2012 Map of Moulton Weir

About this map

The Sacramento River meanders through this agricultural landscape, defined by an intricate network of water management features including the Moulton Weir and the Colusa Trough. This 2012 survey illustrates the intersection of industrial farming and conservation, with large tracts of the Delevan Natl Wildlife Refuge interspersed among productive fields. Cultural history is anchored in the south at the Colusa Rancheria and Cachil Dehe Rancheria, while small settlements and river access points like Stegeman, Compton Landing, and Boggs Landing dot the riverbanks. The presence of Gunnersfield Ranch Airport and the complex irrigation system of the Provident Central Canal and Central Drain reflect the intensive land use required for California's Central Valley agriculture. This map preserves a record of the river's path through named features like Hamilton Bend before modern developments or shifts in the waterway occur.
