The plant draws water from Mardalsfossen, one of Norway's highest and most famous waterfalls. The power plant also draws operating water from the following lakes: Olaskarsvatnet, Fetjavatnet, Mongevatnet via Monge pumping station, Grøttavatnet, Rangåvatnet and Nedre Mardalsvatnet via Mardal pumping station, and Fossafjelltjønna.

With the use of technical systems and pumping arrangements, Mardalsfossen maintains a minimum water flow of between 2.0 and 2.5 cubic metres per second during parts of the summer season.
