About this map

The Sacramento River dominates the eastern boundary of this landscape, its winding course forming prominent features like Hamilton Bend near the southern edge. This area of Colusa County is defined by a sophisticated water management network designed for the Central Valley agricultural economy, including the Colusa Trough, Provident Central Canal, and the Main Canal. The small settlement of Stegeman sits tucked against the river, while the western portion of the map transition into the wetlands of the Delevan National Wildlife Refuge Rd. Local aviation is represented by Gunnersfield Ranch Airport and Richter Aviation, supporting the region's farming operations. Numerous named water bodies like Hopkins Slough, Stone Corral Cr, and Willow Creek illustrate the complex hydrology of this low-lying riverine environment.
