On April 30, many people met in the middle Kamp Valley near Rosenburg to explore it and to demand its protection. On the old dam of the Rosenburg power plant, activists with canoes mounted a large banner demanding the opening of the dam and the liberation of the river. In the video Ulrich Eichelmann, Oliver Lehmann, Doris Knecht, Stefan Glaser und Werner Gamerith explain why they advocate the preservation or restoration of the living, free-flowing Kamp river.
