links to pictures of historic maps of California and the
Delta region. We have so many maps now, we try to split them
into different pages, by years. Some of the highly detailed
and large maps of the survey of the San Joaquin River and the
Atwater maps have been added to
http://www.archive.org so that is a good research place too
if you want to see some historic Delta maps. Click on the map thumbnails to
see larger versions. Much of the last 150 years of California Delta
history can be quickly gleaned by review of the maps over time.
More maps and links added
as time allows.

Maps were found online or
in old books, then scanned and cropped to show the Delta area only.
When available, the original map author or surveyor and its original
publication date are provided. It has been assumed all these
older maps are out of copyright term, and this information is
provided for educational purposes as it is exactly that
reason the maps and old documents are being provided online herein. By using the map
information, you may be able to research online to find full
versions of the maps. We also suggest you go to the Rio Vista
Museum, as it has several great maps in frames on the walls!
You might also want to check with the California & Sacramento Historical Society,
the Dutra Dredge Museum, and the Delta King, a floating paddle
wheeler located at the Old Sacramento waterfront. However,
oddly, the official California State Museum in California removed
many of the historic maps on the walls and put up a new map that
shows the Sacramento River as merging with the Mokelumnke River
instead of its actual natural or historic pathway past Isleton and
Rio Vista. The map change happened in the reign of Governor
Schwartzenegger-it might still be there in the museum!
