A large plaque on the AZ side of Hoover Dam contains a 35 year timeline of the development of the Colorado River and building of Hoover Dam, near the elevators that used to take tourists to the AZ power plant.
The Colorado River had been diverted through tunnels around the dam site in 1931. Concrete had been laid to construct the face of the dam starting in 1933. And although water was impounded behind Hoover Dam starting in 1935, that water was not brought through the dam's intakes into the AZ and NV power plants to make hydroelectric power until 11 Sep 1936.
The relevant chronological portion of the plaque reads as follows:
"UNITED STATES OF AMERICA
