About this map

The Sacramento River meanders through this agricultural landscape, forming distinct loops like Eldorado Bend and Missouri Bend where the boundaries of Yolo, Sutter, and Colusa counties meet. The interior terrain is defined by the expansive Colusa Basin, a low-lying area managed by the massive Colusa Basin Drainage Canal and an intricate network of levees and pump houses designed to control seasonal flooding. This system of water management transformed the river’s natural floodplains into productive ranch land and orchards.

Industrial and social infrastructure is concentrated along the western edge, where the Southern Pacific railroad line passes through the settlement of Dufour. Local history researchers will find Marys Cemetery located near the center of the sheet, providing a genealogical anchor amidst the surrounding farmsteads. The southwestern corner rises into the Dunnigan Hills, offering a stark contrast to the engineered drainage patterns of the Sycamore Slough and the ancient land divisions of the Jimeno Grant Bdy.
