1955 Map of Imperial Reservoir
USGS Topo · Published 1983About this map
Imperial Reservoir and the Colorado River dominate this mid-century landscape along the Arizona-California border. The infrastructure of the Imperial Dam Spillway 181 and its associated Desilting Tanks highlight the heavy engineering required to manage the river's flow for the surrounding desert. The presence of the Yuma Test Station and the Refuge Boundary Military Reservation underscores the region's transition into a specialized military and conservation corridor during the 1950s.
