About this map

The town of Colusa serves as the focal point for this survey of the Central Valley, positioned along a winding stretch of the Sacramento River that includes Cobbs Bend and Arnold Bend. The landscape is defined by an intricate network of water management features essential to the region's agricultural character. This includes the Colusa-Trough Main Canal and the Cheney Slough Irrigation Canal, which navigate the level terrain alongside natural waterways like Powell Slough and Freshwater Cr.

Beyond the structured street grid of the town, the map reveals the layout of the Davis Airport and rural transport routes such as Lurline Ave and Wescott Rd. These roads segment the valley floor into large agricultural parcels typical of Colusa County. Notable natural features like Sabin Lake and Hopkins Slough appear interspersed among the irrigation works, reflecting the area's hydrology before and after modern engineering.
