The Colorado River serves as the central artery for this complex borderland landscape, where the diverted waters of the Main Canal and Alamo Canal fuel the intensive irrigation of the Yuma Valley. This region is defined by its international and interstate boundaries, where the United States Mexico border meets the California Arizona line near the Andrade site. The engineering of the desert is evident in the network of drains and laterals, such as the Central Drain and Howe Lateral, which support the University of Arizona Agricultural Experiment Sta.
