1956 Map of Tranquillity

About this map

Fresno Slough meanders through the heart of this Central Valley landscape, defining the character of the Mendota Wildlife Management Area. The map reveals a complex water management system essential for regional agriculture and conservation, featuring Fish Rearing Ponds and the James Bypass. Transport networks of the mid-1950s are represented by the Southern Pacific railroad line and the Santa Fe Grade, which cut through a grid of rural roads named for California counties. The small settlements of Tranquillity and Mendota anchor the corners of the sheet, while family-held land like Yearout Ranch and the rail siding at Ingle suggest the area's deep-rooted agricultural identity. This survey captures a moment before modern industrial shifts, showing the reliance on levees and pumps to manage the low-lying terrain.
