About this map

Lake Success dominates the center of this mid-century landscape, a reservoir formed where the Tule River and South Tule River converge. To the west, the expansion of Porterville is evident, showing residential street grids like Morton St and Poplar Ave alongside major local institutions such as the Porterville State Hospital. The map records an era when traditional agriculture and water management defined Tulare County, with numerous gaging stations and a network of ditches feeding the surrounding valley.

Tracing the foothills reveals the area's industrial and social fabric, from the Old Railroad Grade to scattered mining efforts at Mine Hill and Rocky Hill. Local education is well-represented by rural schools including Doyle Colony Sch and Citrus-South Tule Sch. Small settlements and named locales like Lumer, Sunland, and Magnolia provide valuable points of reference for genealogists tracking family locations during this period of California's Central Valley history.
