"We got into what I call now the little puddle that was the lake at that time, and we went up to the back part of the dam, and this great big structure, this, oh my God... big hunk of concrete, corkin' up the Colorado River. And the intake towers sitting on the cliffs, way up above us. Now when you go over the dam it looks like the intake towers are right in the middle of the lake, you know, and the dam, you only see a small portion of it. "70 - Ila Clements-Davey "My job, with the crew that I was working for, was to move them penstocks out from the plant... Every time you'd move a pipe, you'd have to build a railroad line... You'd have to jack [the pipe] up, and they'd have two big timbers underneath each 30-foot penstock... to handle the weight. Then on each corner we had a skip [and] two men on each corner. We had eight five-pound bores about two or three inches in diameter [to help roll the pipe section]. You had about six or eight of them on each corner. You had to keep them under that corner. If you missed one just a fraction just a second too late, we 'd have to stop because they 're so heavy. You d have to jack the pipe up, and put one under there."71 Dean Pulsipher As the dam rose between the canyon walls, construction began on the power plant, below the dam on the upstream side, and on the intake towers, above the dam on the downstream side. The Babcock & Wilcox Company was awarded a contract to build and install penstock pipes in tunnels that angled from the inner diversion tunnels down to the powerhouse, where the flow of water would spin the turbines and generate electricity. Here, a 30-foot pipe section is lifted from a trailer.
