About this map

The delta landscape of the lower Sacramento River valley is defined here by a complex network of man-made and natural waterways. The Sacramento River Deep Water Ship Channel dominates the eastern half of the map, carving a straight path through the Yolo Bypass and creating a stark contrast to the winding channels of Cache Slough and Miner Slough. This region is divided into distinct reclamation areas like the Maine Prairie Tract and the Hastings Tract, where a reliance on pumping stations reveals the perpetual effort to manage water levels on these low-lying islands. Land use is largely agricultural, centered around the settlement of Liberty Farms. To the north, the Millar Gas Field indicates the subsurface industrial value of the land, while family-named roads like Winship Road and Sikes Road provide a record of local landownership during the late 1970s.
