In 1935, the Boulder Dam, Boulder City, Nev. was dedicated. The concrete-arch dam, subsequently named Hoover Dam (1947), supplied the first U.S. hydroelectric plant to produce a million kilowatts. This production peak occurred in June 1943, though the first of its four generators was placed into operation on 26 Oct 1936. The power serves the Los Angeles area.
