Description of the Watercourses SuldalslAgen (fig. 1,l) has been described by A. Lillehammer (1964 and 1965). Its water supply comes mainly from the melting snow on the high mountain plateau, the greatest flow of watcr being in the summer months (fig. 2). The temperature, therefore, is comparatively low at the and of June when the melting of the snow culminates; there upon, the temperature rises until August when it is at its highest. Storelva (fig. 1,2) flows through the district of Sauda. Its precipitation area is 358 m2. It is a short but well-filled watercourse and obtains its natural intake from the melting snow on the highland plateau. At Storlidam, however, this is all directed into a pipe-line and carried to the power station at the fjord-side. There is thus left the intake from the lower mountain areas where the melting of the snow takes place mainly in the Spring. The flow of water has a tendency to decrease in July and August. During this period the water level can be so very low that, occasionally, the water just about flows. Moss vegetation found included Fontinalis dalecarlica and Marsupella emarginnta. Algae vegetation is also common in some parts of the river. Whereas the size of the stones in Suldalsl5gen (fig. 3) is very uniform, in Storelva (fig. 4) there is considerable variation. Suldalslagen (fig. 5) therefore flows more evenly and more quietly than Storelva where the conditions of the current are quite
