About this map

The Imperial Valley landscape is defined by an intricate, geometric network of irrigation infrastructure designed to transform this arid basin. Settlements like Wiest and Munyon anchor a grid of agricultural commerce, sustained by a complex system of water delivery and drainage. The Vail Supply Canal and numerous named laterals, such as the Mayflower Lateral and Nectarine Lateral, demonstrate the intensive engineering of the desert floor.

Natural and managed water features provide the only break in the rectilinear pattern. The Alamo River meanders through the western section of the map, adjacent to Wiest Lake and Finney Lake. These riparian zones contrast sharply with the surrounding drainage channels like the Standard Drain and Mullen Drain. For those studying the evolution of industrial-scale farming, the map provides a precise record of how water rights and land management shaped this portion of California.
