El Centro and Imperial anchor this detailed study of the irrigated desert landscape in the heart of the Imperial Valley. The map reveals a sophisticated agricultural grid defined by an intricate network of waterways, including the Central Main Canal, Dogwood Canal, and Eucalyptus Canal, which transform the arid basin into a productive region. This 2015 survey shows the urban development of El Centro expanding toward the Imperial County Airport, while the smaller community of Imperial maintains its own distinct grid to the north. Between these centers, the landscape is etched with countless laterals and drains like Date Lateral Seven and Rice Drain, illustrating the critical role of water management. Researchers will also find smaller locales such as Wilsie and Anza, along with local institutions like Imperial Valley College and the Evergreen Cemetery.
