About this map

The Mokelumne River and San Joaquin River systems define this landscape, where early 20th-century agriculture meets a complex network of sloughs and reclaimed delta islands. At the heart of the northern district, the New Hope (Thornton Migratory Labor Camp) reflects the labor patterns of the Great Depression era, situated near New Hope Landing. The region is heavily marked by the intersection of water and rail transport, with the Western Pacific and Southern Pacific railroads cutting through fertile grounds near Lodi and Acampo.

The map reveals a dense rural infrastructure of the late 1930s, featuring numerous local schoolhouses such as Ray District Sch, Liberty School, and Elkhorn Sch. While the urban center of Lodi shows significant development, the surrounding areas like Staten Island and King Island remain dominated by intricate waterways like Disappointment Slough and Sycamore Slough, which were essential for the movement of goods and irrigation in this central valley hub.
