With the first full reservoir in 1969, the Mattmark dam facility went into commercial operation.

The facilities of Kraftwerke Mattmark AG were, with the exception of the Zermeiggern pumping station, built between 1958 and 1966. The Zermeiggern pumping station was constructed between 1983 and 1987. With the first full reservoir in 1969, the Mattmark dam facility went into commercial operation. It holds 100 million m3 of water and was constructed solely for the purpose of generating electrical energy. In addition to the 37.1 km2 catchment area, the streams on the left and right shore of the Saaser Vispa, with a catchment area of 51.1 km2, are fed into the Mattmark reservoir. 45 per cent of the catchment area is glaciated. The headquarters of Stalden can be reached from Visp (VS) by public transport or by car in 13 minutes.
