Cadillac Desert (1986), is a history by American Marc Reisner about land development and water policy in the western United States. Subtitled The American West and its Disappearing Water, it explores the history of the federal agencies, Bureau of Reclamation and U.S. Army Corps of Engineers, and their struggles to remake the American West in ways to satisfy national settlement goals. The book concludes that the development-driven policies, formed when settling the West was the country's main concern, have had serious long-term negative effects on the environment and water quantity. The book was revised and updated in 1993.
