Hoover Dam Construction 1935

A three million pound gate of tunnel no. 4, shown above at left, was ready to close, Feb. 1, 1935, stopping flow of the Colorado River at the Boulder Dam, thus starting filling of a huge reservoir. The above photo taken just before the gate stated closing shows a coffer dam built across the entrance of tunnel no. 3, which has been diverting the river through the canyon walls and around the dam on the Arizona side.
