Imperial Valley agricultural infrastructure dominates this 2015 study of the region's complex water management system. The landscape is defined by a dense geometric grid of irrigation channels including the Westside Main Canal, Fillaree Canal, and Tokay Canal, which distribute water across the desert basin. This network is further supported by an intricate series of drains and laterals such as the Thistle Seven Drain and Eucalyptus Lateral Fourteen, illustrating the high-intensity engineering required to sustain cultivation here. The New River cuts through the southern portion of the map, serving as a primary natural drainage feature amidst the human-made grid. The map also records numerous local access roads named for area families or landowners, such as Wieman Rd, Hildebrand Rd, and Swarthout Rd, which provide context for the 21st-century rural development pattern.
