About this map

The agricultural landscape surrounding Somerton is defined by an intricate network of irrigation and drainage infrastructure in the Yuma Valley. The map documents the vital water management systems that support the region, including the Main Drain, Somerton Canal, and numerous lateral waterways like the Faulkner Lateral and Johnson Lateral. These engineering features transformed the desert into productive farmland, supporting the growth of San Luis and residential developments such as Rancho Mesa Verde and Orange Grove Mobile Manor.

Transport and utility landmarks are prominent across the flats, from Somerton Airport to the Rolle Airfield. To the north, the Yuma Indian Homesteads occupy a specific section of the valley, while the eastern edge is marked by the distinct rise of Mohawk Peak. This contemporary survey illustrates the modern layout of E Main St and other local thoroughfares that connect the established town centers with the surrounding agricultural plots.
