About this map

The San Joaquin River meanders through this agricultural landscape, bordered by an intricate system of levees and sloughs like Walthall Slough. The 1952 landscape reflects a critical era of California water infrastructure, showcasing the Delta-Mendota Canal and the Hetch Hetchy Aqueduct as they traverse the valley floor. Near the river, the San Joaquin City (Site) marks the location of a former settlement, while the San Joaquin River Club indicates mid-century riverside development.

Transportation and institutional presence are defined by the competing routes of the Southern Pacific and Western Pacific railroads. The map records the Deuel Vocational Institution and the New Jerusalem School, alongside small rail stops like Yarmouth and Rhodes. This survey provides a window into the region's transition, as industrial-scale water management began to reshape the old river crossings and ranch roads.
