The river Døgro plunges down from the Døgrdalsvatnet over a heigh of 600 meters. Probably I am the only one that noticed the fall. It is also an unofficial name I gave to the waterfall.
I am not 100% sure the photo is the river Døgro, but if I inspect the map the river Døgro is the only river with a reasonable flow. So it must be right.
