The Mightiest of Them All: Memories of Grand Coulee Dam by Leonhard Vaughn Downs is a detailed historical memoir and engineering retrospective, published in 1986 by the American Society of Civil Engineers, that chronicles the monumental construction of the largest concrete structure in the United States. Written by a Bureau of Reclamation engineer who spent decades working intimately on the Columbia Basin Project, the book offers a rare insider's perspective on the massive Depression-era public works endeavor. It details the formidable technical challenges, the massive labor force, and the daily realities of taming the Columbia River to generate hydroelectric power and provide regional irrigation. Ultimately, it serves as an invaluable firsthand account and a tribute to the ingenuity, grit, and colossal scale of federal infrastructure development that fundamentally transformed the landscape and economy of eastern Washington.
