2022 Map of Dunnigan

About this map

Hershey sits at the junction of rail and road infrastructure in this part of the Central Valley, where the agricultural landscape of Yolo and Colusa counties is defined by a sophisticated network of water management. The terrain transitions from the elevated Dunnigan Hills in the southwest toward the managed lowlands of the Sacramento Valley. This survey highlights the critical role of irrigation and drainage in the region's economy, as seen in the prominent Colusa Basin Drainage Canal and Wilkins Slough Main Irrigation Canal. Local history is preserved in landmarks such as Johns Cem, situated along Mumma RD, and the numerous named county roads that provide a grid for the surrounding farms. Natural waterways like Buckeye Creek and Dunnigan Cr continue to mark the land even as they are integrated into the modern irrigation system.
