About this map

Porterville State Hospital anchors the southwestern landscape of this Tulare County survey, reflecting California's mid-century institutional expansion. The topography is dominated by the newly formed Lake Success, created by the Success Dam Spillway 652 on the Tule River. This man-made reservoir transformed the local drainage patterns near Rocky Hill and Mine Hill, impacting the agricultural layout of the surrounding valleys.

Rural infrastructure is well-defined, featuring the Atchison Topeka and Santa Fe Railroad and an extensive grid of irrigation ditches and sloughs. Educational landmarks like Doyle Colony Sch and Alta Vista Sch serve the growing residential clusters of Porterville and Porter, while smaller settlements such as Lumer, Magnolia, and Sunland are shown before further suburban development. An Old Railroad Grade near Worth provides a clear view of the area's evolving transportation network as the region shifted toward water management and modern agriculture.
