2018 Map of Zamora

About this map

Zamora anchors this agricultural corridor of Yolo County, situated where the flat Sacramento Valley floor begins to rise into the undulating terrain of the Dunnigan Hills. The landscape is defined by its complex water management and drainage systems, including the massive Colusa Basin Drainage Canal and the Tehama Colusa Canal, which slice across the valley to support the region's productive farmlands. In the west, the topography transitions from the alluvial plains of Bird Valley and Oat Valley into the more varied elevations of Hungry Hollow. This 2018 survey captures the intricate network of county roads, such as Co RD 99w and Eucalyptus Rd, that link the various agricultural holdings and creek beds. Seasonal drainages like Zamora Creek, Bird Creek, and Willow Spring Creek meander through the hills, illustrating the natural watershed patterns that predate the modern canal infrastructure.
