| Below you will find maps from
different studies about the Delta. Click or double-click on each map to
see a larger version of each. Some of the wrong maps of the Delta are
in pdf format-click on the link after reading the description of what is
wrong with the map and why its important to the particular study or
report that used the map. For reference purposes, the first map links
below bordered in green are for the most part correct maps of the Delta
EXCEPT for the missing label for Ryer Island in the Suisun Marsh area.
Since this map is very large as a pdf, you can make it as big as you
want in a seperate window to make comparing the Delta maps easier. Note
that all maps were found in public documents and it is assumed they are
not copyright-please let us know if any map should be removed. The
examples below are provided with some comments and references.
Review these before going to the next series of pages showning over 100
wrong or intentionally misleading maps of the Delta, and including some
wrong photos or their captions. Many more wrong maps of the Delta. |

2011 Map from the BDCP EIR/EIS draft.
Isn't it odd how the spokesperson for the BDCP, Karla N., has been to
Snug Harbor, went on a boat ride along Steamboat Slough over to Cache
Slough and back to Snug Harbor, went on several Delta EcoTour trips
right past Snug Harbor on Steamboat Slough, and their current plan
either ignores the existence of Snug Harbor or revises its name and
business to be a sailboat marina. (BDCP written description is
about Hidden Harbor about 4 miles south of Snug Harbor on Steamboat
Slough) This is a quite intentional "mistake" on the BDCP drafters
... any guesses why they would do this? |
 |
If you go to the link provided on the map to the
left, you can see the full size of the map...the map key says the water
is the blue color (logical) but what is illogical is that most of the
Delta's waterways and sloughs do not show in blue...gives the impression
there is not that much water here...perhaps the maps should be relabeled
the DSC vision for the future of the Delta? |
 |
DWR wants to rewrite California navigation
history...read what the publisher of California Magazine from the 1850's
to 1865 has to say about what travel was like on the
Sacramento River, Steamboat
Slough and the San Joaquin River! |
 |
DWR has some misleading maps online in 2011.
Here's a "print screen" with notations added |
 |
"WEAP" is an interesting name for the EBMUD plan
to divert more water from the Sacramento River watershed. Some of
their data seems to eliminate the upper portion of Steamboat Slough
and/or Sutter Slough. Go take a look at their website |
 |
|
| |
|
 |
Waterboard's map of the Delta...Where's the
Sacramento Ship Channel? The other waterways of the Delta? |
 |
Look at the map to the left...I added the ?
where McDonald Island is located, which is an underground gas storage
area in the Delta. Notice how the lines are not listed, even
though they would be classified as "major" natural gas lines? |
 |
This 2011 map is supposed to show major water
projects or conveyance routes....notice the DCC is missing even though
the state does receive water from the DCC? |
 |
Last time we checked, neither Ryer Island or
Grand Island were open waters or lakes |
 |
This one is interesting because it revises
completely the pathway of "old river" Sacramento...is Isleton OK with
this? |
 |
This one is just to obvious! |
 |
Interesting how this natural corridors map eliminates the historical and
natural corridors of the area of the Delta where Steamboat Slough,
Sutter Slough and Miner's Slough used to wander! |
 |
By now you should be able to see what waterways are missing and which
ones have been altered on this map |
 |
|
 |
Notice how the waterways around Staten Island are emphasized in this
map? That is part of the CALFED 2000 Record of Decision which
increases flows into the Mokelumne River by various methods...the DCC,
Freeport backflow pumps, Fulsom south diversion are ways Sacramento
River water can be diverted into the Mokelumne conveyance facility or
"central canal" plan of the CALFED 2000 ROD. |
 |
Interesting direction for the flow of the water on Steamboat Slough and
the Sacramento River...does this indicate a revision to the Sacramento
River by Isleton as the other map indicated? |
 |
So many maps omit the Sacramento Ship Channel that one has to assume it
is being eliminated or used for other purposes. |
 |
So when we read the reports about the plans for pre-flooding of some
Delta Islands, and also read the reports from DRMS Phase 1 about which
islands are not worth "saving" when the report talks about Pierson
District should we assume its really about Ryer Island? When they
write about Sutter Island, is it really about Grand Island? That
plan to enlarge Clifton Court Forebay to include Coney Island...all the
way up north towards Sacramento? Is there a new Clarksburg Tract
now?
By the way, we're not confused about where places are in the Delta but
the "scientists" who drafted some of the reports sure are!!! |
|
|
|
|
|
|
|
|
|
 |
In this 2011 map McCormack Williamson Tract looks like a lake. As
of 12/15/2011 that still is not the case but its quite clear that is the
intent of the BDCP and DSC Delta Plan |
 |
Again, where's the "major" waterways of the Delta? |
 |
DWR paid at least $6 million to URS, a huge corporation that often
contracts with government entities, to do the DRMS Phase 1 Report.
Ryer Island flood history was falsified or inflated by DWR or URS, which
made it appear Ryer Island had flooded 3 times...it has not flooded in
the last 100 years, and in particular, despite what the DRMS report
says, Ryer Island did NOT flood in 1986. There was evidence of
underseepage due to the intentional flooding of Prospect Island adjacent
to Ryer Island...but underseepage does not mean a flooded island unless
the state plans to revise the definition of flood! In any case,
the wrong Data found in the DRMS Phase 1 report has been repeated often
by scientists who are unaware that DWR did make corrections to the DRMS
Phase 1 report over a year after the "final" was published. |
 |
This is an example of using different labeling and colors to convey a
message that is intended to be misleading...see video review |
 |
Looks like the Sacramento Ship Channel is planned to be eliminated and
Solano County lands seem to expand a bit |
 |
A more defined nature corridor map shows the Sacramento River but where
is the Sacramento Ship Channel? Cache Slough? Steamboat
Slough? |
 |
Miner's Slough and Sutter Slough and the Sacramento Ship Channel are
missing in this map |
 |

