They ought to wait until some of these large storms have passed....maybe longer
Jerry Brown owns this one.
In my seriously uninformed opinion, those below the dam are in a very precarious situation but my advice is:
While the gover-stapo will let you, use this opportunity to get back in, pack up your valuables and get them and your loved ones to higher ground. If you absolutely have to go back have several alternate plans to get to high ground in short order and keep careful watch of the inflows so you can be ahead of the rush when the government lackeys finally do get around to issuing the next evacuation order.
Listen for sirens and Pray the main spillway doesn’t unzip back up all the way to the top without any notice.
