"Weaving compelling facts and human stories into a cohesive narrative, Boughton explores the dam's political, economic, social, and environmental impacts on the region. He traces the need for a system of dams to control and regulate water; the engineering feats and specific labor skills that would be required to build the great dam at such a breakneck pace; and how the experience shaped the lives of those who built it. .... The book includes numerous well-chosen black-and-white photographs, maps, diagrams, and primary source quotes throughout the text."–The Horn Book