To the left is a map from levee studies in 2004. Ryer Island is
listed as Grand island which puts into question exactly which physical
location the professor was referring to in study results. |
 |
This map is supposed to be Delta Islands (only)
but it includes places not part of the "legal Delta". It also
makes up names. There is a Delta Island named River Junction down
in San Joaquin area, but there is no record of a "River Island", which
is what this map calls Ryer Island next to Ro Island.
2011videos/wrongmaps/delta_vision_cover_wong_island_name.pdf
Even though advised of the problem well in advance of final publication,
the Delta Vision writers did not get the cover right! |
 |
Ducks Unlimited map from 2006 doesn't name the
Delta Islands, but also does not locate the Sacramento River correctly. |
 |
URS seems to have done many of the maps for DWR.
This 2004 map does not list both Ryers. That is strange, since URS
has been proposing restoration work for the Ryer Island in the Suisun
Bay.
but in the Status & Trends report the confusions of the two Ryers begin
to show |
 |
2011videos/wrongmaps/1997_other_ryer_seismic_study.pdf
This study of the Ryer Island in Suisun Marsh later was quoted as
applying to Ryer Island above Rio Vista
Which brings up the problem of the DRMS Phase 1 "Final" report published
in 2008, corrected in March and December 2009, but it still contains
incorrect data regarding individual island flood history, and inflates
data by including islands outside the Delta to skew the means and
averages. The "correction" to the Ryer Island maps is
misleading....go ahead, take a look:

The map in this study indicated the Delta
already looked this way... |
 |
Delta Vision map confuses several island
locations: Andrus and Tyler are labeled on one island; the real
Andrus where there are many marinas and resorts is not labeled, and the
smaller Ryer is not showing. |
 |
This flood history map is SOOOO wrong in so many
ways, it will have to be added to the list of reports that apparently
used DRMS incorrect data regarding flooding of Delta Islands (the
subject of a different series on the Delta) |
 |
Here's another example of a map of Delta flood
history which was based on the false data from the DRMS Phase 1
report...this is Laird's report for AB 1200 |
 |
Yikes! Lots of agencies are using the
incorrect Delta flood history from DRMS |
 |
Steamboat Slugh missing but the referred-to fish
studies trackt the fish through Steamboat and Sutter Sloughs. |
 |
My guess is a 5th grader who'been taught some
basic math and how to do basic charts could figure out the 3 ways this
map is intentionally misleading the viewer |
 |
DSC seems to be eliminating Miner's Slough,
parts of Sutter Slough, opening up Elkhorn Slough and it makes changes
to 7 mile sough |
 |
This map is from FEMA...they based it on the
false flood data from the DRMS report, apparently. |
 |
Study tracking fish down the Sacramento River
through Steamboat Slough, even though the study says Sacramento River |
 |
DWR map describing the historic Delta as
freshwater, when many other DWR maps in the last few years say it was
brackish... |
 |
Notice how the connection between the Sacramento
River and the Mokelumnke no longer is there? DCC is missing in the
map for some reason. |
 |
The labeling on this map makes it look like
there are two different Deltas |
| Lets take a look at some maps that
list the waterways of the Delta. |
 |
Notes:
Sacramento River historically was also called "Old
River" from the confluence of Cache and Steamboat Sloughs (i.e. Ida's
Island-Vierra's) to the junction with the north end of Steamboat Slough.
"Old River" Sacramento kept that name until about 1920 according to
county maps and records.
Steamboat Slough is considered a tributary of the
Sacramento River, but in the past was called the Sacramento, West
Branch, Middle Fork, and some maps show that Steamboat Slough started at
the confluence with Sutter Slough. However, since about 1870 its
been called Steamboat Slough for its entire length.
San Joaquin River also had many branches. Its
been referred to as "Old River" in more receint times, which tends to
confuse the unaware with past articles written about "Old River"
Sacramento. |

|
 |
Another Artsy map, this one from Boating and
Waterways, but the location of the Sacramento River and Steamboat Slough
are confused. |
 |
Another Ducks Unlimited map still confusing the
location of the Sacramento River-that is Steamboat Slough! |
 |
The PBS review of Gold Rush days seemed to
ignore the fact that Steamboat Slough was the preferred travel route to
Sacramento as it was less travel time and deeper water...until the
hydraulic mining practices started! |
 |
NOAA, who published the nautical charts, now
lists Steamboat Slough as the Sacramento River...when did it get
renamed?! |
 |
Sacramento River Watershed website shows a
different path for the lower Sacramento River but does not include
Steamboat Slough...not sure why. |
 |
The US Census map shows Steamboat Slough as
Seven Mile Slough...which probably throws off the Census for Solano
County since there's lots of families who live on Ryer Island and maybe
one or two along Seven Mile Slough which is in Sacramento County. |
 |
Missing Steamboat Slough, Miners Slough, Sutter
Slough |
 |
There are two islands named "Ryer" in Solano
County. The Delta Vision group was told about various map mistakes
in the draft, and those were corrected EXCEPT that Ryer Island in the
Suisun Marsh area was renamed "River" which might get confused with
River Junction in the South end of the Delta along the San Joaquin
River. It might also explain why some of the soils, seismic and
flood reports regarding Ryer Island are wrong in the DRMS studies. |
 |
Another example of wrong labeling of island
names |
 |
Another example of incorrect data regarding
Delta Islands |
|
|
|
 |
UC Berkeley is a bit confused as to where the
Sacramento River is located, but its not a very accurate map in many
other ways, so lets call this one an "artsy" Delta map. |
