1955 Map of Imperial Reservoir

USGS Topo · Published 1956

About this map

Imperial Reservoir and the Colorado River dominate this mid-century landscape along the Arizona-California border. The map captures the intricate water management infrastructure of the era, including the Imperial Dam Spillway 181 and the Gila Main Canal. While the water provides a focus for recreation at Martinez Lake and Fishers Landing, the surrounding desert terrain is defined by the Chocolate Mountains and extensive washes like Senator Wash and Los Angeles Wash.
