About this map

The Sacramento River defines the eastern boundary of this agricultural landscape, where the town of Colusa serves as a central hub for the surrounding Colusa County farmlands. The map reveals an intricate network of water management features essential to the region's valley floor, including the Colusa Trough and the Cheney Slough Irrigation Canal. These man-made and natural waterways, such as Hopkins Slough and Powell Slough, underscore the area's transition from riparian wetlands to productive agriculture.

Northwest of the main town, the Colusa Rancheria stands as a distinct community, while smaller intersections like The Four Corners mark rural navigation points. Local infrastructure is evidenced by the Davis Airport and flood control measures including the Davis Levee and Old Davis Levee. Significant river bends, specifically Cobbs Bend and Arnold Bend, highlight the river's historical path and its influence on local topography.
