About this map

Rio Vista serves as the focal point of this Sacramento River delta survey, situated where the river meets the vast lowlands of the Yolo Basin. The topography reveals a striking contrast between the elevated, contour-rich Montezuma Hills to the west and the intricate maze of sloughs and reclaimed lands to the east. This early 20th-century landscape is defined by its waterborne geography, featuring a complex network of channels including Cache Slough, Steamboat Slough, and Lindsey Slough that carve out major landmasses like Ryer Island and Grand Island.

Local industry and early infrastructure are evident through specific markers such as a Blacksmith Shop south of the hills and a Pumping Plant on the edge of the basin. The settlement of Newtown appears as a small riverside cluster north of the primary town, illustrating the early footprint of habitation before modern levee and drainage developments fully transformed the delta’s seasonal wetlands and agricultural islands.
