The border city of Calexico serves as the focal point of this 2012 survey, situated at the edge of the Imperial Valley's complex irrigation network. The landscape is defined by an intricate system of engineered waterways, including the prominent All-American Canal and the Central Main Canal, which feed a grid of laterals and drains such as the Ash Main Canal and Birch Canal. This hydraulic architecture transforms the arid terrain into a productive agricultural zone, evidenced by the numerous named drains like Alamitos Three Drain and Schenk Seven Drain that crisscross the farmland north of the international boundary.
