“Plot Plan - Reception Center, Unit No. 3,” Oversized map of Poston prepared by the Department of Interior, U.S. Indian Service, and the Colorado River Indian Irrigation Project, Arizona, 1943
Poston, the second largest camp, was built on the Colorado River Indian Reservation despite objections from the Tribal Council, which sought to prevent further racial discrimination toward minorities. WRA officials overruled the Council, envisioning Poston’s infrastructure as strategic, long-term investments for the Reservation’s population post-war.
