1954 Map of Grimes

About this map

The Sacramento River meanders through this agricultural corridor of the Sacramento Valley, defining the eastern edge of the quadrangle with its distinctive oxbows and river bars. The settlement of Grimes serves as a central hub, adjacent to Grand Island School and the Grand Island Cemetery. This landscape is fundamentally shaped by the movement of water and rail, with the Southern Pacific tracks cutting across the basin to reach points like Sycamore Siding and Grains. The intricate network of drainage features, including the Colusa Basin Drainage Canal and numerous sloughs like Sycamore Slough, highlights the complex irrigation and flood control engineering required to maintain the productivity of the Colusa Basin and Jimeno Basin. Numerous landing strips and gages indicate the area's mid-century reliance on both small-scale aviation and careful river monitoring.
