The Doctrine of Domination: Why America Dammed the West

To the generation that settled the arid West, a river running free to the sea looked like wasted water and unharvested power. The episode traces the idea behind the dams: Manifest Destiny reworked as an engineering faith, the 1902 Newlands Reclamation Act, the rise of the Bureau of Reclamation and the Army Corps of Engineers, and John Wesley Powell's warnings about aridity that Washington ignored.

Still debated

The central question is whether dam-builders acted from good-faith ignorance, willful indifference or self-interest; Powell's warnings show the information existed. Historians also differ on how sincere the reclamation movement was versus cover for speculation and agribusiness.
