Hamar and Lillehammer. From the south European route E6 runs along the eastern shore of the lake until the Mjøsa Bridge connects Moelv on the east with Biri on the west.
