Hey denyd, (and all others) you cannot build Hoover Dam without a river. A lake simply will not do. Once as the Americans I had 3/4 of a continent while the Aztecs had the other quarter and the only river on the entire continent. In the whole of my territory the only fresh water I had was a one tile lake, on the shore of which I built the city of Detroit. In this particular game I was leading in tech and production and was eager to build Hoover's in Detroit, but I could not. I had to conquer the Aztec capital and hurry the wonder with a leader. So even though a lake eliminates the need for an aqueduct, It doesn't have the current needed for a hydro plant.
I have noticed the same when playing CIV Vanilla, but when I moved to PTW 1.14 I could build Hoover in a city located near a lake.
