I think the resevoir fills up on this side of the dam.
I guess I need to look at the picture again, huh? Thanks. :-)
It does, the reservoir drained... either they use a whole lot of water or it hadn't had a lot of time to fill, because there should be a lot more water behind that dam, it sounds like the engineers are downplaying the whole thing. Dams are a part of life in my part of the country and cracks like that would tell us that they didn't cure properly or used sub-standard cement. Curing these dams is very a delicate matter.
