About this map

The Sacramento River defines the eastern boundary of this agricultural landscape in the early 1950s, a period when complex irrigation and flood control systems were central to the region's productivity. The map details a network of vital waterways including the Main Canal, Colusa Canal, and Provident Canal, interspersed with levee systems and numerous siphons. The Southern Pacific railroad line runs parallel to the river, serving local shipping points like Glenn Siding and the settlement of Glenn.

Cultural landmarks of the era include the Larkins Children s Rancho and Jacinto Grange, reflecting a community structured around ranching and collective agricultural life. Smaller settlements such as Bayliss and Jacinto are documented alongside specialized infrastructure like the Pumping Plant and the gas wells located in the western sections. The presence of Hartley Island and Sidds Landing highlights the historical importance of river access before the modern road network fully dominated California's Central Valley.
