Until 1743 the people from Modal had to wait for a flood in MOSTRAUMEN before they could draw their boats up the river current, and then row back across Lake Movatnet. But, that year the flood opened a free passageway all the way to Mo. Hordaland had gained a new tidal waterway.
The large mountain area between Modalen, the Voss communities and Sogn is one of the finest mountain pasture areas in West Norway. In older times this area was called Steinslandsheimen, in our times it has acquired the name Stølsheimen. Power development and protection interests have been opposed here. The core area of Stølsheimen has now been protected as a landscape protection area, while some of the oldest mountain farms have been flooded. A register in the 1970s comprised almost 40 mountain farm settlements in the central area of Stølsheimen, belonging to Modalen, Høyanger and Vik municipalities.
