2012 Map of Dunnigan

About this map

Agricultural patterns and irrigation infrastructure define the landscape around Dunnigan in the early 21st century. The town, along with the settlement of Hershey to the northwest, sits at the base of the hills, where the terrain transitions into the flat expanse of the Sacramento Valley. This area is heavily defined by its water management systems, notably the massive Colusa Basin Drainage Canal and the Wilkins Slough Main Irrigation Canal, which service the grid of farmland. For those tracing local history, the Johns Cem and roads like Johns School Rd provide evidence of earlier family names and rural school sites. The path of Old Hwy 99W runs parallel to the modern interstate corridor, marking the historical transit route through this portion of Yolo County. Natural drainage is still visible through seasonal waterways like Buckeye Cr and Dunnigan Cr.
