> Sacramento delta levies Hmm... as someone currently living in Woodland - which is right on the other side of the causeway across the immediate spill area for those levies - I'm wondering how safe this winter will be. Woodland is an old town, so it's on slightly higher ground than some of the surrounding areas, but apparently that may not matter.

As a Davis resident, I was curious to get a more detailed map of the flood areas for a hypothetical ARkStorm than the one provided by the Wikipedia article on the topic [1]. To that end, I created an animation, morphing between a google maps screen-cap, and the USGS map of the flood areas [2]. I didn't get the alignment just right, but from the look of it Woodland would appear to be underwater (at least, according to this USGS flood model). That all said, is there really any evidence that a strong El Niño has anything at all to do with an ARkStorm? The Wikiepdia article on The Great Flood of 1862 [3] has this to say: "The weather pattern that caused this flood was not from an El Nino [sic]".

  Wow, that's interesting. It does look like the worst scenerios could (at least in theory) overflow the causway area and hit Davis/Woodland. It's right on the edge, though, so that may only be a concern in the most extreme events. I may have misinterpreted the situation re: ARkStorm, and I agree something closer to a "strong El Niño" seems far more likely. Still, it's interesting to know that flooding in this area is at least plausible.
