2015 Map of Zamora

About this map

The Dunnigan Hills dominate the western half of this landscape, descending into the fertile reaches of the Central Valley. The settlement of Zamora serves as a focal point near the eastern edge, situated where the terrain flattens toward the Colusa Basin Drainage Canal. Water management is central to this agricultural region, evidenced by the prominent Tehama-Colusa Canal and a network of seasonal drainages including Bird Creek, Bretona Creek, and Zamora Creek. Between the upland ridges and the basin floor, distinctive depressions such as Bird Valley, Oat Valley, and the evocative Hungry Hollow illustrate the varied topography of Yolo County. An extensive grid of county roads, such as Co Road 99W, connects these disparate elevations, supporting the rural economy and land use patterns of the mid-2010s.
