ABSTRACT

Thus, after many years of discussion and study, construction began in the middle 1950s on a massive dam in Glen Canyon on the main stem of the Colorado River just below the Utah-Arizona state line, more or less in the middle of the Poverty Diagonal. It was to impound a large water body known as Lake Powell. From that time through the early 1960s, a large work force was employed in construction of the dam, Arch Bridge, below the dam and the hydro power units. Because of available cooling water and nearby coal supplies, a 2,250 megawatt power plant was constructed in the early 1970s and a coal mine was opened at nearby Black Mesa. Both the power station and the coal mine are on Navajo land. Figure 2-1 on page 9 shows what we term "the Lake Powell Region."
