Its main tributary is Gudbrandsdalslågen in the north; the main distribuary is Vorma in the south.From its southernmost point at Minnesund in Eidsvoll to its northernmost point in Lillehammer it is 117 km long. At its widest it is 15 km wide. It is 365 km2 in area and is about 180 meters deep, on average.
The cities of Hamar, Gjøvik, and Lillehammer were founded along the shores of the lake. 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.
