Palo Verde Valley agriculture and the engineered hydraulics of the lower Colorado River dominate this landscape near the California-Arizona border. The sophisticated irrigation network is anchored by the Palo Verde Intake in the northeast, feeding a complex system of waterways including the Main Canal, Duplicate Main Canal, and numerous numbered laterals like the D-10 Canal. This infrastructure transformed the arid desert floor into a productive basin, supporting the growth of Blythe and providing the backbone for the local economy.
