If you lived below the Oroville dam and given the current circumstances, and I realize the government has everything under control, and you might lose your job, but would you bug out right now, Sunday, 2/12/17 ?
I would be ready at the drop of a handkerchief to haul a$$. Once the paved portions of spillways in earthfill dams is damaged, undercutting can go really fast. The fact that the emergency spillway is unpaved, it is subject to washout, especially if the rain capture area continues to load the reservoir.
I wouldn't live in that area... But if I did win a house in a poker game, I'd have everything loaded, fueled and carrying a SAME radio 24/7. And I would sell the place ASAP. Heck, take a 50% hit and still be happy to get out!
If I lived below the dam in Yuba City or Marysville... Definitely Any other area below Oroville, it would depend on what elevation my home sat at.. An instantaneous breach of Oroville may cause the upper Sacramento Valley to flood.
This may sound familiar - Teton Dam Just a little over 4 hours from "leak" to complete failure. No way would live downstream from a dam....esp a 'earth fill' dam. On Saturday, June 5, 1976, at 7:30 a.m. Mountain Daylight Time (MDT), a muddy leak appeared, suggesting sediment was in the water, but engineers did not believe there was a problem. By 9:30 a.m. the downstream face of the dam had developed a wet spot which began to discharge water at 20 to 30 cubic feet per second (0.57 to 0.85 m3/s) and the embankment material began to wash out. Crews with bulldozers were sent to plug the leak, but were unsuccessful. Local media appeared at the site, and at 11:15 officials told the county sheriff's office to evacuate downstream residents. Work crews were forced to flee on foot as the widening gap, now larger than a swimming pool, swallowed their equipment. The operators of two bulldozers caught in the eroding embankment were pulled to safety with ropes. At 11:55 a.m. MDT (UTC-17:55), the crest of the dam sagged and collapsed into the reservoir; two minutes later the remainder of the right-bank third of the main dam wall disintegrated. Over 2,000,000 cubic feet per second (57,000 m3/s) of sediment-filled water emptied through the breach into the remaining 6 miles (10 km) of the Teton River canyon, after which the flood spread out and shallowed on the Snake River Plain. By 8:00 p.m. that evening, the reservoir had completely emptied, although over two-thirds of the dam wall remained standing. (Teton Dam - Wikipedia)
Teton Dam was Flawed, as designed, from the getgo..... The Soil Engineering Firm WARNED the FEDs, that it was in the WRONG Spot... but nobody listened.... Just another failure of BureauCarats who thought they knew better than the Engineers....
Good move! I left the East Coast (Delaware) over 40 years ago. Never looked back. The place sucked then. It's worse now.
Unbeknownst to us we bought a trailer in a dry swamp amongst hundreds of others that had been there for a very long time. It rained and the pumps failed and the swamp became a lake over night and most all were lost. Know your environment.
Noteworthy for being the last dam built by the FedGov. All they do now is tear down dams and we get the resulting loss of hydropower....
Look at the damage done to the spillway, notice any thing remarkable?!?!?!? NO RE-BAR or any other reinforcement. No post tension, no anchoring of any kind, A ticking time bomb this was, and now we reap what we sow!
Contractor cutting corners? It has happened in California before with the I-5 project... People went to jail over that one!
The Butte County Sheriff’ Office released the following statement on Facebook: This is an evacuation order. Immediate evacuation from the low levels of Oroville and areas downstream is ordered. A hazardous situation is developing with the Oroville Dam auxiliary spillway. Operation of the auxiliary spillway has lead to severe erosion that could lead to a failure of the structure. Failure of the auxiliary spillway structure will result in an uncontrolled release of flood waters from Lake Oroville. In response to this developing situation, DWR is increasing water releases to 100,000 cubic feet per second. Immediate evacuation from the low levels of Oroville and areas downstream is ordered. This in NOT A Drill. This in NOT A Drill. This in NOT A Drill. Keep an eye out, this could get exciting.....

The emergency spillway is just soil, not reinforced concrete.. Shown is the Main spillway, the emergency spillway is to it's left.
Well, it's going to suck for hydro power customers. And anyone down stream for a while. You couldn't pay me to live below the dam.
Anytime there's a situation like that(some potentially devastating occurrence related to the weather affecting infrastructure) and the .gov response "We've got it under control", that would be time to LEAVE...at least that would be my opinion.
