1948 Map of Llano Seco

About this map

The Sacramento River defines the western edge of this landscape, its wandering course creating a complex network of meanders and water features like The Lagoon and Hartley Island. This 1948 survey shows a region deeply tied to its Mexican land grant history, with expansive tracts such as Rancho De Farwell and the Larkins Children Rancho still clearly delineated. The land is crisscrossed by sloughs and seasonal lakes, including Perkins Lake and Angel Slough, which speak to the natural flood patterns of the valley floor before mid-century agricultural engineering fully took hold.
