“This waterfall in the Tungnaá River is 29m high and is not far above the confluence of the Tungnaá and a branch of the Köldukvísl. Above the falls there are several small islands, Hrauneyjar, well vegetated. Below the falls is an awesome gorge. Today the water in the Tungnaá at Hrauneyjafoss has been harnessed, construction having started in 1978 and the power plant completed in December
1982. There is a dam 1½ km above the falls that forms a large reservoir and has flooded Hrauneyjar.”
After the Hrauneyjarfoss power plant was taken into use the waterfall was flooded out. What is visible today are rapids where the waterfall was, but only those who know where to look can find it.
