1948 Map of Delta Ranch

About this map

The San Joaquin River and its complex network of sloughs and irrigation works define the agricultural landscape of Merced County in this mid-century survey. Irrigation infrastructure, vital to the region's productivity, is meticulously documented through features like the Colony Main Canal, San Juan Canal, and Agatha Canal, alongside numerous drainage systems such as the West Delta Drain. The map reveals a settlement pattern dominated by large agricultural holdings and company lands rather than traditional townsites, specifically naming the namesake Delta Ranch, San Juan Ranch, and Devon Farm. At the southern edge, the Southern Pacific railroad provides a vital link for moving goods from these inland farms. Local landmarks like the Gaging Sta on the river and the stop at Agatha offer specific points of interest for those tracing the development of Central Valley water management and transit.
