'THIS IS NOT A DRILL': Residents in areas of Oroville, Calif. ordered to evacuate as dam is predicted to failpic.twitter.com/b49uOFvDDt— Breaking911 Nature (@B911Nature) February 13, 2017
Butte County Sheriff Kory Honea said the evacuation orders affect 188,000 people, AP reports.
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).

“Oroville Dam itself is sound and is a separate structure from the auxiliary spillway,” the statement read.
The emergency is the first time in the 48-year-old dam’s history that an uncontrolled spillway is being used, local NBC affiliate KCRA-TV reported.

On Friday, only 7 feet (2 meters) were left until the dam was to reach its full capacity.

“Around 3pm we were advised of a hole that was developing near the lower edge of the alternative slash emergency spillway, which has been used to reduce the level of the lake given that the main spillway was damaged a couple days ago,” Sheriff Kory Honea told a press conference, adding that he was advised of the “imminent danger” that it would collapse.

“We had to make a very critical and difficult decision to initiate evacuation,” he said, adding that he “could not risk the lives of thousands of people.”

“About 10 minutes ago, the DWR told me that the erosion that caused all this concern was not advancing as rapidly as they thought,” the sheriff said.
He announced that helicopters will be engaged in the operation to drop large rocks to “plug the hole.”
Acting Water Resources director Bill Croyle also confirmed to reporters at around 10pm local time that the immediate danger had passed, with water no longer flowing over the eroded spillway.
He cautioned, however, that the situation remained unpredictable.
Officials are set to re-evaluate the evacuation orders at dawn, Reuters reported.
Measuring 770 feet (230 meters) high, the Oroville dam is the tallest dam in the United States. It exceeds the Hoover Dam by more than 40 feet (12 meters).
