1940 Map of Alamorio

USGS Topo · Published 1956

About this map

The Alamo River winds through an intricately plumbed desert landscape in this mid-century Imperial County survey. The region is defined by a dense grid of irrigation infrastructure, with alphabetically organized channels such as the Moss Lateral, Ohmar Lateral, and Pansy Canal supporting the agricultural expansion of the valley. Holtville serves as the primary hub, surrounded by smaller siding settlements and rural junctions like Alamorio, Sandia, and Meloland.
