In his comprehensive history of western water development, "Cadillac Desert" (1986), Marc Reisner criticized the political forces that resulted in Glen Canyon and hundreds of other dams being built in the 1960s and 1970s. Many of these projects had dubious economic justifications and hidden environmental costs, but the government agencies that built them – namely the Bureau of Reclamation and the U.S. Army Corps of Engineers – were more interested in maintaining their size and influence. Reisner writes that "in the West, it is said, water flows uphill towards money."
