The Oroville Dam in California finds itself in a situation with the only way to avert an over top of the dam is using an untested emergency spill way built in the 1960's as the regular spillway was damaged by a sinkhole and has stopped drainage of the lake. Evacuations are not issued yet, but with more rain on the way this dam will over top into the emergency earth 1960's drain way. Good Luck to all of you. You may need to evacuate. Please prepare in Advance.

Comment: Update: Tallest US dam in California might collapse, immediate evacuation ordered - sheriffThe sheriff in Butte County, California has ordered an immediate evacuation of all people below the damaged Oroville dam, which is feared to be in danger of imminent collapse, Reuters reports.
"Immediate evacuation from the low levels of Oroville and areas downstream is ordered. This is NOT A Drill. This is NOT A Drill. This in NOT A Drill," says the statement posted on the Butte County Sheriff's Facebook page.
The statement refers to the Lake Oroville Dam, located 105 km (65 miles) north of Sacramento.
The dam's spillway was
"predicted to fail within the next hour," the California Department of Water Resources (DWR) said at around 4:30pm PST Sunday (00:30 GMT Monday).
"DO NOT TRAVEL NORTH TOWARD OROVILLE," the Yuba County Office of Emergency Services said on Facebook, urging evacuees to travel safely in all other directions and help the elderly.
Update (06:56 GMT)At least 188,000 residents evacuated as water continues to burst through an eroded spillway - prompting fears of massive floodsOfficials have ordered at least 188,000 residents near the Oroville Dam with no word yet when evacuations will be lifted because of the uncertainty about the condition of the dam's spillway, said Butte County Sheriff Kory Honea.
Releases through the dam's main, heavily damaged spillway increased to 100,000 cubic feet per second from 55,000 cubic feet per second on Sunday to try to drain Lake Oroville before a failure occurs, said the California Department of Water Resources. Water falling over the Oroville Dam's emergency spillway has stopped as Oroville lake levels dropped low enough.
Lake levels fell for the first time since Saturday and will now allow for inspection of the area. The threat of collapse due to erosion has diminished, said officials at a recent press conference.
On Sunday night, state water authorities used helicopters to drop containers of boulders to fill in the 250-foot-long, 170-foot-wide hole in the main spillway to stabilize the problem.
The cost of repairing a gaping hole in the spillway for the tallest dam in the United States could reach $200million.
Another storm is predicted to hit the area in a few days, which means California's Department of Water Resources will have to continuously monitor inflows into Lake Oroville.
