  1. “In general, there are three hydropower plants in Russia.” what do you mean by this? that there are 3 arch dams? of course i don’t understand this either as arch dams, even a small arch are MUCH stronger and resist failure as they are under compression. the concrete work here looks better than general, but the maintaince (cleaning, painting looks lacking)
