In the northeast of the Fulufjälls the water of the stream Njupån rushes out of the lying on the summit plateau lakes Storrörsjön and Lissrörsjön a between 800 m and 900 m ö.h. lying escarpment down into a steep ravine. After a few kilometers the Njupån flows near the village Mörkret into the river Fuluälven.
