Is Google Maps into Delta fortune-telling?

What the heck is this?

I went to Google Maps just now and found this interesting mapping of flooded islands. This is current Google mapping for the Delta region. Is Google getting into the fortune telling business?

I'm off to the boat and won't be near the internet again until Tuesday evening. There could be some fun with this.

Now THAT is scary!!!!! 'Course g00gle is a SF company, so folks there are probably of very liberal bent politically.........
 
Interesting. I'm guessing that they've applied some of the extra data you can find on Google Earth to the web-Google maps feature, which includes altitude, and that they are assuming altitudes below sea level are flooded. But who knows?

After the next big one this will all be underwater anyway, right?
 
Google apparently thinks the Navy still owns and operates Rough and Ready Island according to that map as well.
 
Exactly. Only the satellite version shows the latest, as of when the satellite photo was taken. Lots of misinfo on all mapping sites.

I think BTG has a very plausible explanation: they are assuming altitudes below sea level are flooded.
Way to go BTG!
 
yzer, at least our marinas are still accessible by car. There are some enviro extremists who would like nothing more than to see the delta looking like this.
 
I think some environmentalists would like to see those additional blue areas show up as green on the charts: big tule marshes. The problem is it could take a couple of centuries to get the most deeply subsided islands back to sea level. OTH, there are some water interests who would like to see those subsided areas appear blue on the map: additional surface water storage.

People have different agendas about what they want to do with the Delta but everyone agrees that you can't turn the clock back to what it once was. Unfortunately (IMHO), the agenda that's backed with the most money usually wins.

The Delta Loop is an interesting case. That's Andrus Island south of HWY 12 and between Jackson Slough and the Mokelumne. It's one of the most deeply subsided islands in the Delta and if it gets flooded then Isleton and Brannon Island could flood as well: unless there is enough grade on HWY 12 to stop it. From what I've heard, some plans and zoning for Brannon and Andrus Islands are already cast. North of HWY 12 will be fully developed as Isleton grows. South of HWY 12 will stay agricultural as long as it's sustainable with limited commercial/residential much like it is now. Things could change, of course.
