Also try a google earth sat pic of the dams now, when I flew over them you could still see the patches
No need for Google, or flying:
The damage to the wall of the Eder Dam is clearly evident, even in 2005 when I took this picture - they're still working on it too!! Note the lack of sluices/arches about 1/3rd of the way down the dam wall towards the lefthand side, and the different coloured bricks (red) used in the upper arches in the same area. Note the castle in the background - Schloss Waldeck, which was used on the run-in to the target.
