OROVILLECLIFORNIA, : NOW IS THE TIME TO PUT EVERYTHING IN BOXES
If you live on the flood plain below Oroville dam, I strongly suggest you not procrastinate and begin packing boxes now. Put all your most valuable stuff in boxes NOW. Make sure whatever you box up will fit in whatever you have to get out of there. The dam is not, at present, in imminent danger, however the water level keeps rising and has now gone up 20 feet since they shut the main spillway off. With less than 40 feet left to the top of the emergency spillway, they don't have anywhere near the capacity needed to hold spring runoff, even if the reservoirs upstream were not already full.
How much confidence do you have that the main spillway will survive extensive use? They are going to have to use it. I'd definitely pick through stuff and box the best right now. And don't wait for any evacuation orders, they proved beyond all doubt last time that they will wait way too long. If I lived below that dam, I'd watch the chart, and bug out at 997 feet. Actually, I would not live below the dam this long after the emergency spillway proved it's worth. I'd have already moved.
