The lake is a reservoir for the Rud hydroelectric powerstation in Hovet.
In 1952/1953 a dam was constructed which lifted the lake level 28 meters, thus the lake varies between 950 and 978 m above sea level.
There is a dam at Strandavatnet. In fact it was the first rock filling (embankment) dam in Norway. You can see it on your left hand side from Riksvei 50 at Myrland (the road to Raggsteindalen goes over the dam).
