The meaning is just 'the river', and this term must have replaced an old name that is now forgotten and unknown. The word lågen is somewhat common in the Norwegian language as a suffix meaning river. The first part of the river name is often the name of the valley in which the river is located (the Gudbrandsdal valley in this case). Examples of this use include Gudbrandsdalslågen, Numedalslågen, and Suldalslågen. Species The Hunder trout is bred at the Hunderfossen waterfall on the Gudbrandsdalslågen river, by the long power station dam. Next to the dam, there is an outdoor exhibition centre for hunder trout. There is a hatchery on the west bank; it produces 20,000 hunder trout every year and releases them into the river to compensate for the loss of fish and of spawning grounds when the power plant was established.
