2021 Map of Niland

About this map

Niland and Calipatria anchor this 2021 study of the Imperial Valley, where a complex grid of water management infrastructure sustains the desert landscape. The map meticulously documents the extensive system of irrigation and drainage essential to the region, including the Alamo River and alphabetical series ranging from T Drain and S Lateral down to D Lateral W. To the west, the encroaching waters of the Salton Sea surround distinctive landforms such as Mullet Island, Red Island, and Rock Hill, illustrating the evolving shoreline of California's largest inland lake.
