Surveys of Sacramento and San Joaquin Delta lands over the years
Due to the large number of maps, each of which are large files to upload, this section is being divided into numerous pages based on
when the maps were first published.  Reorganization of the historic map pages should be completed by December 2013 and hundreds
of new maps and historic documents have been added.

In the meantime, below are links to pdfs or jpgs of survey sheets we scanned so you could see what the specific areas of the Delta looked like
at specific time frames in history.  Survey maps are different from other historical maps because they were submitted and
approved by either the state or federal governments, were made for a specific purpose, and were usually very large or had
many large sheets to allow for the details of the survey:  land elevation, land mass, vegitation, soil type and other important
land factors.  These files are very large and detailed.  As time allows, we are scanning two important official survey sets we
have:  1906 survey of the San Joaquin River and the islands around it, which includes elevations from that time; and the
1982 Atwater survey of the Delta.  The Atwater survey compiles three different official surveys onto single map sheets,
which are very interesting to compare.
 
NOTE!  Most of the files are very large so may take a minute or more to load...but its worth the wait.  PDFs open in a new window.  JPGs shown below are "thumbnails"-click on each to see large size jpg.

were reclaimed, other than the farming
families themselves holding the original
grant deeds!


Map below shows the lands for irrigation TO BE SOLD or already sold for agriculture and other beneficial uses in the 1870s.  State and Federal agencies have changed their minds 150 years later, and want to take back much of the prime Delta farm lands for "public benefit" purposes.  Next perhaps the state officials will change their minds about the whole Napa Valley, a much smaller region than the Delta, and reclaim the Napa Valley for more "public benefit" purposes-like making wine for all the lobbiest events.  If large scale eminent domain can be accomplished on Delta lands, no landowner with prime agriculture land, recreation land or housing development will be safe from the 21st Century politicians of California.




































1935 Soil Survey-notice "the Delta" of this time period


Above:  1855 map by the state geologist, Mr. Blake...the written
accounts of the survey including portions of the Delta rivers are
quite informative!
