2015 Map of Moulton Weir

About this map

The Sacramento River defines the eastern boundary of this landscape, its winding course marked by hydrological features like Hamilton Bend and the essential infrastructure of the Moulton Weir. This 2015 survey reveals a terrain meticulously managed for water distribution and conservation within the Sacramento Valley. A complex network of irrigation and drainage channels, including the Provident Central Canal, the Colusa Trough, and the Northeast Drain, crisscrosses the agricultural flats. Cultural and civic footprints are visible at the Colusa Rancheria and the settlement of Stegeman, while the western portion of the map is dominated by the Delevan National Wildlife Refuge. Regional aviation is represented by private facilities such as Gunnersfield Ranch Airport and Richter Airport, serving the agricultural operations of this fertile river corridor.
