1978 Map of Rio Vista

About this map

The Sacramento River flows past the riverfront city of Rio Vista, anchoring a landscape defined by complex waterways and delta reclaimed lands. By the late 1970s, the area reflects a sophisticated hydraulic engineering system featuring the Yolo Bypass and the Sacramento River Deep Water Ship Channel, alongside vital local infrastructure like the Rio Vista Airport. The map highlights the intersection of agrarian life and industrial energy, with the Montezuma Hills and Rio Vista Gas Field providing a backdrop to the numerous sloughs that carve through Ryer Island and Grand Island. Genealogists will find local institutions such as White Sch and Riverview Sch clearly marked, while the presence of the U S Coast Guard Res underscores the region's importance to maritime safety and navigation within the Sacramento-San Joaquin Delta.
