About this map

The Colorado River and Gila River converge in this mid-century desert landscape, dominated by the massive water management infrastructure of the Imperial Reservoir and Imperial Dam Spillway. The map details the complex irrigation network that transformed the region, featuring the All American Canal, Gila Gravity Main Canal, and Wellton-Mohawk Canal. On the Arizona side, the Yuma Test Station occupies a significant portion of the terrain between the Laguna Mountains and the Castle Dome Mountains.

For those tracing industrial and maritime history, the map preserves the locations of old river access points like Castle Dome Landing and Fishers Landing, alongside mining sites such as the Old Senator Mine and Las Flores Mine. The Southern Pacific railroad follows the Gila Valley through Kinter, crossing near the historic Mc Phaul Bridge. The presence of numerous washes, including Vinegarroon Wash and Castle Dome Wash, illustrates the drainage patterns through the Middle Mountains before reaching the cultivated river plains.
