1907 Map of Colusa

About this map

Colusa serves as the focal point for this early 20th-century survey of the Sacramento Valley, where the town layout is shown situated along a prominent bend in the river near Sabin Lake and Cobbs Bend. The map illustrates a landscape undergoing significant transformation through water management and rail expansion. The Southern Pacific (Woodland Line) bisects the territory diagonally, connecting the agricultural hubs of Williams and Arbuckle, while the Colusa and Lake railroad heads west from Colusa Junction. Extensive irrigation infrastructure, including the Cheney Slough and Irrigation Company Canal and Lurline Canal, highlights the shift toward systematic cultivation. Along the eastern edge, the Davis Levee and Old Davis Levee trace the historical efforts to control seasonal flooding from the sloughs and the river.
