About this map

Holtville serves as the primary hub in this highly engineered landscape, where the Alamo River snakes through an intricate grid of irrigation infrastructure. This 1945 survey by the War Department reveals the intensive transformation of the Imperial Valley, defined by a dense network of canals and drains such as the Rubber Canal, Rose Canal, and the Holtville Main Drain. The presence of numerous rural schoolhouses, including Union Sch, Sunset Springs Sch, and Alamitos Sch, indicates a robust agricultural community supported by these water systems.
