About this map

Tranquillity and the rail-stop at Jamesan anchor this section of the San Joaquin Valley during the early 1960s, a landscape defined by industrial agriculture and complex water management. The Southern Pacific railroad cuts through the terrain, connecting small rural hubs to the broader California economy. This era reveals a sophisticated irrigation and drainage network, highlighted by the massive James Bypass and the winding course of the Fresno Slough.

Evidence of the local ranching and farming infrastructure is everywhere, from the Traction Ranch to the numerous wells and siphons that dot the grid. The naming of roads like Contra Costa Avenue, El Dorado Avenue, and Napa Avenue suggests an organized expansion of the valley floor. These features, along with the Duck Ponds and a Gaging Station, illustrate how the natural hydrology of the region was being meticulously controlled for large-scale cultivation.
