Ryer Island
Our goal in posting the following examples of the miscelleanous WRONG maps showing Ryer Island is to emphasize the extent of use of the incorrect Delta island labeling and use in a variety of settings in the modern day Delta planning forum.  If government agencies like BDCP, DWR, Delta Vistion, NOAA and CalTrans can't figure out where the islands and waterways are, how do they expect to come up with correct reports about the same?

As of May 2011, there are still ongoing problems caused by incorrect use of island names, which negatively affect the residents, businesses and visitors to Ryer Island and many other areas of the Delta as well.  Our research has also shown that CALFED-DRMS in particular was wrong regarding many islands of the Delta.  See comparison report.  See also lots of data at http://DeltaRevision.com    What used to appear as accidental mistakes by various agencies, when compared over time and the totality of the circumstances, it becomes apparent there is an intended pattern to the "mistakes" made regarding Delta island hisotry and conditions...its not just about Ryer Island!  Google, USGS, FEMA, NOAA, URS, CALFED, DWR and Delta Vision are just a few of the agencies or agency contractors who are confused about the Delta.....

Google Maps of Delta Islands 2006, 2007 listing Ryer Island and Tyler Island incorrectly.  At one point during the summer months of 2006, Google listed ONLY the Ryer Island in the Suisun Marsh area, so travelers with large RV's trying to get to the occupied Ryer Island got lost in the Montezuma Hills instead!  More on Google conflicts
