（重定向自Lagen）
The Gudbrandsdalslågen (or the Lågen) river flows through the Gudbrandsdal of Norway.
The Gudbrandsdalslågen begins in the lake Lesjaskogsvatnet (or Lesjavatn), which lies in Lesja municipality in Oppland. Lesjavatn is the only lake in Norway which has two outlets; they flow into two of Norway’s more famous rivers. In the southeast at Lesjaverk village the lake serves as the headwaters for the Gudbrandsdalslågen, while in the northwest at Lesjaskog village, Lesjavatn is the headwaters for the Rauma river.
