Fresh water in Luxembourg?

The north eastern part of Luxembourg has hills, valleys and extensive woodlands, and not all that many inhabitants. I roughly followed the valley of the Our river. Many little streams like this one come down the slopes from the high plateau to the west, drain into bigger ones before finally reaching the Our. Nice hiking country! By the way, although it looks fresh, I wouldn't drink this water without treatment. There are cows on the high plateau! May 18, 2007.
