1939 Map of Lodi

About this map

The delta wetlands and fertile agricultural plains of northern San Joaquin County define this landscape at the dawn of the 1940s. The Mokelumne River and its intricate network of sloughs, including Beaver Slough and Hog Slough, segment the territory into distinct land masses like Staten Island and King Island. The core of Lodi is shown alongside satellite communities such as Woodbridge and Acampo, reflecting an era of expanding irrigation and transit. Of significant social interest is the New Hope Thornton Migratory Labor Camp, a site providing rare spatial context for the region's agricultural history. Dozens of rural schools, including Liberty School and Ray District Sch, are scattered throughout the quadrangle, serving families established near the Western Pacific and Southern Pacific railroad lines.
