The dam+reservoir dates back to 1954-1964 (
http://www.eifelfuehrer.de/V/Vianden.html ).
The photo at
http://www.engineering.uiowa.edu/~cfd/gallery/images/hyd24 isn't the
Vianden dam, I think, but another one (possibly the one in the Sauer
at Esch-sur-Sûre). I can see that because at Vianden there isn't a
road on the right bank near the dam (the bank is very steep there),
and, according to my map, the dam is straight rather than bent. So
the Univ. of Iowa has made a mistake here.
Anyway, a map (without boundaries) can be found at
http://www.restena.lu/meteo_lcd/papers/radon/seo2000/investigations.ht
ml . The Bassin Inférieur is depicted dark blue. The boundary runs
over the ridge of the promontory which can be seen just to the north
of the bridge over the reservoir, left bank. At the tip of it is one
of the no. 47 stones; the other one is on the opposite bank, very
close to the bridge and road.
I will try to post a scan of my map here soon, but because my scanner
is behaving funny lately, I don't know if I'm going to be able to do
this.
