It's more a problem that pretty much any river in the US that is suitable for a large hydro project, already has large hydro projects built in the 1930s through 1960s.
We weren't afraid of mega-dam projects in the past - look at some of the dams on the Columbia as proof, specifically the Grand Coulee Dam which holds back 9 km^3 of water and produces 6800 MW of power - over 3x what Hoover Dam puts out. And it's one of 14 dams on the Columbia.
