The Folda (or Folla) is a river in Møre og Romsdal and Trøndelag counties in Norway.[1] The river is part of the Surna watershed and flows into the Surna 7km (04miles) west-southwest of the village of Rindal in the municipality of Rindal in Trøndelag county. It has its source in the Trollheimen mountains on the border of the municipality of Surnadal in Møre og Romsdal county and the municipality of Oppdal in Trøndelag county.[1] The river heads northwards and, for a time, it forms the border between Møre og Romsdal and Trøndelag counties. Two reservoirs lie along the course of the river: Lake Fold (Norwegian: Foldsjø or Follsjø) and Gray Lake (Norwegian: Gråsjø).[1] The Folda has a catchment area of 350km2 and is fed by several tributaries: the Rinna, Bulu, and Vindøla.[1] The name of the river comes from Old Norse Fold, probably meaning 'the broad one'.[1]
