The Rauma is a river that runs through Romsdalen, a valley in Møre og Romsdal and Oppland counties in Norway. It runs for from Lesjaskogsvatnet, a lake in the municipality of Lesja, to the town of Åndalsnes in the municipality of Rauma. The river was once famous for its salmon-fishing, but since an infection with Gyrodactylus salaris only 5 to 10% of the original stock survives. The salmon runs up to the Slettafoss, a high combination of waterfalls and rapids more than upriver from the estuary.
