Historic Maps of the Delta:  1900 to 1939  
Note that you can "click" on each picture to see an enlarged version of the picture.  Maps were found online or scanned from old books, and then were cropped to show the Delta area only.  When available, the original map author or surveyor and its original publication date are provided.  By using the information, you may be able to research online to find full versions of the maps.

Note regarding the above map:  it was photographed on the wall at the Yolo bypass maintenance office area, but we have not seen that map otherwise in any other records.  The date of the map came from a white label added-no date showed on the map.  Therefore this may not be an authentic map but a planner's rendering from the 21st century.
