2015 Map of Cortina Creek

About this map

Spring Valley serves as a distinct transitional landscape on this 2015 map, where the western foothills meet the broad agricultural expanses of the Sacramento Valley. The area is defined by an extensive network of water management, most notably the Tehama Colusa Canal and the Glenn-Colusa Canal, which cut across the terrain to support regional irrigation. These man-made waterways intersect natural drainages like Cortina Creek and Spring Cr, illustrating the complex engineering required to manage water in this part of California.
